I have a LG V30 H932 [Certified Refurbished] that is locked to T-Mobile. Since I've purchased to the phone I've had these issues:
Apps time out on cellular data, can't find a connection.
Using the web browser on cellular data redirects me to a T-Mobile landing page saying the device isn't supported (Picture attached).
Interestingly I still can use VoLTE, there is a 4G activity indicator (both up and down), and I receive the T-Mobile error page. So I at least know the 4G connection is good and technically works.
When I've called into T-Mobile support, I get answers ranging from 5G isn't set up yet in my area, to verifying APN settings, to the connection to the cell tower just needs to be reset. Needless to say, none of there "solutions" have resolved the issue.
Have any of you experienced this before, and what did you do to resolve it? My opinion is that this is simply a provisioning issue on T-Mobiled side and I'm not using the right keywords with customer support to get them to address the issue correctly.

i would recommend to contact t mobile support about this since the issue is on their side and the phone is from them...

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.

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.
I have tried this new feature coming with the stock Oreo ROM and received a message from my mobile carrier initially, welcoming me to WiFi calling. All network settings seemed to be working fine, I was also browsing internet with no problems, all apps were connecting and responding as expected. However the first time I tried dialing one of my contacts I've got a message "Server error. Try again later." on the dialing screen itself. It looked like the call couldn't be connected. This happened to all outgoing calls, I suppose to all incoming also although I couldn't confirm that.
I tried many things like restarting the phone, turning data on and off, going into flight mode and disabling it, in the end I reset all network settings disabling LTE advanced services before doing that and enabling them again after the reset, but I still get that error. If I disable LTE advanced, all calls get connected with no problems.
Does anyone know if this is something with a list of supported devices explicitly enabled by the mobile carrier in their network? I am considering calling my carrier for more information but the fact itself I have got a welcome message means the device has been detected as part of the advanced services network. Perhaps there are some network settings I need to enter? Anyone ever used Axon 7's WiFi calling/advanced LTE features on any network?
Does that maybe include VoLTE which the carrier may not support?
https://www.4g.co.uk/what-is-volte/
Well according to the link provided and what I know, LTE is supported by my operator, but I wonder if it needs to be specifically tailored to a phone model by them and/or the 8.0 update by itself is not providing such functionality or it is limited by default. And I think it may be the first since ZTE products are never on the list of supported phones by any operator. But I couldn't claim it for sure as otherwise ZTE would not have included it at all with the 8.0 ROM and there are so many basic or very old models like LG K8 or Microsoft Lumia 550 that are supported.
Has anyone tried using "LTE advanced" on their 8.0 yet?

LTE Advanced = Volte
If your carrier does not support Volte, keep this option off.
WiFi Calling is something separate and not related.
If your carrier does not support WiFi calling, keep this option off.
You should still get LTE service with both of these options off. I personal find WiFi calling to work poorly, so I leave it off even though my carrier supports it. (TMobile US)
Also, there is a Q and A section for these types of posts. Don't post questions in the Guides and News section please.
Thanks for the input. Both of these options are reported to be supported by my carrier on their website. Also I always had LTE before 8.0 so simply wanted to try the new "HD voice and advanced communication service" as described in the latest firmware.
About posting this thread in the news & discussion section, this only relates to Oreo which was only recently released to the public so it is a completely new feature for the Axon. Most of the other threads are too general and since there will still be many people with 6.1 and 7.0/7.1, I would have hardly got any response whatsoever in there. For now I will keep this new option off and will contact my carrier for the support of the Axon and ZTE in general.
Hello,
I have read and found success making options for wifi calling appear in the stock menu when it was absent before, however the phone is nonetheless unable to make wifi calls after enabling. Tried placing phone in airplane and turning wifi on.... or just choosing the "wifi only" option for making calls in the network menu - Resulting message always states to connect to a wireless network to proceed with the call, even though I have an excellent connection and internet works fine.
I have done an exhaustive search for methods to successfully use T-Mobile's wifi calling feature on my phone.
My initial research revealed that the option should work so long as your phone supports wifi calling as well as your carrier.
The wifi calling option was absent (as well as VoLTE) on the stock ROM, so I had high hopes that a custom ROM which included the feature would allow me to utilize the service with T-Mobile (my current GSM carrier).
After a slew of unsuccessful attempts to make calls using wifi vs the mobile network, I finally called T-Mobile's tech support who was actually quite helpful, but essentially stated that wifi calling through T-Mobile requires the carriers own proprietary software to work... in other words, even though T-Mobile likes to promote the ease with which you can BYOD (bring your own device), it would appear that the wifi calling feature is only possible when buying a phone directly from T-Mobile unless a custom rom is built which is at least partially based upon T-Mobile's own proprietary software with regard to wifi calling.
If ANYONE has had any luck at all placing wifi calls on the T-Mobile network domestically in the U.S. using the global/MEG7 version of Redmi 5 Plus, your assistance would be immensely appreciated. I have found that, although my phone does not support multiple LTE bands used by T-Mobile, I am still able to make LTE calls quite frequently in my region using the single supported band.... however, my home is a "dead zone" so to speak and, even though I am smack dab in the middle of an excellent coverage zone, my service inside the house is poor enough that others' attempts to call are unsuccessful, leaving me unaware of the call unless a message is left.
At this point, I am getting ready to throw in the towel so any advice or success stories would be greatly appreciated - or, on the flipside, a validation that wifi calling is just not possible at this time so I don't have to drive myself crazy with a continued search for which a solution does not yet (or may never) exist.
Many thanks for your help!
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.
Hi so I recently activated the unlimited free text and calling from textnow on my samsung galaxy s8+ unlocked sm-g955u on their sprint network. When I had first done it I realized I was able to use free high speed data throughout much of my device with the exception of some games and apps it wouldnt work on.
So I set out trying to find away to bypass restrictions and limitations of the free data I had. I couldnt figure it out in the least, I tried everything I knew to hide usage. And in the process something horrible happened, I lost all that free data on everything except for the google search bar app. In which the google search bar you can search anything you want and all the results come up super fast. The catch is, I can no longer click any links and load pages beyond it. It just sits on a white blank page after clicking a link.
I tried to figure out what I did to change it or put their (I'm assuming) normal restrictions of data usage back in place where it was meant to be from the beginning. I havent been able to unlock the data since.. I e tried vpn like psiphon pro that I could use to get free high speed unlimited data from any captive portal login. But it doesnt work, rather textnow refuses to connect. Any sort of vpn textnow seemingly rejects the connection and I cant even place texts or calls.
I know textnow uses the sprint lte data service for its software. I know there is what I would call high speed lte data associated with my activated sim for text now. I can tell just simply by the load speeds of the google search bar reguardless of what you search for. That and what I had experienced when I first activated my sim and device.
So I'm coming here for a little help in brainstorming how myself and many other people who activated their own unlocked device in the talk and text plan, can bypass the restrictions textnow places on where the data can be used at. The data now is restricted to just textnow and google search (also nessecary functional apps) I know there is a way to hide this use of data, I tried the captive portal login which is speedy, but on pie i cant open the login into a browser to spread the service and i cant find a way to use the portal login to search anywhere else but textnow webpage.
Any ideas people? I'm sure many many people would benefit greatly to a loophole if any were found, and there is a loophole because my device was at first capable of near unrestricted data access before i tried to fully unlock it. If you know someone that might have some valuable input please tell them about this discussion and bring them here.

I realize this post is from last year, but I just ran across it and wanted to give my input in the event it may help somebody. As most TextNow subscribers are aware, T-Mobile's prior acquisition of the Sprint network is now geared towards shutting down the Sprint 3G & 4G networks nationwide. In fact, the lights have already went out on the former, while the 4G side is slated for complete shutdown by mid-2022. Accordingly, TextNow is presently migrating all subscribers over to T-Mobile's GSM 4G-LTE/5G nationwide network. Subscribers who were already using Sprint compatible devices are receiving free upgraded GSM SIM cards from TextNow to make the transition seamless. Unfortunately, this will likely be the end of all the free high speed 4G-LTE data subscribers enjoyed while connected to Sprint's network. This free data exploit was due to a proxy anomaly caused by the default reverse tunneling settings of certain brands and models of smartphones. While the knowledge will do little good now, the "restrictions" of using the data device-wide, across all apps and services, could be bypassed by setting up pdaNET+ on the TextNow device as host access point. Then, by enabling a WiFi direct hotspot via local proxy, the connection could be shared by a Windows 10/11 PC or laptop, by way of the pdaNET+ client-side setup. Then, by using the native Windows 10/11 hotspot feature, the data connection could be resolved and shared by other mobile devices in a normal device-wide manner. So while the TextNow host device would be unable to use the data across all apps and services, any devices connected to the Windows hotspot would have unfettered and unrestricted use of the data. Depending on how tech-savvy you wanted to be, the Windows PC Ethernet port could be used to traffic the data into a home router or extender for expanded sharing. Great while it lasted. I just recently received my TextNow GSM SIM in the mail, and haven't yet had time to experiment with data connectivity or exploits thereof. I will keep my findings posted here as I probe the uncharted waters .
So as you might or might not know, there already is a pseudo free data that is running on the google servers. Example: open a browser and search through google and you will get the results, its slow so I'm assuming its 3g. but they have a firewall that is blocking every other site unless its running via google servers.
You could theoretically setup a google hosted server yourself, maybe rent a cloud server out from google and run programs through there. run a tunnel through that for unlimited data on the phone. Someone just has to figure out how to do that.
For anyone reading this and wondering what we're talking about. Textnow is a free phone app you can use with their SIM/network and never pay a dime for phone service and texting, including media texting. It's totally free.
If this were to be more useful in terms of what sites we could visit, it would be a lot more lucrative.
Another idea I had, if someone has a pentesting rig that can run this network and see which ip addresses are being blocked, we could start building a list of sites that are whitelisted, both IP's and hostname resolved (http/s for example) this would allow us to see where we can start digging to find a place to setup a tunnel here.
I know that google has server hosting via their cloud computing network, you can even host DHCP style servers on it, so you could theoretically use this to tunnel through if the google server IP range is whitelisted. which it might be..
Google has an VPN that's free with Fi, so maybe you can pay for the VPN if you don't use Fi, therefore it's going through Google servers to then the user, so maybe if it costs less than TN's 1GB plan, we could consider it if it works.
