Which U.S. carriers have Touch Pro2 with GSM

Hi, guys.
I have been thinking of buying a Touch Pro2 from ebay, but got totally confused.
I need the phone with GSM support, and from what i could see, the ones from T-Mobile and AT&T have that. Then there is this U.S. Cellular carrier. Some sellers list it as GSM capable, but the official HTC website tells otherwise. And there are other carriers too!
Would someone from the U.S. make a little guide for me, please, on which carriers did provide Touch Pro2 with 100% GSM support?
Thanks a lot!

Well here's where it gets confusing - ALL RHOD's have GSM radios. Even the CDMA ones - they were sold as "world" phones, so they had GSM radios and SIM slots.
Now your question probably pertains to which frequency is supported, and for that you'll have to look up specs. GSM arena or something like that would probably have the bands supported. Make sure whatever phone you're buying supports the bands you need for 3g.
With that said, any RHOD will work... but will it work on 3g... I don't know. You didn't even say what carrier you want.

I am from Ukraine, so Quad Band GSM capability is preferable, 'cause if I'm not mistaken, our domestic carriers are 2G and use GSM 900/1800.
So, by saying that all Rhodiums have GSM radios you mean that I can buy a U.S. Sprint branded Touch Pro2 (which is listed as CDMA only, and which I like the most by its looks ) and can still use it on a GSM network? That's terrific news, even if flashing a ROM or a radio is needed, but... Are you ABSOLUTELY 100% sure about that?

I have a Sprint TP2, and it does in fact have a GSM radio/SIM slot. However, I'm not that familiar with the device and what bands it supports.
The RHOD400/500 is more desirable IMHO, because it has a dedicated 3.5mm jack for headphones .
Let me see if I can find official band info.
Hopefully this image helps:

I'm not that concerned about the phone having a 3.5 slot, as about it being capable to make a call LOL! Still, from what I can see at the official HTC website, only the T-Mobile and AT&T version do not have it.
Also, thank you for the link! The thread explains a lot!

None of the GSM-only variants (RHOD100, 110, 210, 300) have 3.5mm jacks. Good luck.

I was just in kiev and travelled to uman with a sprint touch pro 2. I bought a life sim card and it worked great. was making international calls on skype over 3g travelling 70mph and it was pretty decent.

7T VoLTE works, no Vowifi / wifi calling on Verizon

I purchased my 7T (model HD1905) online in October of 2019 directly from OnePlus. The phone is absolutely amazing and functions perfectly except it is not able to perform basic WiFi functions such as text or make phone calls. I work in the medical industry as a tech in a hospital laboratory. The laboratory is located in the basement of the hospital where I am unable to receive my carrier's (Verizon) signal. Hence, I am unable to use the aforementioned wifi functionalities and certain apps on the hospital's excellent broadband WiFi (2.4GHz / 5GHz). During this busy & intense time of the COVID-19 epidemic, the ability to effectively use my phone's apps and calling functionality over WiFi is vital and an absolute necessity.
In the past I have used an original Google Pixel (unlocked) and also my daughter's $60 (the cost a couple years ago) Samsung that I bought on eBay to flawlessly make phone calls and perform the functions that the OnePlus 7T is unable to achieve.
My question is:
Is it likely that OnePlus is going to roll out a fix for vowifi / WiFi calling for the OnePlus 7T on Verizon, the largest US wireless carrier? I see that Verizon now carries the OnePlus 8 having this desired wifi functionality and needless to say, I feel cheated. OnePlus is supposed to be synonymous with high tech and deemed as "A flagship killer". Will OnePlus develop a fix for the 7T's WiFi limitations / inabilities or should people that purchased a 7T resort to buying a $50 phone on eBay to fulfill the 7T's shortcomings? Though Samsung is more expensive, it seems overall to be fully functional on the majority of wireless carriers.
I appreciate any thoughts or insights.
Regards,
wantin2mod

I could only get mobile phone calls to work with VZW. No texting, and no VoWIFI. I am trying an AT&T sim for a couple of months to see if I can get service in most of the areas that VZW has worked in my area. I have not proven if VOWIFI in AT&T works yet, as I was not in an area with no service and Wifi yet. To me this phone is a total fail with VZW, but I think it is more their fault than OnePlus.

In a nutshell; The issue is with Verizon not Oneplus. The necessary hardware and software is on the phone, but Verizon hasn't authorized wi-fi calling for the 7 series, claiming security concerns, and it does not appear they will. Verizon allows Wi-Fi calling/SMS for the 8 because they sell a Verizon version of that phone; my understanding is that they don't allow wi-fi calling for non-Verizon branded 8's either.
You can't buy a Verizon branded 7T so Verizon has no incentive to allow the 7T to use that feature on their network. The alternative is to get a VOIP number from Google, Skype, et al and set up a SIP account under calling accounts in the dialer

For Verizon, you need to call them and enable CDMAless provisioning in order to get texting to work. VoWifi.... we are basically up ****s creek without a paddle. This is on Verizon and not a OnePlus issue as the 7t is whitelisted to prevent it from gettting VoWifi and LTE Video calling.
I fought with them for a week and finally was able to get them to trigger VoWifi, but there is something universally blocking this feature on Verizon's network unfortunately. They triggered and I even tried the logkit...no dice.

What about with MetroPCS? I have issues with WiFi calling as well. When WiFi is on it even tells me, "Mobile network is not available. Connect to a wireless network to make a call."

Question LE2120 unlock 5G EU Bands

Hi,
my wife bought a brand new Oneplus 9 Pro as a present for me from Ebay.
They say that is "European International Version", infact it runs Oxygen OS 11.2.6.6.LE15BA.
A few days after receiving the gift I asked my operator (Fastweb) to enable 5G because it doesn't Work. They say that 5G is enabled by default, so i inserted my SIM card in a friend's Samsung S21 and... all was ok.
After some research I realized that they had sold her the Chinese version that supports only few 5G bands (not the italian of course) flashed with the EU ROM.
Now the question is: it's possible to unlock missing 5G frequencies?
I tried to modify carrier policy.xml, but with no results.
Pls, help me.

No you can't, hardware (I mean including non-flashable memory) is completely different.

Completely different?

No you are wrong it is not hardware. All use same snapdragon with the same modem inbuilt. So it can be fixed.

Technically it's the same hardware, but the bands are baked into the baseband firmware and not user modifiable. Messing with carrier_policy isn't gonna change that. Unfortunately OP is SOL, hopefully it's still a good 4G device for you. Here is from mt-tech (author of the qtsp article)
This instruction only allow enable/disable 4G Carrier Aggregation & 5G EN_DC combinations and band support if hardware support it. If hardware doesn’t support, you can’t enable/disable band. Example OnePlus 8 (China) 5G doesn’t work in USA even it support n41 (T-Mobile/Sprint) band because it doesn’t support 4G anchor band used in USA.

We see this all the time, where Chinese OP devices are sold by 3rd parties cheaper but does not support everything and then people complain.

And it's possible to flash a different baseband?

The "baseband" you flash (non-hlos / modem.img) should be treated more like a driver for the hardware you are running. Technically it's more complicated than that since it handles the low level modem stuff prior to Android. There is no (known?) way to modify the actual firmware by the end user.

Oh... I remember that on the old S3 it could be done. If the hardware is the same we could try.
But it pains me to think that we have been scammed, that my wife threw a month's salary away and that I find myself with a neutered device.

Sorry to hear that, hopefully it's within the seller's return period. It's usually a caveat emptor kinda thing, the listing will usually tell you exactly which base model it is and the bands listed. If the seller misrepresented the device as a LE2123, then you can probably dispute it. Otherwise, most sellers offer a return period with a restocking fee.
AFAIK, the older device's modem img is actually the entire baseband and not non-hlos, so it can drive the entire modem.

First of all thanks for understanding.
So, do you know where to find the img and how to flash?
In the meantime, I try to contact the seller: luckily I haven't removed the protective plastics.

The Global ROM (AA) has the global non-HLOS, EU (BA) has theirs, etc. You can extract them from the OOS full update images, but like I've said, it's not gonna make a difference.

Hum... I will try.
Do you know if there is a standard procedure to do this?

I had LE2120 Chinese on AA version, no volte no 5g

In the first post you can find my modified subscriptions.xml, but i think the problem is at the firmware level.

Are you getting 5G in Zain KW? Even I get 5g in preferred network type. But when I select the option, I see the same image as highlighted. there is no option to select 5G

Just to clarify, i see this:
but no 5G connection in signal status.
Once again: i'm in 5G zone and my operator (Fastweb IT) supports 5G by default for all customers.

This is the result of scan. As you can see, no 5G networks can be found.

Question Volte on Oneplus 9 Pro. Is it a carrier thing?

Hello,
I am having troubles activating Volte on my OnePlus 9 Pro.
After a chit chat with OnePlus support, they told me that my country carrier needs to support the Volte option for Oneplus.
Apparently they say my carrier doesnt have Oneplus in their list of smartphones that support Volte.
I managed to find a list of smartphones that my carrier has for Volte and it was only made of Samsung and Iphone.
Is this true? Am I incapable of running Volte because my carrier doesnt have OnePlus phones in ther list? OnePlus isnt popular at all in my country.
So, if this true, means even if i force turn on Volte on OP 9 Pro, i still wont get it to work?

OnePlus is also not on the list of supported devices for my carrier but I still managed to make it work on my 9 Pro following the guide previously mentioned.
Give it a try and you might be surprised of the output.

did your IMS appear as not registered first? Were you using LE2120? because they also said it can also be differences in frequencies for the countries.

LE2120 and IMS was "not registered".
After forcing the display of VoLTE/VoWifi toggles and changing the configuration in PDC to "Volte PTCRB", it started to work on my phone (logo in the status bar and "HD" indicated in call history)
My carrier is Viettel and I live in Vietnam.

I'm with T-Mobile and I have the OnePlus 9 Pro from the OnePlus store it's not T-Mobile specific I went with T-Mobile because they're 5G is better and AT&T didn't get voice over LTE at all. I went on a prepaid plan because there's no taxes involved my wife and I both have unlimited everything with 5G and I think we pay 80 bucks a month. I downloaded the version one OnePlus log kit switched on volte and vo Wi-Fi did the reboot and you can see from the screenshots when I don't have LTE vo Wi-Fi kicks in and when I don't have the other v o l t e is always active and they both work all my calls are in high definition. The carrier did nothing for me it was that simple I'm not rooted and I'm on the stock software... It's great because even if I have a dead zone I can make phone calls and send and receive texts over Wi-Fi no problem it might be worth looking into going to T-Mobile just for that feature especially when it's prepaid plan and you don't have to pay all those taxes! Good luck I'm so glad I got this phone I had just bought the OnePlus 80 and the charging port was getting bad on it so I went all in and got the nine Pro!

It works you need to turn it on in the settings so that you see the icon but to be sure just make s phone call if it changes to H+ or 3G then you don't have VoLTE

VoLTE and WoWIFI works natively on T-Mobile with the US model, T-Mobile model or from Oneplus themselves, so those extra steps were completely unnecessary . It's 100% carrier dependent, you just happened to be on a carrier that supports it.

So i guess, even if i do all that with PDC, i will still not be able to access VOLTE right? Because my carrier only supports samsung and iphone for now...

Assuming PDC is your carrier? Then correct. If they only whitelist Samsung and iPhones for VoLTE, then that's what you need to use.

PDC is a program that allows you to force activate volte on your phone. but thank you. i kinda got an idea now.

Same here (in Ukraine) guys. Oneplus 9 Pro doesn't support VoLTE, though previous older phones did!
Can changing of Profile in PDC affect VoLTE? Or only carriers can affect this? How do they Whitelist our model?

PDC not work on Android 12 ?

USA market VoLTE with 3G deprecation: are Xiaomi phones usable (10T Lite, in particular)?

Hi,
I'm in the USA using Tracfone. I recently purchased this phone (end of last year).
I rooted it. I installed the Sakura ROM. I had an understanding that there might be "some assembly required" with a custom ROM & I am mostly happy with it.
But recently I have started getting messages from Tracfone, "Tracfone: Your service is at risk! Your phone will stop working 2/22.".
This appears to be coming from the underlying carrier, AT&T, and relates to the 3G deprecation. VoLTE is supported by the phone and in the ROM but it seems this phone is not in AT&T's whitelist of allowed phones after 3G deprecation. This seems to be related to supported bands (this phone supports a great number of them but perhaps not ones useful to connect to AT&T).
Are there any workarounds for this? I could get a T-Mobile SIM from Tracfone but I am guessing I am going to have exactly the same problem from them?
Can any of these phones even be used after the deprecation of 3G has been done by all the major carriers?
Am I missing something?
I would love to be able to actually use this phone.

Ouch. Didn't think that would happen so fast.
I actually double checked to be sure my phones are white listed by AT&T.
See what other carriers say because I don't think there's a work around for AT&T especially if the bands aren't supported.
Maybe advanced tech support would have a suggestion or fix you could use. Some of the agents will go out of their way to help, some are duds. As always use Google search...

well afaik, you've only got 3 options
1. spoof the imei and make it look like a supported phone. not sure if i can talk about the specifics here and even if i could, it'd be a pita even for me to do it
2. find another carrier who doesnt whitelist phones
3. use voip apps like google voice to bypass the volte problem

Don't think the first option would work because it's the configuration and/or hardware that's the problem not the brand.
AT&T makes big bucks selling cell service so I doubt they turn down your business if your phone was compatible.

I checked the T-Mobile IMEI checker and, if it's accurate, it doesn't look great. I'm not sure what "not blocked" means but it claims it's incompatible.

Not blocked may mean it can be used for data only or it's not blacklisted?
What's it say for the expanded explanations?

well most xiaomi phones dont really work too good over here in the us because of missing bands with the exception of the mi mix series.
this pretty much explains the situation

I ordered the T-Mobile SIM from Tracfone. I figured that worst case was that I am down $1.00 & will be left without a working phone (until I have access to an old backup phone in a few weeks that will probably work —Moto G6 Play); vs. by default being left without a working phone in a few days if I did nothing (until I have access to the old backup).
It looks like it was allowed. The only hitch was that transferring my phone number (from using the AT&T SIM to using the T-Mobile SIM) took a bunch of hours. I even have VoLTE enabled (which appeared not to be possible with the AT&T SIM —and I assume is the only way this phone will work after the switch, if at all).
I imagine the coverage may be spotty given the poor coverage in the supported bands but I may be OK with that for now (probably depends on how spotty spotty really is and where). I'm sure it might be one of those YMMV things (and one that could change in the immediate future?).
