Vzw LG G2 VS980 Global SIM Card Problem - G2 Q&A, Help & Troubleshooting

I have a Vzw LG G2 VS980 that I currently use with Red Pocket on the Vzw network, and I previously used it on Tracfone, also on the Vzw network, and everything worked normally.
I also successfully used it with Red Pocket on the AT&T network as well as with an old Lycamobile legacy SIM, using the T-Mo network.
The problem I'm having is that I can't get cellular data to work using a Piranha Mobile or FreedomPop Global SIM card.
There are no error messages displayed, and I'm able to make voice calls with the Piranha Mobile SIM card. The FreedomPop Global SIM card doesn't come with traditional voice service, but there are bars of service showing.
The APNs are correct:
For Piranha Mobile, I'm using openroamer.com .
For FreedomPop, I'm using freedompop.foggmobile.com .
The Vzw LG G2 VS980 is rooted, but running stock 5.0.2. I rolled it back to stock 4.2.2, but cellular data still wouldn't work with the above SIMs. I also tried a custom ROM, and still nothing.
Can anybody suggest something to try to get cellular data to work with the above SIM cards? I'd greatly appreciate it!

I should also add that I DID enable global roaming in settings, and I did play with all of the System select>>Network mode settings, to no avail.
Also, even if people reading my question don't have an answer, if you could suggest some way to contact someone that could help, I'd be very grateful. Thanks again!

Isn't there any help available for my issue? Thanks.

I sure could use some help in figuring out how to fix this problem. Thanks!

Did you ever figure this out? I am experiencing the same problem

Unfortunately, no.
My LG G2 also was difficult to get activated on Vzw MVNOs. I used it on 2 Vzw MVNOs, and both times, it wouldn't activate the SIM card properly. Both MVNOs had to do quite a bit of work to get it to activate properly. There was no issue with the ESN/IEMI, it was just that the hardware wouldn't activate the SIM card properly.
Not only that, my LG G2 VS980 developed dead spots on the touch screen in March, 2017. It's still usable, but the dead spots make it difficult, so it is mostly retired now.
Oh, well...

I'd try getting into your G2's phone "diagnostic" menu (or whatever it's called), and doing a manual band set. That seemed to help me when I put in an AT&T SIM in my vs980.
It could also be that FreedomPop or whomever you're trying to use doesn't support the network bands that the vs980 uses.

VS980 on GSM Question

I bought a VS980 (The Verizon G2) because they come unlocked and it was cheapest. I use Net10. The sim card works within the phone, however it constantly shows that i am roaming, i dont get hspa+ (4g) anymore. Also it shows the sim card icon with a question mark on it. Could i possibly flash AT&T firmware onto it to fix that? I mean, what could i do? What specific things would i need to change?
Thanks a lot!

i also face same problem always showing roming icon when i use any gsm sim card on it...
I have the VS980 and it works great on T-Mobile, I get GPRS, EDGE, 3G, HSPA+, and LTE. I never tried it with AT&T or another GSM provider though.
When you use the stock ROM it will have issues like you listed, however if you install another ROM it should work fine. I believe I was running Malladus 4.2.2 at the time which removed the ? icon, and I didn't have to enter any APN info. I also ran it when on a 4.4 AOSP ROM.
so do i have to downgrade the bootloader or what? I'm actually trying to get a verizon vs980 on cricket (aio wireless/at&t network) and can only get H speeds. not bad and i can stream HQ youtube videos without buffering but would like faster. any input?
I met this problem, too. Is there any solution so that I can get my 4G back?
Please help.

VZW G2 error that I can't get rid of (No service, select network unavailable-AT&T)

VZW G2 error that I can't get rid of (No service, select network unavailable-AT&T)
So I was playing around with my LG G2 in order to test the GSM functionality of it (I maybe traveling in the near future), moved the mode from Global to GSM/UMTS, told it to scan for networks here in the US and found AT&T and T-Mobile 2G & 3G (I live in a re-farmed major metro area). I selected AT&T to see if it could connect with the VZW SIM card in the US and obviously it couldn't (authentication denied). Now I have a problem I can't get rid of: I put it back on Global mode and everything with the CDMA/LTE mode on VZW works but I have a message in my task bar of of the following:
No service
Selected network (AT&T) unavailable
I rebooted the phone and cleared the warnings and it still stays after reboots.
Right now I'm thinking the only way to get rid of it is to insert an active AT&T SIM card and let it run on AT&T. I don't have one right now but I can get one from someone in the family.
Would this help in clearing it?
It's really only a minor problem. It would really only be apparent if I needed to service this phone in a VZW store or send it back to VZW.
And yes the software/firmware is updated to the latest version.
Look in apns and delete non vzn

Someone with a little more experience tell me what I'm doing wrong here please.

This is probably something silly and small but I'm pulling my hair out trying to fix this. I bought a G4 play XT1607 unlocked from Best Buy the other week. I also purchased a tracfone SIM activation kit. The kit had 2 sim cards, one GSM and one CDMA. Since I used Verizon service previous to my foray into prepaid plans, I activated the phone with the CDMA SIM card and registered the IMEI with Tracfone. Then I was able to successfully unlock the bootloader following the motorola official procedures, put on TWRP and flashed a LineageOS ROM w/ SU and OpenGAPPS. It worked fine for a couple of days and then *poof* my internet data would no longer connect at all. I rebooted several times and got nothing.
I then saw that there is some LTE/wifi handoff bug and I figured, no biggie, I'll swap my tracfone service to the GSM SIM and pop it in and it'll be good to go. Not so. At first, in fastboot, the screen was saying <Baseband not found> and I couldn't even place a phone call. The phone still doesn't seem to recognize the SIM card and doesn't show any cellular connectivity. I've tried flashing AOKP, LineageOS (both 7.1) and the stock 6.0.1 deodexed several times. I've tried this thread here and using it's 2.35-1 Radio file with the above ROMs which I installed using TWRP as well. None of this is seeming to work so I called Tracfone and they said it should be working and must be on my end. So following this I decided to go fully to flash fully back to stock. I used this file:
https://mirrors.lolinet.com/firmware/moto/harpia/official/RETUS/
and followed these directions
https://forum.xda-developers.com/g4-play/how-to/guide-return-to-stock-firmware-recovery-t3551797
Phone seems to be working fine other than not getting any kind of cellular signal. Even though it should be "factory fresh now" When I called tracfone they didn't seem to sure of themselves and told me it would activate within 2 hours and to call back if I had issues. It's been 4 hours now an dNo sign of signal. Did I mess something up here? Does tracfone need to do something on their send since this phone/IMEI was used previously on their service as CDMA? Or can I just "pop the new SD card and go" Or do I just need to add something like APN settings or similar to get what I have working? I don't want to call tracfone again if I don't have to because they didn't seem to know what to do when I explained it to them and sounded incredulous that one phone did both CDMA and GSM to begin with.
Can anyone help me? I'd like to use this GSM SIM card in my unlocked XT1607 (RETUS). This phone was previously on the same tracfone account with the same phone number but on their CDMA network. What gives? Is this something I messed up or tracfone needs to deal with?
I did some more research and I'm pretty sure this is on Tracfones end. I believe they still have it registered as a CDMA device and it's ignoring my GSM SIM when I turn it on.

I don't think that's the issue. Did you set an APN for Tracfone? With the GSM SIM, you have to configure the APN.
Tracfone's site says to go to apn.tracfone.com but that site gives an error. I did find this: http://apn-settings.com/tracfone-apn-settings-step-by-step-configuration-guide/
Or you can check on Howardforums or Turks.
Also G4 Play, also Tracfone BYOP. I, however, did GSM from the getgo to avoid something like this. On my phone, when I installed Lineage, my MEID disappeared entirely (it only shows my IMEI in settings). SIM card reads just fine and APN settings are fine. I do think the initial ROM you installed inhibited the device's ability to read its own MEID (everything hints at these ROMs being made specifically for dual-SIM GSM phones). However, switching to the GSM SIM should have worked, provided you actually transferred your number and didn't just pop the other SIM in (the MEID on the Red "BYOP" card would have needed to be decommissioned).
Here's a thought: Try dialing *22890 on the phone. If it says the phone is programmed for CDMA service, then that could be part of the issue. Also check Settings to see if you have both an MEID and IMEI, or just an IMEI. If your IMEI is 0, then the SIM Card is not being read and they need to ship you a new one.

No Global Network Mode

I have a factory unlocked S8 I just recieved that I've been using on Straight Talk(verizon network) and that's been working fine but I wanted to test the reception of t-mobile in some places and I can't get anything to work. I have a Flash Wireless sim that I've used to at least see if I have service on other phones but I get nothing on the S8.
In Network Mode I only have the option for LTE/CDMA or CDMA. No Global or GSM options are even listed. Does this have to do with the SIM card not being properly registered? I would think I would have a Global option regardless of SIM I put in it.

I have the same problem. I'm on MetroPCS and I bought a Galaxy S8 used on Straight Talk before. I can't make any phone calls, but I have LTE and SMS works just fine. Does anyone else experience the same issue? I really appreciate any help. Thank you.

? Using LG V20 H910 AT&T Model On T-Mobile After (2021) VoLTE Change

I posted this ? on reddit as well; however, this device is on its last legs so there's not much interest for it. I've gotten some good answers here and there on this website, but a dedicated thread to gather all the good info might be more helpful.
I still use my AT&T H910 as I don't really do much gaming on it. Calling, texting, and YouTube is what I mostly utilize it for. I just heard about the whole VoLTE requirement on specific devices after 2022 for AT&T, and 2021 for T-Mobile.
I spoke to AT&T, and they re-assured that the H910 was going to be one of the devices supported after 2022; however, I've been thinking about changing to T-Mobile (my family has a great plan with them, and I always switch back and forth between carriers based on who gives me the best deal) but I can't seem to get a straight answer from T-Mobile about whether my unlocked H910 will work with them after 2021; some didn't even know about the 2021 specifics of it.
I know AT&T will have to allow devices to be used on their network after 2022 even if they're VoLTE capable already. By the looks of it, T-Mobile won't go to that extreme; however, does anyone know exactly how VoLTE works? Specially in regards to using the AT&T H910 model on T-Mobile? Does my H910 has the required Bands to utilize VoLTE on T-Mobile? Or is it one of those things like "Wi-Fi Calling" where T-Mobile Wi-Fi calling only works with the LG V20 model from T-Mobile, and AT&T Wi-Fi calling only works with the LG V20 model from AT&T?
You need band 12 support which H910 has. Also a rom with IMS services working so no AOSP roms.
Volte works by using IMS processes in the rom to route phone calls over IP. No volte = no phone calls. But the device will still "work".
In theory the ATT software will work, unlock it and borrow someone else's sim. In theory a partial cross flash (just system, no modem/aboot/etc) could work if it doesn't.

I was recommended to use an app called Network Mode Universal on reddit for VoLTE testing purposes, and after inserting a T-Mobile SIM card that I borrowed on my unlocked H910 and using the application, the Voice Network Type tab says "LTE". Which is supposed to be a sign that VoLTE might be working on the H910 using a T-Mobile SIM, but that's all I know; just what people tell me.
Update:
The person who recommended that Network Mode Universal app forgot to mention that you have to actually make a call to know whether the phone supports VoLTE with the SIM card in use. When actually making a call, the Voice Network Type tab changes from "LTE" to "UMTS". Which means the H910 is not VoLTE capable on T-Mobile.

Could also be how his sim is set up. Volte has to be enabled there and in the phone. My suggestion would be to force LTE only on the device as well. Does it use VOLTE on his phone?
Also look at IMS registration in the phone and see if it's registered.

The person I borrowed the T-Mobile SIM from uses an iPhone on iOS 13. According to him, the option for turning on/off VoLTE from the settings is gone. He used to be able to turn it on and off at will; not anymore after iOS 13. It should be enabled by default on an iPhone though, I don't see why it would be off. It's almost a necessity on an iPhone I would think.
The LG V20 seems to be more limited in that sense, as on my previous Samsung phone I could enable 2G, 4G, LTE, etc, individually to force only one. I don't see any of those settings on my H910. I don't see any IMS info either.
Either way, I doubt T-Mobile would bother servicing my AT&T branded H910 phone in case IMS needed to be registered; in the case that it wasn't already. I've had really bad luck in the past dealing with T-Mobile on phones that are not T-Mobile branded.

IMS has a phone component and a sim component.
you can check status in the service menu of IMS on the H910. Hope it works on my Tmo phone, getting my sim upgraded

It should work if it's a T-Mobile phone. The H918 is 40% more expensive, so it would be great if the H910 worked with T-Mobile; however, it's not looking good.

Eh, kinda. I'm having trouble too. My IMS services aren't connecting. Going to try a few different roms. I'm through an MVNO so still trying to get them to understand ISIM vs USIM.

Gotcha, I hope it works. I was mentioning to @C D which has helped me understand a lot about VoLTE, that I'm starting to give in to the system of using whatever carrier my phone supports, as long as I can keep using my H910. The removable battery & IR blaster era has come to an end, and I don't think I need another phone right now other than the V20. I might even consider going back to the AT&T MVNO I was using before.

Latest result: oreo works but not nougat.
IMS never registers. Maybe I can fix it. At least now OK sim-wise. Unfortunately doing the sim swap broke tethering.
Hi guys, I am sorry for reviving the old thread.
I too owned H990DS Sea version on latest nougat. It has volte option but just couldn't switch on.
Please take a look at this thread on LG G8
https://forum.xda-developers.com/t/...ther-qualcomm-powered-lg-devices-too.4343655/
I tried on my H990DS using the above thread's method and it didn't work. I was informed that the mbn files are for LG G8. We need mbn files that are specific for LG V20. I have searched up and down and I couldn't find any.
So I hope that I have provided some insights and I hope any member/master/guru out there can help where to find the mbn file (collection of all international carriers mbn) and make volte works for H990DS.
