I just received a "replacement" for my "HTC 10 Unlocked" phone yesterday. I was surprised to see they had included the SIM and SDcard trays...I opened them up to find a 4GB card with "HTC" and "Java" printed on it - interesting. Then I opened up the SIM card tray to find a Sprint card. I'm a T-Mobile user, so I'm worried that they may have sent me a model that's somehow less compatible than I had before.
Q: How can I tell if this phone is SIM Unlocked? (Note: I only have T-Mobile SIMs)
Q: Is there any other difference in the so-called CDMA version 2PS6500 and the 2PS6200? Did they remove any of the GSM bands or anything?
Q: Is there any easy way to confirm support for Band 12 and VoLTE?
Thanks!

Q: How can I tell if this phone is SIM Unlocked? (Note: I only have T-Mobile SIMs)
You need to cross-check by trying diff GSM / CDMA-based carrier from your friends / relatives / colleagues
Q: Is there any other difference in the so-called CDMA version 2PS6500 and the 2PS6200? Did they remove any of the GSM bands or anything?
Yes there is difference I believe , CDMA version will support GSM bands (upto LTE) & but GSM model (2PS6200) I guess WON'T support CDMA networks..
refer pocketnow.com/2016/04/01/htc-10-fcc
Q: Is there any easy way to confirm support for Band 12 and VoLTE?
Yes support for FDD: Band 12 confirmed from htc.com/us/go/buy-htc-10 page
Not sure to confirm VoLTE support but you can dig the VoLTE option under Settings -> Call ; If you don't find under it then its not there..
You can also visit respective country tht you are living (assuming USA )in this case htc.com/us/go/buy-htc-10/ & scroll all the way to down for Specs -> Network
& guess what I'm dying to get my hands on 2PS6500 which will be best of both worlds (GSM/CDMA) cuz here in India we get only 2PS6200 model variant...

I want to use VOLTE in korea, So I have to know my htc 10(unlocked ver) support TTA VOLTE CODE.
Does HTC 10 support TTA VOLTE??
TTA VOLTE is code which makes VOLTE available.

You need your firmware and your carrier to support it. Unlocked model of HTC 10 supports VoLTE. If your carrier does then you are good to go.

I already know unlocked htc 10 support after nougat. But I searched , To use VoLTE in korea I need some code(or type) in firmware.
My carrier (Sk telecom) doesn't support international VoLTE code(type). They use their code not international code.(I don't know exactly).
International VoLTE include all VoLTE types? If yes, then I can use VoLTE.!

If your carrier doesn't support VoLTE, then you won't be able to get it. I'm on Telus in Canada with a US Unlocked device. US Unlocked supports VoLTE, but my carrier only supports it for the newer iPhone models. So I don't get it and you won't either, unless I/you change carriers or our carriers decide to support it. Sorry, but that's the way it is.
EDIT: I misread your post. And don't understand it to tell the truth. VoLTE should either be supported or not. If they don't use International/WWE code (?) then try US Unlocked firmware instead.

As someone who lives currently in Korea and understands this issue on a very real level (lolㅠㅠ),
most carriers in the world use a VoLTE standard defined by the 3GPP. What Google claims regarding baking VoLTE into Marshmallow is according to the 3GPP standard. This is why I can buy a phone in Spain and take it to Germany and use it no problem (for the most part).
But Korean carriers established their own VoLTE standard called TTA-VoLTE before 3GPP could create an international standard. So any phones bought in Korea likely won't work with VoLTE abroad, and vice-versa (save for some exceptions).
In terms of carrier, the key exception is LG U+; since their network depends exclusively on LTE and CDMA, for BYOD customers (해외구매폰) they have to support the 3GPP standard on top of the TTA-VoLTE standard (see link below). There are some success stories of people taking their Hong Kong phones and using it on LG U+, their LatAm Samsung phones, etc.
In terms of phones, iPhones and some Google phones, some Sony phones (flashed with Korean ROMs), and some LG phones supposedly support TTA-VoLTE (check 2nd link).
My advice? If you have the phone with you, either take it to LG U+, see if they can register the phone as "OM-Phone" (Open Model), and see if VoLTE works; or just live without VoLTE as I have been doing for the past 2 years (ㅠㅠ).

Outside of the iPhone which is a "special case", AT&T has been known to only provision VoLTE and/or WiFi calling for users of AT&T-branded and sold [Android] phones; however, every once in a while, they make an exception for a particular model (e.g. / famously, the Pixel 2).
In the case of the M9, both the AT&T-branded (locked or unlocked) and unbranded, factory-unlocked models share the same HTC model # (OPJA110). I have also noticed that if I take a clean IMEI from an unbranded model and run it through various AT&T IMEI checkers, it almost always returns a positive result, as though this IMEI exists in AT&T's database. But if I take, say, a clean IMEI from T-Mobile-branded M9 (OPJA120) and run it through the same checkers, they say this isn't an AT&T phone (which would be correct!).
So this raises the question: in order to achieve VoLTE on an M9 on AT&T, do you absolutely have to have an AT&T-branded model? Or has anybody had success with getting AT&T VoLTE working on an unbranded, factory-unlocked M9? That an unbranded phone's IMEI passes the AT&T IMEI checks would *seem* to suggest that AT&T might treat *all* OPJA110s as AT&T devices, not just the ones that happen to have their logo printed on the back.
(I realize that if you have an unbranded phone, you may need to change CID and flash the AT&T firmware on the phone to get VoLTE to work...my question is solely about people's experience with the AT&T/network-side of the equation. An unbranded phone with an AT&T CID and software should be functionally identical to an AT&T-branded phone, but the question is whether the AT&T network will refuse to provision VoLTE for one's SIM/account because they don't see the phone as an AT&T phone based on its IMEI.)
Thanks!
Like title says, can I put a dual sim tray in my 9 pro north american LE2125 to get dual sim?
as far as i know, only the telekom model (le2127) is not a dual sim device

Hi, I have an dual sim card tray in my unlocked NA model, the same model you are referring to. i bought it (dual sim tray)off of Amazon from a link someone posted quite a while back when android 12 was first coming out. There was a thread here with the info at the time. I haven't ever got to use the other sim because at the time they had a few uncertainties. I'm still on a android 11 based custom ROM.

It is? Strange, my sim tray is only a single sim, my ROMs only show 1 sim number. And yes, my phone model IS LE2125 and not the T-Mobile version. I have used the LE2125 msm numerous times and global OOS and never had issues with modem/base bands and stuff so my model is the north american global unlocked

is your device perhaps a telecom device (telecom devices are only single sim) which has been flashed to a global device?

No, even if it WAS flashed to global, I would have to use the T-Mobile msm, which I don't need or use. Also, don't have radio issues using custom ROMs like T-Mobile users have.

No, LE2115 and LE2125 are both single SIM. In fact the T-Mobile LE2127 is a dual SIM device, one of the reasons people were buying it, but it's totally unstable, as it ships with a single SIM tray and the second is disabled.
I received a couple days ago from Amazon my order for OnePlus 9 Pro 5G LE2123 Dual SIM 12GB+256GB EU/UK Model Global ROM Factory Unlocked International Version. After setting it up and done migrating all my files from my OnePlus 8 Pro Model IN 2025 Dual Sim, I am surprised to see that the item I received is the Model LE2125 which is confirmed Dual Sim.
My previous research all said that Model LE2125 is only Single SIM, but here is my newly delivered Model LE2125 and it is indeed Dual SIM and both SIM cards are confirmed working. Can anyone enlighten or confirm that LE2125 is actually not Single SIM?
My primary TMobile card on Sim 1 is working fine and picking up 5G, while my secondary international roaming card on Sim 2 is also working.
Your feedback and input will be appreciated. Thank you much.

So, LE2125 is single sim ONLY. I know because I bought a dual sim tray and put 2 active T-Mobile sims in it and only 1 showed up.
But mine is LE2125 and I was surprised to see that it is in fact DUAL SIM, with dual sim tray and both sim cards are working (I put in my primary US T-Mobile sim in tray 1 and my international roaming sim card in tray 2). I bought the device from Amazon Marketplace used or refurbished.
Please see the 3 screenshots I posted showing the ModeLE2125 with 2 Sims and 2 IMEIs in device settings.

I think your software may be LE2125 but its either T-Mobile hardware or EU hardware.
Thank you for your kind observation. But all I can say is that this LE2125 is DUAL SIM with dual sim tray with 2 sim cards working (even my international roaming sim card on sim 2 receives my multiple test sms mesages sent from my US Tmobile number). So, as a hardware this LE2125 is working fine. As far as its sotware is concerned, it's already beyond me how it got into the device.
Thank you anyway for your input.

What I am meaning is, you phone might actually be LE2123 or LE2127 with north American OOS showing LE2125. Software is not hardware specific. Some ROMs will change your model number
Thank you so much for this info, that software is not hardware specific. This info is very new to me as I thought all along that frequency bands on a device is dictated by the physical hardware itself and not assigned via mere software configuration.

It's not the bands that are being spoken of, it's the hardware model shown in the settings. If you have a full conversion device, it's possible to convert from, say, LE2127 T-Mobile to show LE2125 US unlocked instead.
This is likely what happened because T-Mobile devices sell for cheap because nobody wants to deal with the headaches from them.
Thank you for this valuable information. I thought specific device models made for let's say, Europe, China, US have the radio hardware baked in with specific 5G or 4G LTE bands that work in specific regional markets.

They DO have this. Changing your model number with software won't change the bands that are supported, it just can change the model number (which is incredibly stupid as it makes it easy for people to sell a phone as something that it's not).
Wow, thank you again. Yes, it looks like it borders on deceitful practice although it is not illegal.
if u wanna be absolutely sure which model u're getting, check the IMEI number against online database.
it will show u exact model.

I have LE2125, & i can confirm that it's a single sim device.
though i always if there's any way to make dual sim work in this model.
