Using the GSM radio on CDMA Touch Pro2

Has anyone pulled this off? I need to use the GSM radio on my CDMA/GSM Verizon Touch Pro 2. Booting either the CDMA ROM or the GSM ROM, neither can see the GSM radio with the SIM card inserted. Frustrating I appreciate all the work you all have done so far!

And for what it's worth, the port is amazing. I can boot up, use wifi and otherwise enjoy a great phone experience (sans radio of course).

Did you remove force_cdma from your startup.txt? I haven't tried it, but I'm pretty sure you can get the GSM radio working.

So playing around with it more, I can get the radio to work part of the time but it's very inconsistent and I can't reproduce why sometimes it works and sometimes it doesn't. I did remove the force_cdma bit as well.
Also, on this model, any attempts to use the GPS immediately crashes out of Android (i.e., Google Maps or even Google.com mobile where it tries to geolocate).
Has anyone else had more luck? I was pleasantly surprised that for an hour last night the radio was on and in roaming mode. I didn't get data working but that could have been due the particular SIM. Still, potentially promising.

I can confirm 100% certain now that this will NOT work if you use a Verizon handset and roam using the included Verizon SIM card. The GSM version boots fine, but Verizon requires seeing the CDMA ESN to authenticate over the GSM network. Since this rom does not acknowledge the presence of the CDMA side of things, the ROM will not get data. Also the GPS definitely does not work in this configuration and crashes out.
You *CAN* use a non-Verizon SIM successfully, but you won't get the goodness of Verizon's unlimited global data using their SIM, which is a killer deal for those that roam outside the US.

[Q] 3g gps not working htc tilt 2 with t-mobile

hello All,
I got a AT&T HTC touch pro 2 (tilt 2) from my friend who had got it unlocked from AT&T as he got upgraded to a new phone. I am using a t-mobile prepaid on the touch pro 2. I have got couple of issues with it.
1. The UI responds very slowly.
2. The data connection icon displays E. When I called up the t-mobile customer care they response varies a lot. One says i need to unlock the device from AT&T and others says i will be able to use only Edge as its not a device provided by t-mobile.
3. The GPS doesnt seem to work. When ever i used Bing. It says that its not able to connect.
I have a request is there any customisable rom that would help in over coming these issues.
Regards,
Mahesh

Same here, but other way round
I have a T-Mobile TouchPro 2 I've been using an AT&T SIM in, and I can tell you exactly what's up- The ROM is probably trying to refresh stuff in the background and it's not working because it's expecting an AT&T SIM. Try another ROM. As far as 3G, not gonna happen. T-Mobile's 3G runs on different bands than the AT&T 3G. The T-Mobile SIM wouldn't even start up the phone if it wasn't unlocked. And I think the GPS settings might be wrong, try fiddling around with the COM ports in Settings, but make sure you make a note of what they were before. I'd recommend a custom ROM, not to solve the problems you speak of necessarily, but it runs a lot faster, and won't have all the AT&T bloatware that's kinda useless to you. Oh, and if you don't have Connection Manager setting everything up for you in your ROM, make sure you set your APN.

Tmobile troubles with minutes/txt.. help?

Hey guys,
I was using my dinc2 in Europe all year and it was great. No troubles there.
I did some research since i've come back to US, and learned that people have been able to use tmobile with their phones. I've only read about some troubles with data plans ... but i'm not trying to use data at all.
I simply want to buy the 1000 prepaid minutes for 100$ from tmobile and pop it in. My plans is to use Wifi with google voice (groove IP) pretty much everywhere, and use the minutes from tmobile only when i'm on the move.
I tried getting a friends tmobile SIM to work just to make sure that there would be no problems, and i failed. It simply doesn't recognize the service.
My phone is S-OFF, hdboot .97, clockworkmodded, and runs Skyraider Zeus.
Is it a matter of running the correct ROM?

We have 2 DI2 and running both AT&T Prepaid and T-Mo Prepaid on it - no trouble with voice with Skyraider Zeus v1.3 or Nitsuj17's Stock Sense rom - APN settings for AT&T was auto-updated as I recall and being provisioned with a data bundle in the plan, it works. For T-Mobile, there are no default APN settings under GSM mode pre-loaded, but as you know, it's not required for voice & SMS to work on the DI2, you will get a "redirect" screen if you launch the browser to sign up for a data plan for it to work (and, that's indication of a working Sim card)
With the sim inserted & switched over to GSM, does it identify the "T-Mobile" network on the lockscreen or homes screen at all? after a reboot ? If you're running SR Zeus in Europe - then, there's no reason for it to not work here in the U.S.- recheck your settings for Mobile Network ...

LG G710ULM UNSUPPORTED VoLTE ?!? (Straight-Talk US - T-Mobile network)

*********UPDATE********** I bought a new sim from straight talk and VOLTE works now! (GSM compatible Straight Talk Sim card) My old sim was from 2014, so it wasn't VOLTE compatible.
I have an ebay zombie LG G710ULM flashed to latest Google Fi Android 9 software, I received an email from Straight Talk (Wal-Mart US cell phone service reseller) telling me that my LG G7 does not support VoLTE and my phone will be unable to receive calls in January 2021.
-Using a network info app, the app is telling me it is connected to T-Mobile towers (so I have a Straight Talk T-Mobile compatible SIM)
-I can't find any options to enable VoLTE in settings, and wifi calling is erroring out
I was wondering if there are ways to get VoLTE and Wifi Calling working (Straight Talk supports it, but not my current ROM/SIM).
I can switch to the following sims supported by Straight Talk.
-AT&T Compatible Sim
-Verizon Compatible Sim? If my phone supports CDMA bands
OTHERWISE MOST OF US WILL HAVE A PAPERWEIGHT IN 2021!!!!!!!!!

Same problem
I'm having the same problem. Any progress on this?

I'd like to know this too. Surprised there is no traffic here with all the knowledgeable people on this forum.
G710EAW here. BTW There was an Android 10 update just two hours ago from Android 9. Someone with an 'EM' phone in another thread said VOWifi is "working now" but how do others know if it's working when January 1st comes around?

If you guys have cross flashed roms, then volte will not work. It doesnt work for any of us who have crossflashed. Whichever model.
You need to be on original software. Looks like some licensing thing that volte requires. They need to provision volte for all the phones. Sounds like they are not interested to provision it for g7. Odd that even EAW model which has original firmware, they sent that mail too....
Sad/Odd to see your carriers are suddenly changing to only Volte.

Is there a way to put it back to original software? I actually don't need it crossflashed to anything because it's a Verizon originally and I would like to use it on that network. Or does it not work that way?

Main issue is that your carriers dont want to provision volte for your G7s. So no guarantee if cross flashing back to original will work.
There is crossflashing guide in guides section with which you can go back to stock firmware. Do this at your own risk.
In our country we have a volte carrier called Jio. They provide an app called jiocall. Using that app you could use their service even if your phone is not volte capable. You will have to see if there are such apps for your carrier. Thats the only non technical, simpler solution.

I have some information that might make all of you guys happy.
I was told by Safelink Wireless that VOTLE is a function of BOTH the phone *AND* the sim card.
Basically, if the phone itself is VOLTE compatible but the sim card is not, then the phone will be reported on their system as not compatible, and will ask you to upgrade your phone.
However if a VOLTE compatible SIM is inserted, if the phone does in fact support VOLTE, it will then work. That's because it's provisioned on the carrier via the sim card itself.
If you purchased a sim via the "Buy your own sim" package, e.g. online or from Best Buy, etc, awhile ago, then that sim is not compatible. You simply need to call Tracphone/Safelink and ask to buy a VOLTE compatible SIM (which costs 99 cents). Then when you get it, call their tech department to have them transfer the phone service and phone number to the new SIM.
You can dial the phone's service menu and go to the VOLTE/GPRI menu and if the options are there, then the phone supports it.

What's the correct service menu number for our phones?

Question Unlock version from Google on AT&T in the states

I'm wanting to get the Pro in black with 256gb storage but need to know if anyone is using any unlocked version from Google (not carrier branded that had be unlocked) on AT&T network and getting volte with calls. My company pays for my work # and just gives me the SIM to use in my own phone since I don't want an iPhone that they provide. I currently use a Huawei Mate 20 X and have that SIM working along with my personal # that's on T-Mobile (dual sim phone). Unfortunately due to AT&Ts whitelist any calls made/received on that # switches to 3G, this will make my current phone unusable after they shutdown 3G this Feb.
TIA for any info

I have an unlocked 6 pro on att and I think volte is working but don't know how to verify. I know wifi calling is working which was an issue with my previous unlocked phone

Unlocked Pixel 6 Pro user with ATT here. The wifi-calling works perfect, and surprisingly the visual voicemail is enabled. It seems to work just like an ATT-based phone without the bloatware. Odd thing is you cannot change the mobile network. Read somewhere here the ATT disabled this setting for some reason when connected to their network.

HD Voice (AT&T version of VoLTE) works perfectly well, as does WiFi calling, provided of course your account is provisioned for such.

Thanks, good to know. Currently with my Mate 20 X when on a call with the AT&T line the network switches from 4G lte (when not on a call) to 3G (when on a call) then back to 4G lte after the call has ended.

@Vash369 - thanks for sharing your feedback. does your unlocked P6P support dual SIM, e.g., physical sim card and an e-sim?

I'm not who you asked, but I believe all the factory unlocked P6Ps support dual SIM via a discreet SIM card and the built-in e-SIM.

Yep it does. It shows this in Google's spec sheet page. Mind you I'm only using physical SIM. So I don't know if both will work at the same time

Another unlocked/rooted P6P working fine on AT&T here. I just sim swapped from my old phone and it worked right out of the box.
