Hi All,
I know its a topic which has been addressed differently in different threads. I am a user from India and have a GSM SIM. I have got a Verizon S4 phone. I tried using it with Vodafone SIM and get a problem in using it. Surprisingly a NOTE 2 from Verizon works just fine. I am able to use it for data with 3G but not able to use it for voice. Following steps have been tried already.
- Default Options of using Global Mode and GSM/UMTS ** Doesnt search the network at all.
- Hidden Menu Changes using # codes. ** Shows network but emergency mode only.
- Phone Info app to change the mode. ** Shows network but emergency mode only.
- RF Band change using the hidden menu. ** Shows network but emergency mode only.
It does say that it has GSM radio but cant be used for some software reason I suppose. I checked with Verizon Rep and was told that it cannot be used in India with a GSM SIM and would need the Verizon SIM only to connect with International Roaming.
Can I install a I-9505 ROM on this and then would it pick up the GSM signal for voice and data. Please help.
I don't think your Verizon rep is correct. I bought a Verizon S4 just before going to Europe for 1 month. I used first a gsm SIM card from Germany, and then a gsm card from France. I had to add APN's to get data (I used "offline sim APN database" from the market to help get the necessary APN info), but had no trouble with voice or data for my entire trip. The gps and navigation services on the phone were extremely valuable on a couple of occasions, as was the wifi hotspot. In France, you can purchase 2 GB of data service for 20 Euros. I checked with Verizon global services ( 908-559-4899 outside the US or 800-711-8300 from inside ) before I left, and the Verizon S4 was sim unlocked out of the box. They did not make a big deal of my plan to use other SIM cards either.

Installed WamanLite I9505 ROM
Hello All,
I found that Wanam Lite I-9505 ROM can be installed on Verizon S4. I installed it and patched it with Loki-Doki patch to boot up as I got the Verizon Software error. Yet my phone doesnt pick up the GSM signal for voice and SMS. It picks up the signal and I am able to browse internet on it but no calls or SMS. Please help...!!
Is there any way that I can install or flash a regular GSM radio over the phone ? Or tweak it in someway to use the GSM signal as primary for voice and sms.

I have also Verizon's S4 (i545) and use it in GSM network with only one small problem - it will not send SMS with in-ROM SMS apk to international-formatted numbers (+380-XX-XXX and so on), but send without problem to local-formatted numbers (XX-XXX...) All the rest is working good.
Could you tell me please - how did you get to install i9505's ROM on your device? I have also Verizon's error after installation, and don't know how to run it...
Hi I too have the vzw s4 in india.. and niether voice nor sms is functioning on it.
By rooting it and installing apn manager I was somehow able to get the data 3g working for vodafone ind.
I too am struggling to find a solution to this.
Ive haventvyet flashed it. I came across a guy who said he will be able to get it working but somehow I havent yet been abke to follow up with him.
Guess we both are on the same boat.
Lets keep in touch and update if any of us finds a solution to this.

You all can try to flash my port of ARHD 2.0 ROM, that can be found it this thread:
http://forum.xda-developers.com/showthread.php?t=2346365
It is fully GSM and as international as regular GSM-version of S4. CDMA can be turned on only on hidden test application. Everything else is working and was tested in different networks.
I too created a post seeking help in this regard but didn came across anything concrete yet.
Everyone out here believes it to be a world phone and some have even been using the gsm network in europe but its not working in india.
Ive failed to understand that how come its detecting signals with functioning data is not working on either voice or sms.
Tmobile and atnt gs4 guess have this service menu from where they can be network unlocked explicitly..but unfortunately I havent yet come any such thing for vzw gs4.

I tried installing the ARHD 2.0 ROM but still the same issue persists. The phone picks up the signal for data but when tried selecting network manually or automatic using the GSM / UMTS option, it says disable data to search networks, when data is disabled, the phone shows available networks says phone registered to network but the status still says Emergency Calls Only. Also if tried dialing a phone it says no network available. There has to be something in the modem settings which can be tweaked through the service menu which will change the use of GSM for voice and data and not use CDMA.

Did you do a full wipe when flashing ROM? It is mandatory. You will lose all your data though. If there will be no changes after full wipe - then try to install this card into another phone and ckeck if voice calling is working.

I did a full wipe. I have 2 Galaxy S4's and also an Optimus G. The card that I am using is my regular SIM card so its not an issue with the card for sure. The ROM was installed on both the phones and neither of them picked up the signal for voice and SMS.

Ok. To go and chose type of radio-band you may install Battery Monitor Widget from Google Play (well, the main purpose of this app is different, but it is what comes first in my mind). Put it's widget on the desktop, open it and go for bottom right button, named Test. There you can first menu (Device Info) and there you will be able to change all variations of the radio bands and their combinations, available for i545. If non of the combinations will help - mosty probably your operator works on unsupported for this phone cellular format.

I have the Phone Info app which allows band select. Tried on all possible modes. Same issue persists. Strangely the Note 2 purchased from Verizon works flawlessly without any mods or changes. I am thinking of giving to some professional phone guy who may have code level flashing or modding tools to try and fiddle around with settings of the modem or the radio to pick up the signal here.

Hey phrozenwire, I am able to use both voice n sms now in my VZW GS4.
And I literally did nothing to make the voice n sms functional. I too had troubles for like 2 weeks and it didn work for me then.
I rooted the phone to add apn settings and the data got activated. But today morning when I woke up ... surprise surprise .. it began to work.. rcvd sms and calls and I was so happy. . Last I remember I switched on the power save mode and my cell fell down twice and guess it did the trick for me.
Thanks all for your help and comments.

Hello Folks,
I was planning to by VZW S4 to use in India & by looking at all your comments it makes me not to buy. Any further updates after so much of discussion on this phone to make it work in India's cellular service. I see the last post was on July 2013 & now any further lucks/success in making this phone work over there in India??

1. Insert Straight Talk ATT sim
2. Set mobile networks to GSM/UMTS
3. Go to system updates and select update PRL
4. After its updated go back to mobile networks and switch it from global back to GSM/UMTS (it will auto switch when you update prl)
5. Go to roaming in settings and scroll to the bottom and set APN
6. Download Signal Check or Signal Check Pro from the play store to show data signal in the status bar
7. The no sim icon will still be in the status bar but you can remove ot with tweakboxand set carrier text
YOU WILL HAVE TO REPEAT THIS EVERYTIME YOU REBOOT YOUR PHONE SO ITS TEMPORARY UNTIL WE GET FULL UNLOCK
PLEASE SHARE AND GIVE THANKS
(I have only tested this with an ATT ST SIM)
I installed cloudy and used network app from the play store and picked cmda/gsm/lte everything works. I didn't even have to set the apn or mess with the dialer it is all good ?
I registered my phone with Straight Talk a couple days ago and I've been trying to get it to work. I've looked everywhere and Straight Talk has lived up to their reputation of having terrible customer service. Anyway, they've confirmed that my phone is activated, but I can't make a call or anything. I'm thinking it has to do with my settings.
Just to cover all the bases, I tried to activate on the CDMA network via the network access code, but I couldn't register my phone due to no coverage in my area (which I know is not true). So I registered on GSM with the ATT SIM card. My Sprint service no longer works, although I'm showing signal bars in the status bar. Whenever I try to make a call it says "Unable to validate your account. Please contact customer services."
I tried the steps listed in the first post but whenever I switch to GSM/UMTS and try to update the PRL it says "Authentication error. Please try again later."
It's also worth mentioning that my phone is rooted and I have frozen a lot of apps, most of which are listed here:
http://forum.xda-developers.com/sprint-lg-g3/general/sprint-g3-bloatware-list-t2873199
If anybody out there can help I'd greatly appreciate it. I'm not sure where else to turn.
You can try my guide it may allow you to fully unlock your settings so you can do what he is saying above.
Here is the thread link: http://forum.xda-developers.com/sprint-lg-g3/general/how-to-gsm-unlock-t2961099
Ok, after much research and many reboots, I've finally got it working. I tried several different methods but the one that finally worked for me was installing the CloudyG3 rom. I'm no expert by any means but my guess is because you have to completely overwrite any evidence of Sprint that is preventing the other carrier's SIM card from working (for me this was ATT through Straight Talk). I had to set my Network mode to GSM/WCDMA/LTE auto. My data is not quite as fast as I had hoped at 21.06 down 3.72 up but at this point it's better than nothing.
A couple problems I've noticed so far is after cloudy finished installing and my Lookout was running it's first test it flagged QuickApps and LGBackup as malicious apps. I didn't uninstall them yet because they seem harmless but I did freeze them with Rom Toolbox just in case. Can anybody confirm that they're safe or that uninstalling them won't cause any bugs? Also my messaging app no longer works which is a little disappointing as I really enjoyed it for a stock messaging app. Anybody know why this is?

Hey everyone. I just bought an unlocked, unused (new) galaxy s4 I545 (Verizon) and it wont send out text msgs with my T-mobile sim card. I do receive (inbound) text; but no outbound text msgs. Calls and web surfing work fine.
I'm aware that this is very common problem when trying to go from Verizon to Tmobile with galaxy S4 phones, but i have not been able to find a straightforward solution to this exact issue. Has anyone been able to solve this? I did find this one thread that addressed this problem, but it's quite confusing --> http://forum.xda-developers.com/galaxy-s4-verizon/help/noob-s-stuck-oc1-lollipop-t3116732
thanks in advanced.

I have the same issue. Tried every thing that was suggested by T-Mobile and they say that the phone is broken. However, when I put a Verizon SIM card in it, it works fine.

I tried changing all the APN settings. These are the same ones T-mobile had me switch. There is another post where the user discovered his SMS/MMS works when on 3g, but not 4g. The workaround was to Root and then change a setting to use only 3G. My problem is that I cannot get Kingroot or any other app to root my phone. They all fail.

What build are you running?
F1
I was able to root my I545 yesterday after months in limbo........ I used Kingroot (not Kingoroot). I tried it 7 times from the phone, and it failed.... then as recommended by many users, I scrolled to the bottom of the kingroot page on phone (after root failed). It said I should use the desktop to root it. Soooooo I set Google translate to "English" and loaded KR (Kingroot) on my desktop.... It WOULD NOT open Kingroot. So (on my desktop) I opened KR WITHOUT english translation. and it was running (on my desktop). Once it was opened, everything was in Chinese (of course). BUT.... it has screenshots that walk you through it (although in Chinese). I attempted to root the phone (by using screenshots only, since I do not know Chinese), and it rooted it first time My advice, use Kingroot as described using your DESKTOP computer and cable. That should do it
NOW my problem, is I have to flash my VZW S4 (OC1 lollipop), to a t-mobile rom...... so I can have wifi calling with my dedicated number Of topic:..... if anyone can do some Q&A with me on that topic I would be appreciate it GREATLY.
Hope that helps ya
---------- Post added at 08:30 AM ---------- Previous post was at 08:09 AM ----------
BTW.... I have the same issue with my text messages (no outbound sms) when I am on 4G. There is a write up on the forums on how to possibly remedy that, but I get hit with.... "MD5 has to many hashes" and I cant go any further... Im still trying to figure out what the hell MD5 is.
ATTENTION to MODS, and OP's:
I am seeing more and more people (like me) whom are coming to XDA because they have a Verizon S4 (whether its kit kat, or Lollipop), and they are using a T mobile sim. I have made an assimilation though.... These people that are coming to XDA have little, to NO root, rom, kernel, experience what so ever (just like me as well). IWe are looking for a fix (I myself want to flash my phone to a T-mobile rom, activate wifi calling, and be able to send/recieve sms continually). Is there anything that anyone could write to address JUST 2 things......... (1 how to get a Verizon S4 with kit kat, and with lollipop to have a t-mobile rom, 2) If somone elects to leave the phone a Verizon phone, a step by step (tailored for noobs like me and many many others) process for fixing the sms issues from having a T-mobile sim... The write up for the second request thats out there is okay, BUT the common problem is a "MD5" issue when you try to download hiddenmenu.apk. Without being able to download the "hiddenmenu" to our phone, we can't even get to step 2 of the "fixing sms issues"...
Please OP's, and mods........ remember in this tense world we live in, remember one thing......... "NOOB LIVES MATTER!"...... C'mon noobs, say it with me! :good:
I don't think the ROM matters. As long as it's a Verizon variant of the phone you won't be able to flash T-Mobile ROM's. This issue is most likely an APN setting issue. Did you ever try flashing the stock OC1 build for the VZW GS4?
I have the OTA lollipop update.... it came in two parts. The apn settings are set per tmobile . I can send sms however only when it switches to 3g. The problem is, on lollipop, you cant toggle between 4g and 3g like kit kat would allow. So its hit and miss (much more miss than hit...lol). From the sounds of it, the radio mhz are different between vzw and tmobile regarding 4g. The other dilemma i have is that i live in the mountains of oregon so i am 3 miles outside the network.... therefore i need wifi calling. I have a google voice number, but i need my assigned phone number for work purposes.
If what you say is true regarding a rom specific for vzw, i guess i need a vzw based custom rom, that will allow me wifi calling, and also fix my sms 4g issue...
---------- Post added at 05:52 PM ---------- Previous post was at 05:13 PM ----------
Speaking of the 3g and 4g thing...... since i have rooted my phone (via kingroot), and installed supersu, am i able to turn off 4g? And if so, how do i do that?
No, you need a T-Mobile ROM that has wifi calling enabled. But like I said this is probably more an APN setting issue than any.
Here
This ^^^ is a link to the manual if you think you can find something useful in there. I've used like 20 apps that all claim they can Toggle LTE data but I've yet to find one the doesn't just bring me right back to the settings of the phone. I've heard rumors about an app that's $1 on the play store that can do it for the GS4 but I can't confirm that. It seems as though you need some special settings provided by the service provider in the ROM that allows for such changes. I might recommend looking into whether you can flash a T-Mobile ROM to the VZW variant.
http://images10.newegg.com/UploadFi...052213_F4_Rev_FINAL_Rev1_Web1403840347272.pdf
Thanks for the link for the manual. I just checked the APN settings, and they are where they need to be. There are only two different settings/entries that i have found for mmsc, and both leave me with this problem. I have researched, and can find a fix for it if i had jelly bean, or kit kat..... but i have lollipop
I am searching to see if this vzw phone will take a tmobile rom (or a variant). If it will, than i might be in business. Does anybody know if i can roll this back to kit kat, or jellybean since i am now rooted?
Unfortunately once the GS4 is on the 5.0 build the phone's bootloader does not support downgrading-I've tried. I, like you, have a the lollipop build (OC1) on my S4 and I really wish I had not taking that update. Lost story short it was an accident I shan't repeat.
finally got it working
I also ran into a wall after taking my wife s4 i545 from Verizon to T mobile. I finally got everything working. the phone is on OF1 so there's a lot of things you need to do they are all here but scattered and very hard to find. you need to root with wondershare mobilego. then you have to odin flash an OC1 kernel then change the settings to the T mobile settings then get this app called Advance signal status and change the defaul text message number from the verizon to the t mobile number and the mobile networks there too(you want GSM auto). after all that you'll be on 3g or H+ for your data but its not too bad and everything else works great including text. total time about 1 hour but just putting things together is where your time goes. hope it helps
Note if your T-Mobile SIM used to be in an iPhone
I was having crazy trouble getting my SMS and MMS working with a stock Verizon Samsung S4 (SICH-545) ROM. I believe most of the problems I had were due to the fact that I was previously using an iPhone4 as my T-Mobile device. After searching through the internet and finding the proper settings for T-Mobile APN, I was able to quickly get phone calls and 4G data working. However, there were some things that took a while to get working. Initially, I could receive SMS, but not send SMS, nor send/receive MMS. It's now working and here's what needed to be done:
Remove the phone from iMessage (allowed sending of SMS)
Remove the phone from iCloud (allowed sending/receipt of MMS)
Lastly, to ensure you get Voicemail access, change the Voicemail number in your Settings. To get directly to VoiceMail with T-Mobile, dial '123'. There's a different number for accessing from a different phone, but this works directly from your T-Mo phone.
I did not get a chance to read all of the responses on this thread, however, I can probably help resolve if the answer is not already embedded in this thread.
I have successfully rooted a Verizon SCH-I545 with stock Verizon ROM and got SMS/MMS to work. Unfortunately, I have only been successful through locking out LTE. If you want more detail please IM me. Otherwise, here is a quick overview:
1. Root SCH-I545 (There are a handful of methods but Wondershare MobileGO seems to do it for me.)
2. Update APN’s to T-Mobile (fast.tmobile.com)
3. Download Advanced Signal Status. Change Data Signal to lock GSM/CDMA (PRL)
4. Reboot and Enjoy
Worked on several handsets I have flashed.
NOTE: A simpler method would be to flash ALBE95_S6 using Flash Fire then there is no need to deal with locking your data signal through Advanced Signal Status, just use the default Network Settings within the ROM.
Hope this helps.
That doesn't work for me. I can't access Additional Info, AND even when I could, DATA would disconnect... so I'd have calls and texts.. but no data.

I did the same, flashfire albe s6, rooted, busybox, apn change, advanced settings gsm/umts, lost wifi too, but....
I was able to fix it. There is a wifi fix in one of the earlier posts: http://forum.xda-developers.com/galaxy-s4-verizon/general/gogolies-wifi-fixes-t3099951 forgot which one I used. but it all works now (on tmobile that is)
Oh, in case you went and downloaded the latest ota from verizon (f*** you very much), like I did, lol, there's a wifi fix for the OC1 bootloader too, for us flashfire people: https://www.androidfilehost.com/?fid=23991606952597069
here's the directions, nice and slow
root the phone, I used kingroot, then converted to supersu, then install busybox
then install safestrap, if you can (your bootloader is older than and not including OC1) or (if you went OC1 or newer), then install flashfire, like I did. Only thing is, if you muff something up and only have flashfire and not "real" recovery, other than the stock one, it gets kinda stick fixing it, (you have to odin in the verizon stock full image of OC1 and start over, I think, I forgot).
then I installed albes s6 rom, I think its in the unified or maybe att s4 section. its easy to find. Its prerooted, so I just updated busybox and then re-installed flashfire. when you install albes make sure you do a full wipe and flash the oc1 bootloader after the albe rom, in flashfire, that's the only way it'll boot.
ok, so you got albes, now you need to change the apn. I use idoneapp gt 3.8. The guy doesnt give it away for free anymore, and I don't blame him, I was just lucky enough to grab 3.5 (which you need to install 3.8) and 3.8 before he decided to charge for it. Its for the sprint s4, but it allows you to do alot of stuff, even on the verizon variety (lol). You can change the apn, allow wifi tethering, get into the advanced menu to change the radios (gsm, cdma, wcdma, lte, etc) (or you can dial *#*#4636#*#* - sometimes doesnt work though. There are other apps on the playstore to change the apn too, so change it after you do all that other stuff. make sure you have the mmsc and everything else correct for tmobile. I have mine set on lte, gsm, cdma, which seems to work for everything, voice, data, mms. Anyway, good luck and have fun! If it doesn't work, oh well, I bought mine for $13. I also have 3 other s4s, a sprint l720t, the cricket one, and the 970 us cellular. I cant get the cricket or the us cellular to take the tmobile sim, even though I flashed the radios to gsm and the roms to tmobile (pain in the a**), but I think those, although they do have the radios, don't have something else hardware wise to allow gsm, since they are both exclusively cdma. I found the sprint one, paid $10 for the cricket, and $22 for the us cellular (it was brand new though). I get lucky on ebay, people think their phones don't work and they do. I've take all of them apart many times, and most times they just need the usb,mic ribbon cable, which I can get on ebay for $1.89 (there's 2 versions though). Late
I love this phone....there, I said it. But it's driving me crazy.
I bought it from a Chinese retailer, who shipped it with X821 firmware, but the box states that it's an X820. I doubt there is any difference in the hardware.
I would have left everything as it was, but I can't seem to make phone calls (don't have a data plan yet...yeah, I know....) with anything other than 2G, and that is about to go extinct. When I set it to WCDMA, it shows a UMTS connection, with no carrier designation, but the tower is the same one I connect to with 2G. The phone does sometimes show an AT&T 3G connection in the status bar, but I can't make calls, even though I have full signal. When I place the same SIM in my old HTC Inspire, the same monitoring app shows "UMTS - AT&T HSDPA+" and works just fine.
I'm at my wits end. I have rooted, installed TeamSpain recovery, replaced the firmware with the X829 and even tinkered with the frequency configurations through DFS Studio (which did a lot of complaining, and I'm still not sure if the changes stuck 100%). I also played with APN settings and tried the SIM in different slots, both alone, and with another SIM. And after all of that, still no progress in getting this phone to use a 3G or 4G connection to make calls. If I don't set it to "GSM only", no phone calls in or out. I'm essentially right under a tower, so signal shouldn't be an issue.
If anyone is using the same provider in the US, and is not having these kinds of issues, I'd really appreciate hearing what firmware you are using, and/or what you did to get things working.
I am using it on x820 with official stock 0.17s firmware, and did a dirty flash to cuoco92's 17s firmware. Everything works including HD voice calls, and full LTE.

I tried this, as well as the Remix ROM. In fact, I think I've tried just about everything, without success. At one point, I had one of the apps indicating a 4G connection, but the phone diagnostics showed GSM (2G). Even the apps aren't all sure what to make of what's going on with the connections reported by this phone.
Currently on the cuoco92 v35 ROM. When WCDMA is enabled, I see simply a good UMTS connection , sans carrier name, in the "Network Cell Info Lite" app, and no ability to make calls. I also often (but not always) see the "AT&T 3G" sign. 4G or LTE never shows at all, even though the diagnostics show that the phone is communicating with an LTE transmitter, when preferred network is set to "unknown". It won't even let me set things like "LTE only".
Any chance you could set your phone to WCDMA and see what the "Network Cell Info Lite" app shows you? Anyone else with this phone on AT&T?
BTW, I am now using a data plan, which I thought might make a difference. It doesn't. EDGE data only for me . New SIM card is on the way, but my hopes aren't high.
Is it possible for a Chinese seller to have borked the phone so thoroughly with their x821 ROM (it's an x820 marked phone), that it keeps any subsequent radios from flashing properly? I don't know how/why it would work for some and not others.
Starting to really dislike this "phone"......it's more of tablet at this point.
Thanks.
I think APN is not set for AT&T
try this:
"Main steps
To use data services on our network with a non-AT&T device, you may need to program the data settings. The sections below provide the correct settings and steps for programming based on your device type and operating system.
.
Access the Settings menu.
Locate and select Wireless & Networks or More Networks.
Select Mobile Networks.
Select Access Point Names.
Locate and select the option to add a new APN. This is usually accessed by a + symbol on the screen or by tapping the menu button.
Program each field using the settings below.
Save the changes to return to the APNs menu and select the new APN.
Name ATT Phone
APN phone
Proxy Not set
Port Not set
Username Not set
Password Not set
Server Not set
MMSC
MMS proxy
MMS port
MCC 310
MNC 410
Authentication Type None
APN type default
APN protocol IPv4
Bearer Unspecified

Thanks, but I wish it were so simple. I have tried this, and other APN settings. None work to get this phone to be usable on anything other than 2G.
I just received and activated the replacement SIM. Still no improvement. While typing this, I have Network Cell Info Lite app running, and with the Set Preferred Network Type showing "Unknown" in the phone's diagnostic screen, It will switch randomly between "EDGE AT&T" (which works fine) and "UMTS -" (which is useless). Both have strong signals. For a split second before it switched to "UMTS-", the app showed "GPRS AT&T", but only for a split second before it kicks over to "UMTS-".
I wish someone using this "phone" on AT&T in the US, would run this app to compare notes. It may be that that the phone works fine on a full implementation of LTE (i.e. in locations where AT&T have already deprecated 2G) but not in other areas. Still, that doesn't seem to explain why this phone seems unable to register on the same 3G network, used easily by my other phone, with the very same APN settings and SIM.
You would have to call att and check if they turned our phone on to use lte. If your phone is not "registered" as an LTE capable phone it wouldn't be able to pick it up. This phone has all the bands needed for AT&T because I am using it now. All LTE work straight out the box, and i'm on the latest 19s cn rom

I'm a bit confused. Is this what you did to achieve proper function of this device? I.e. calling AT&T and getting them to do this for you? My conversation with their tech person didn't seem to bear fruit in this regard.
Also, which slot do you have the SIM card in? I've used the stock 17s and now on cuoco92 v35 ROM. There definitely seems to be a difference in how the network settings behave, based on the location of the SIM. At one point, after selecting BAND 6 (when it would let me), the phone showed a constant "AT&T 3G" connection, but it was useless. No calls and no data.
Good day all,
I'm encountering an issue: a fairly new phone of mine (Umidigi F1) loses its ability to get data from Verizon Wireless when I install Treble Generic System Images (AOSP-based, typically derived from phhusson's et al work). For clarification, despite being from a small Chinese company, the phone normally fully supports VZW (4G LTE data, calls, and text). While on those GSIs, I get a signal and am able to call people with it, but there is no data from the connection.
The APN settings appear to match the ones that work normally (stock F1 and a Pixel 2), so despite not being able to edit or add a new one, I am led to believe this isn't the culprit. Next, I looked at build.prop; the model, device, and brand info changed from the default states and I believe that VZW may be strict enough not to allow the altered info on their network. Attempting to modify build.prop causes a boot loop, though.
Anybody have any thoughts on what I can do? One of the comments at the top of the build.prop file indicates that it is autogenerated by buildinfo.sh. Should I attempt to modify that instead? Or maybe something else?

many MTK soc devices on pis gsi have this issue with sim based data connection. Some even have issue with sms / text.
I did at one point have data working on one of my mtk phones, only when switched connection typs to 3G. But that was not acceptable because way too slow speeds. A solution may come. but i do not know when.
umidigi-f1-tag
I just got a umidigi f1 and am trying to get it working on Verizon. I have talk ant text(sms and mms) working through sim1. However, like you I can't get data to work.
The odd thing is that I can't seem edit the apn settings. That section is missing from my mobile networks section. I am on a stock rom, not rooted.
The sim I was using is a page plus sim. It gets service though Verizon via Tracphone.
I think my issue is that my apn is not set correctly.
Success!
Go to the phone dialer and dial

Go to phone information and change your preferred network type to lte only
The default is lte/umts which probably just good for GSM phones
You should see a lte connect. Hit the ping test to verify if you can ping Google.com
Edited to say, the phone is kind of flaky with regards to the APN setting so ymmv. It was working for me for a while then stopped...
Edited 2: Okay I figured it out. To reveal the Apn menu on Verizon, change the preferred network to LTE only as above, then unselect 4g in the Mobile Network section for the Verizon Sim. Restart the phone. Next time you go to the Verizon section, there should be an Apn setting item. Create the proper Apn for Verizon because the default probably does not work. For me, I needed tracfone.vzwentp.
Here's the phone info screen
Here's the mobile network section for the Verizon Sim. Nonintuituve but had to disable 4g toggle but doesn't have any effect on speed. After a reboot, Apn section shows up
Hellom did you get it to work on Verizon? If so what are the full steps?
Make sure your Verizon sim card is in slot 1. Sadly, it seems like Verizon works best in that slot so not able to use a micro SD card.
On 2 other phones running on Red Pocket Verizon, everything just worked. No need to do anything extra.
Also disable wifi calling.
On my other phone running on tracfone/page plus, I had to do the extra steps in the previous posts above.
