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.

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??

Really love the Lollipop rom, but since I am on Bluegrass Celluler, when the rom is installed, the data connection doesn't work. No phone or sms or mms is available. Bluegrass uses their own roms and special data connection settings to work with Verizon towers. If any one has overcome this, I would like to know. Have googled to no end and never found an answer to get phone and sms working with custom roms with Bluegrass Cellular as the carrier. Thanks guys......
bluehrass
I feel your pain ......I too am with bluegrass and I tried several Roms on my moto x 2014. I had no service or internet either. I went back with my backup the first few times no problem then I had trouble with recovery, getting phone to see the files etc....anyway after a few days I finally got back to my original but now my cell signal is weak and data is horrible...no 4g ever and seldom even 3g....maybe I picked up the wrong baseband or modem along the way??? If anyone has any advice or a bluegrass baseband I could try it would be much appreciated ....thanks in advance.....
I have an S4 mini and it updated using Samsung Kies. After that no data connection. Bluegrass re-flashed it for me. It seems this is something they do on a regular basis. You might try that.

You Can Correct The Issue With Advanced Signal Status from the app store.
Possibly try..

CM12.1 D2VZW from download.cyanogenmod.org worked for me on PagePlus. I don't recall if BlueGrass is a provider or reseller, hear ccommercial often. At worst you will have to edit APN and or ##DATA setting. I would recommend downloading Partition Backup from Play Store by wanam. At minimum open menu and choose Backup first blocks. That makes a unbrick image for real emergencies. I would also backup your efs, modem, modemst1 and modemst2. The first time I installed CM12.1 I lost my network/serials and sound. I had the best luck with 5-17-2015 nightly, which kept my sound. Worst case you can do like others suggested and take it in store for restore. Maybe with some talking you can obtain the actual restore file.
Note : Check the ##MSL settings on bg rom and note the settings for adding into the custom rom of your choosing. Code is typically 000000,but maybe different. This is a subset of service program only available on TouchWiz/Stock roms
Hey, got the phone and sms working using Advanced Signal Status from Google Play. Thanks for your reply. The major issue I am having now is no sound at all and no mic with any Serrano Lexx Lollipop rim. I have an S4 Mini SCH-I435L.
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

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.
According to the specification sheet, my Le Max 2 (Model X820) has all the bands required for Verizon. I am always interested in finding out whether it can be used on Verizon network, and if so, how. I have done quite a bit of experiments and would like to share my findings.
First thing first, and I am sure most of us know it - you cannot activate a Verizon SIM using this phone. It must be an activated Verizon SIM that you pop into this phone.
I am using an Xfinity Mobile SIM, which uses Verizon. It is not a Verizon prepaid or post-paid SIM. I do not think it makes any difference in my experiment though.
I can get one of the two working conditions: (1) 3G voice + 3G data, or (2) 4G data but no voice. In case (1), the phone is connected to Verizon’s EvDo network. Voice works fine. Data also works, but it is only 3G. In a phone call, data is disconnected, which is what an EvDo network does. In case (2), LTE data works, but Voice is out of service. I did try VoLTE but to no luck (The same SIM works fine with VoLTE in a Nexus 6P).
To me, only case (1) is a workable solution. When one would like to think in case (2), we can supplement Verizon’s LTE data with voice from another SIM. It does not work. When LTE data is set to use Verizon, the other SIM does not work at all. Some people may be fine with Hangouts or a VoIP solution though.
For a dual-SIM set up, it goes like this: SIM 1 – Verizon, for voice/SMS, SIM 2 – ATT or T-Mobile, for data. The drawback is that when you are in a call, data is disconnected.
But even for such a set up to work, there is some work to be done. Based on my limited knowledge of how Verizon’s CDMA network works, it seems that for voice to work, some provisioning must be done (information such as MDN, PRL, etc.). I find that this provisioning is only doable in a Chinese stock ROM. Once that is done, use TWRP to make a copy of the EFS partition. That is my savior. With such a “provisioned” EFS, it is possible to use Verizon in custom ROMs such as RR or lineage. If this EFS partition is overwritten, then the phone will not work with Verizon in case (1).
I know in the past, people have used software such as CDMA workshop, or Qualcomm’s programming software to set parameters for CDMA network. I do not know if it will work for this phone or not. But that is clearly beyond my skill level.
How do you get 3g voice and 3g data work?
Heyyo, tbh I made a build of LineageOS 15.1 with some kanged verizon files from Sagit (Xiaomi Mi6) but of course I can't test it as I am in Canada... if you're willing to try it out and report your testing it would be appreciated.
LineageOS 15.1 test build with Verizon files:

This is the change:
https://github.com/TheMuppets/proprietary_vendor_leeco/pull/25
I cannot test it since I am not on lineage. Op mentioned he can get 3g voice and 3g data. I would wonder how to get those since I only get 4g data.

Sorry for a late response.
For 3G voice and data to work, I chose to force 3G in settings. I used the RR ROM. Settings --> More --> Cellular networks --> Preferred network type: Choose 3G instead of LTE.
You can also use the dialer, enter *#*#4626#*#*, then Phone information. You can choose network mode there too.
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
*#*#4636#*#*
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.
