T-Mobile OP6T dual SIM question

I ordered the 6t from T-Mobile website and will have the phone next week.
Would really like to see what we can get with the dual SIM difference. Is it just the SIM holder that's restricting the dual SIM or is the actual circuitry different.
If it's just the holder, then flashing the global room for the 6t should enable the dual SIM functionality.

From what's been said by others (And confirming myself with the T-Mo model in hand), there is only one IMEI number assigned to the phone, and thus I doubt the dual sim functionality can be made to work at all.

Also... As some mentioned in the other thread... We can't flash the global ROM on the tmobile device.. There's some specifics to the modem that can't be changed.

Dual SIM might be an issue but custom rooms/ports based on then global version will not be an issue at all once bootloaders are unlocked after the first month.

Can someone with the 6 see if the dual sim tray will fit the 6t and pop in two Sims that work on the T-mobile network? This worked with other phones with single imei so it might work here too...

True, but that doesn't mean that we can't flash a new radio once these devices start getting unlocked.

You should be able to flash the unlocked version of OOS once your device is unlocked from T-Mobile

We should be able to but the official line atm is that due to modem specific changes the global version cannot be flashed on to the tmo variant..also due to this the tmo variant won't be included in the Oxygen is beta releases..lastly ppl are saying that the tmo variant doesn't have a secondary imei for the 2nd SIM slot that is disabled/not present..in order to confirm any of this we need a tmo variant bootloader unlocked..we likely won't see any developments till the 2nd month of the phones release.

You're phone is SIM unlocked from T-Mobile..to unlock the bootloader u need to request a token unlock from one plus before u can experiment..which they say will be sent after requesting in 7 days..or did OnePlus already send u the bootloader unlock token. SIM unlock is simply one requirement in order to request the bootloader unlock.

If the phone isn't locked to T-Mobile I don't see why it can't be changed it would be treated as any other unlocked device

What about the the new 600Mhz crappy spectrum (Band 71) on Note 9 is a joke not FULL LTE only 4G and like -500db this is absurd so I need to know if the T-Mobile version is only software (modem) or the change something to the CPU or wait to someone extract the modem of the T-Mobile version and flash it to the Global Dual Sim and done.

Without knowing location I can easily assume that:
1.) -500dB means you are stupid far from a tower that's using said band
2.) ...because you're so far from said tower you will not get optimal speeds

Use the app Cell Mapper & look on your desktop PC for the site with the same name.
It'll give you a look at where each band is deployed.
Band 71 is still sparsely in use, I'm guessing less than 10% of all T-Mobile towers have it

I already use few ones to check it. right now I using OP 5T with T-Mobile and Att (dual sim) honestly with T-Mobile got few hiccups on the road here and there I do test with both but the Att Signal is strong all the way I ever go with T-Mobile I got HD Voice and voLTE (no need buy the phone from theirs the services are SIM Card provided) but Att have it if you bought a branded phone from theirs.
I will wait few months more I don’t think T-Mobile will stand near Att yet.

Is it worth buying the international version of the s10 plus

As far as do you guys think it will have a decent rom and kernel development section? Because the only reason I would buy a international version is for the custom Tom and kernels and mods. Thanks In advance!!!
Sent from my [device_name] using XDA-Developers Legacy app

yes - there is already some development in the S10 threads for compatible mods for our phone ...as twrp is updated and installation simplified, there will be even more development.

I have the international version and find that I have been getting software/firmware updates much sooner than they come through the US carriers.

I am based in the USA, using the international S10+ on T-Mobile. I bought it from Clove Technology in the UK (very good service). It was for the same price as the USA model at the time (pre-order time-frame). My phone was delivered in NY the same day the phone was publicly released in the USA.

Alright thanks for your response.I'm on T-Mobile as well. What kind of download speeds do you get on a speed test out of curiosity using the international model on T-Mobile network I'm just curious thanks in advance for your reply take care my friend.
Sent from my [device_name] using XDA-Developers Legacy app

I'm not really up on the specifics, but from what I understand the international version lacks some of the LTE bands used by some carriers in North America. Also, some carriers apparently disallow volte and wifi calling under certain circumstances for foreign esn's.
Worth exploring further if you're buying from overseas and those kinds of things matter to you.

Yes, it's worth it. Rooting makes the phone better. You get better audio with viper4android, custom roms and customization. You get more control of your $1k phone
Using att on my s10+ exynos. Lightning speed here in Beantown

Not sure if it depends on the phone, but I'm using Google Pay and Samsung Pay (through my Samsung watch) on my rooted Pixel 3Xl. I'm able to do this by hiding root in Magisk.

This depends on your coverage. I did do a side by side test with a T-Mobile 6t, and my international S10. We were getting similar speeds side by side.
The fastest I've gotten is 110 Mbps. Which is similar to the LTE on my previous devices. Even with CA on a 6t, you get the same or similar speeds. The only difference right now for me, was my service on a call while driving. I had a little connectivity issue while on a call recently ( just breaking up here and there).
Also, it may depend on your CSC if you have Carrier Aggregation for certain bands enabled. My XSA does not.

If #benchmarklife is your thing, then each to their own, thats cool. I like to game and the Exynos game lag experience is real. Plus the Qualcomm 4G/wifi modems are the best in industry.
I also disagree on battery life, I've done a side by side comparisson with the Exynos and SD855 - using them the way I use a phone and my SOT was around 6hrs for the SD855 and under 5 for the Exynos. I would love to see your battery stats getting 8-9 hrs SOT, because, cough, it seems, cough, a little bull**** to be honest.. :laugh:
Here's a good comparison between the 2 handsets, I fail to see how the Exynos is better than the SD855 S10+. But thats ok. Im sure your own benchmarks show a different story :good:
https://www.anandtech.com/show/14072/the-samsung-galaxy-s10plus-review
For me, ultimately, the biggest issue with Exynos in Australia is that wait for carrier firmware releases.. And I'm glad I don't have that wait. The G9750 seems to be around 1.5 months ahead of the carrier releases here for the Exynos.
Ultimately the S10+ whether Exynos or SD855 is an awesome handset. Samsung did real good :good::good:

Ok nps

Is it possible for Dual SIM on T-Mobile without flashing international

Does anyone know if it's possible to get the dual SIM working on the T-Mobile version? Im fully unlocked I just don't want to go through that whole process
I only need the second SIM for data only on Visible if it matters (it's a long story as to why lol)
Thanks

No, it's the only way. Converting to the international version is easier than you think, and it's really worth it, believe me.

I can agree. Soon as I could I converted mine to international back in November/December 2018. Best decision ever for this phone

Bought a used Tmobile 6T at a phone shop in Vegas, converted it the next day, unlocked, rooted, debloated, and put google on a leash. Worth doing!

Can I use a new tmobile op6t with att after I sim unlock and flash intl version?

I use AT&T for my carrier.
I'm trying to understand if I can use a brand new OP6T T-mobile version - https://www.oneplus.com/oneplus-6t-tmo?from=6t - on ATT. I had presumed if I follow the guides here to SIM unlock and flash the international version, that would allow me to use ATT (without ever using, talking to, or becoming a customer of Tmobile). Is that the case?
If not, can it be done at all (dual sim tray? 2nd imei?)?
Thanks.

If it is Sim unlocked, it should work fine, but why buy a T-Mo phone if you won't be using it there? Instead buy the global version.
I routinely see posts here from folks using the T-Mo version on other carriers and having issues, or troubles from flashing the international OS version.
Also if there is an issue with the unlock and you aren't a TMo customer who knows what the resolution path would be.

T-Mobile OP6T phone is currently on sale on the one plus website for ~$350. I don't believe new global versions are that cheap though I haven't looked yet (was about to). Thanks for your reply.

Trust me. Spend a bit more for the global phone. There are all these issues with converted phone's not passing safety net, Netflix not showing, Google Pay not working depending on what OS version you are on... It isn't worth the savings you might get.

TMobile versions don't have a 2nd IMEI, they only have one. The second sim slot has the same IMEI as the first one.

Flash IN2020 to IN2025

Do we have a clear, step by step on how to do this? I've tried flashing the IN2025 firmware via local update but it still shows as In2020 with disabled camera.

Might want to back up your persist partition before you do that. May break it

Well yes, but I'm trying to get it to flash to IN2025. It's just not doing it.

Flashing software does not change the hardware. You're on an IN2020, and OOS will report as such even when you flash intl OOS.

So essentially, there's no way to get it to re-enable the IR camera.

If the phone does not support your radio bands, changing the firmware to the unlocked Global FW won't enable them.
If your carriers radio bands are supported by the IN2020, you may need to add their band combos as per this guide:

He hasn't changed the hardware, he has changed code to trick the phone to get the photochrom filter back, this will not work on band's for 5G

i have a Photochrome option when i use my camera, does that mean that it's still in though.

Yes if the option is there you will have either a phone that isn't IN2020 or 21 or if you do you have one of those phones you aren't running the latest firmwar for that phone.

Where To Get This Model EDL Mode Firmware , One Plus 8 Pro China (IN2020)

My understanding of 5G support by these different phones is in the link here, https://drive.google.com/file/d/1mgz7Z6TADnXZgpCdCoLeRHX22wC_vLq8/view?usp=sharing . I am currently in the U.S. and a T-Mobile customer but planning to move to Europe one of these days. Though T-Mobile only supports the n71 band today (not supported by IN2020), it will be rolling out the n41 band (supported by IN2020) soon with the merger of Sprint. On the other hand, n78 (supported by IN2020) is quite common throughout Europe. With that said, the Chinese Model, IN2020, seems to be the best compromise if one travels extensively. It overlaps with the European bands over several different frequencies and one US band that I know of (n41).
Unless of course you are an AT&T customer, then IN2025 is the only way to go because they use n5. In this case, you won't get 5G coverage while you are traveling internationally (except on n41 in China) because the US 5G is just so different than overseas.
None of these models support mmWave, and these phones will become antiques first before mmWave is ubiquitous anyway. If even fingers can attenuate the mmWave signal, we are talking about at least several transmitters on every city block to make it practical! That said as of 2020, I wouldn't spend extra $150-200 USD for a phone that supports mmWave. Google's new Pixel 5 could have been $150 cheaper without it.
Other than the radio compatibility, I can't really think of a good reason to convert an IN2020 to IN2025. If I'm missing something, please enlighten me.
The method described by Whoareyou sounds very interesting. I may try that one of these days.

Here's my story.
I got my OP8pro in China, and once it's in my hand I flashed it from H2 OS to Oxygen OS. Through the past two years my model was showing as IN2020 with no issues until I saw a Beta version of Android 12 Oxygen OS. I flashed it and the model turned to IN2025...I googled the difference and that's how I get here.
