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.

Anyone try this? Windows Phone on Straight Talk?
Mobile data (internet) works perfectly fine (and fast!) but I can't connect to live services . . . which kills the user experience of a Windows Phone. The Live services work over wifi, but when there is no wifi connection, the services, including marketplace, bing search, scout, etc simply refuse to connect.
Any thoughts on how I can correct this? I've tried everything I can think of and spent hours searching to no avail.
Any help is much appreciated.
Hi, I have the Lumia 800 on Straight talk and everything works perfect.
Make sure the apn setting are good.
Is Straight talk a network that gives you SIM card and no phone?
If it's a network that uses some other carrier's masts i.e. O2, Vodafone for example, then there is a solution to it.
How do you get your APN settings on your phone? Do you enter it manually?
Here is what will help you:
Once you connect to wifi to do whatever you wish and you complete using wifi, go to your network settings, mobile settings, then edit apn - enter your APN settings manually. I am not sure what Straighttalk APN settings are but you would surely find it somewhere.
After saving the APN settings, restart your phone but make sure wifi is switched off before you restart.
After the restart you will be able to use Live services with 3g.
However as soon as you reconnect to wifi, you will have to re-do the whole cycle each time in order to get Live services working on 3g again.
This might or might not work. I had exactly same issue on giffgaff. I have spent 3 months trying to figure out, flashed ROMs, hard resets, swapped carriers etc and finally have found this to be the way it works. I own a HTC Titan. Till today I thought, it was HTC's fault because I have ruled out carrier and MS for this. But if the above works for you then, it clearly isn't HTC's or carrier's fault but sure OS that keeps forgetting the APN. The reason this happens is because Straighttalk in your case and Giffgaff in my case, DO NOT have APN settings stored on their SIM cards. The OS doesn't seem to be configured to remember it. Ideally when you swap from wifi to 3g, your OS shouldn't have to read your SIM. However WP in current state seems to be reading SIM everytime you swap from wifi to 3g. However, when it can't find anything on the SIM i.e. APN settings, the live services won't work.
If this works, please please please drop me a PM as I don't use this Lumia forums at all. I have a Titan, so I wouldn't know. But if this works, I will have to write to WinPhone Support with whom I've been conversing for about a month now!!

Mind sharing what settings you're using? Also, are you using WP's built in APN tool or Nokia's Network setup?
APN is: att.mvno (all other fields are empty).
Using the built in WP APN under cellular in settings.
Tried the Nokia but it messed up the phone so I took it out.
Let me know if this helps.
I'm using my 800 on StraightTalk and have had the same issue. I found there are essentially 3 places where the APNs can be set up, and reboots must occur at the right time. (Win settings, ##634#, and Nokia tool)
it seems to be overly sensitive as to how they are configured. I must have reset this thing at least a half a dozen times before getting it to work. Ultimately, I ended up with the settings in all 3 places, but the sequence I did it in is Win Settings (network APN), ##634# (both network and MMS settings), a reboot, and then download the Nokia tool via WiFi and use it to enter the settings there for both network and MMS followed by another reboot. That issue is most definitely related to the APN settings, but I'm not quite certain why I had to do the hokey pokey to make it work. None-the-less, I hope this helps a little. Once you get it working, it seems to stick through reboots, wifi, or pretty much anything except swapping out the SIM card, which hosed everything up again.

Interesting. . . There doesn't seem to be anywhere to do that in the most up to date version of the diagnostics tool. (I know they changed a few things in the most recent update.)
I may have to restore to a previous version . . .
Thanks

I just activated my Straight Talk SIM yesterday (I was on T-Mobile's EDGE connection) and used Nokia's Network Setup tool to add, and make current, a new APN with att.mvno under the Internet APN's 'name' field. That's all I did, and data works fine (surprisingly, even on the RM-801 which doesn't have AT&T's 850MHz band).

How is call quality and what are your download/upload speeds. Been debating whether I should get a RM-819 device which is harder to obtain than a RM-801.
OK, I cannot find this information anywhere so maybe someone here can help me.
My wife bought a Galaxy S5 and we had quickly paid it off. Because we only get 2G where we live , we decided to switch to Straight Talk.
After a week of Straight Talk not working correctly (we would have Full LTE service but could not make or recieve calls) we then ported to Cricket AIO.
We are having the same issue and don't know where to start. I wiped out the factory image and installed a debloated Rom thinking removing some
T-Mo junk would help but it doesn't. Everything is correct, APN settings and all. Can somebody shed some light and let me know what to try next?
Thanks
Try *#2263# from the dialer and select GSM networks instead of automatic.
Let us know how it goes.
I am currently using a t-mobile galaxy s5 on cricket without any problems.
Using the stock rom (rooted) I have a cricket SIM card in the device. I booted up the device, went to settings, then more networks, then mobile networks, then default setup and chose automatical. Then, I chose the automatic network option. You could always use the search now option and manually select AT&T.
Next I added the APN. The cricket website has them available so you can manually add them, but I actually had a little icon pop up that let me install them automatically.
Either way, correct APN is essential for texts and LTE.
I then downloaded titanium backup and manually removed t-mobile bloatware. I then downloaded the cricket apps that were recommended (cricket sent a text with the apps when I inserted the cricket SIM)
Finally, I edited the build.prop to say the device is a cricket galaxy s5. I think I changed it to model klteaio.
Other than the boot animation (which I could change if desired) this device is now identical to my Cricket galaxy S5 that I also own. It even says cricket on the top bar like the Cricket branded device. As a matter of fact, the back cover and the startup animation are the only way I can tell the difference between the two.

You may want to consider using an app called LTE discovery from the app store to ensure you have lte as an option. I have found that selecting the WCDMA/GSM option instead of the default LTE/WCDMA/GSM under settings-> MOBILE NETWORKS -> NETWORK MODE sometimes provides better service on cricket when the LTE signal is poor. This will turn off LTE, but leave 3G, 2G, talk services enabled.
Good luck.
Zero Lemon was the issue.
After a bunch of testing, I figured out that the zerolemon 8,500mah battery seemed to cause the issue. When we put the original battery back in, calls worked just fine. I tried again with the zerolemon and calls failed.
Thanks for reporting back. I wonder if your extended battery pushes too much load on your device.
If you happen to pop-in the lemon again, put this code in your dialer and let us know what Voltage reads your getting.
Also mention the battery's charge level at the time.

I am attempting to switch my Verizon GS4 handset to Straight Talk Wireless, but I can't do anything to change the APN settings. I restarted my phone multiple times with the ST SIM in the slot, but it continued to connect to Verizon's network. Some research later, I found that I needed to change the APN to Straight Talk, but I can't.
Only Verizon's LTE access shows up in the menu. There's a + button at the bottom, but it's greyed out, with either SIM (tried both as per this HTC One thread). Pressing the menu softbutton gives me the "reset to default" option, also greyed out and inoperable.
The phone is rooted, still running Jellybean 4.2 MK2 because once I rooted, the OTA updates would fail, and I was never brave enough to try Safestrap. I'm worried this might be part of the same break.

In my experience, IT DOESN'T MATTER!!!
I do NOT mean that in any disrespectful way to you, but I DO mean it in a way against Verizon and Tmobile.
I have the same phone AND the same problem with service; however, I CAN add an APN. The catch is IT STILL CONNECTS TO VERIZON!!!
Now, my phone updated to the utter crap that is Lollipop, and I can no longer get my call-Verizon-voicemail-and-disconnect workaround to work as the connection is a lot more seamless and does not drop/fully disconnect after the call disconnects. Before, I'd goto my notifications and see "NO SERVICE" in the bottom of the slide down box with my VZW voicemail notification with it's 10 voicemails. Then, I'd do my workaround and everything would work (and, by everything, I mean text messaging as voice and data WERE working pre-workaround). But, like I said, now I can no longer do that (Lollipop SAYS it's connected to Tmobile off the bat (right after booting up); however, I CANNOT send text messages NO MATTER WHAT I DO!!!
It's completely aggravating and how Verizon can say they sell a phone "UNLOCKED" when their APN is in there with other APNs and GREYED OUT so you CANNOT REMOVE IT (which, as I've shown above, causes massive problems) and how Tmobile can say ON THEIR SWITCH WEBSITE that my VERIZON SAMSUNG GALAXY S4 *WILL* WORK on their network... it's all beyond me. It's deceptive/straight up lying marketing and the way Tblowbile always tells me they cannot support my phone and to buy a new phone WHEN THEIR OWN WEBSITE SAYS IT WILL WORK is 100% bait and switch and up for a class action lawsuit!
Update: it does appear my service with the ST SIM really is through my Straight Talk account now, despite what the APN settings show. I got my device activation text from ST. This makes sense, since Straight Talk is a virtual carrier buying airtime from the real networks like Verizon.
However, I don't have an LTE connection. I don't have any data connection, just voice and SMS. I'm not sure if that's a problem on my end or the carrier's, but getting the data I'm paying for is less of an emergency than not having any mobile communication.
Has anyone found a work around for this. On straight talk, I can get calls and even internet when set to global network. I cannot text either sms or mms. My APN setting completely grayed out. I can not add or change existing and tried an apn manager with no luck.
I suspect I'll have to flash a completely Verizon-less build to fix it, but I did have an ST representative call me to ask if everything was working and offer to try to help me fix it. I just didn't have time right then and they didn't call back when I asked them to.
Just my experience
Hey not sure if this will help anyone out but I'll add what I've experienced. I have a gs4 running hyperdrive and my data service from straight talk has cut out a couple times before. The first time I just waited, and it fixed itself after a day or two. Second time I called ST and they told me to restart my phone (like I hadn't done that 10 times already). Later that day, data randomly comes back. I noticed that the fix for me was to switch apn settings. Somehow my phone did it automatically. But now my data is MUCH slower than before. Straight talk seems to be a tricky company. You never really know what you'll get with them. Just other carriers' sloppy seconds. Cutouts also seem more common at the end of usage cycles. Seems a lot of people fix it by calling ST
Also, I can edit my APN. Not sure if it's because I'm on an aftermarket ROM or what. But now I'm on the hunt for an APN with better data speeds if possible.
Straight Talk APN
It took me 3 months of calling Straight Talk and telling them they needed to send the right APN settings to my phone, after they finally listened it took 2 minutes until I received a text saying they updated my APN settings. I had the exact same problem as you. I had voice and SMS but not data. And my APN settings were greyed also. Now it says
Verizon Internet
TFTWO.GW9.VZWENTP
You just have to get them to update the APN. Getting them to listen is the hardest part! I hope this helps!
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:

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.
