tmobile version actually unlocked? - OnePlus 6T Questions & Answers

hey guys i have the tmobile 6t and pay for it monthly on tmobile
i unlocked it and put latest 9.0.11 oxygen os on it
does this mean I can use it on ATT or verizon? I'm not sure if its actually sim unlocked without finding someone elses SIM in there. I know i had to sim unlock to unlock the bootloader but will I still be able to use it on verizon or ATT or another tmobile account?
thanks!

If you flashed the international's ROM, it's now SIM unlocked.

I read in the unlocking thread that flashing the international rom allows the bootloader to be unlocked, but not the phone itself. I don't have a different SIM to test my theory, though.

You must request a Sim unlock from T-Mobile. If you did the recent msmtool where you flashed to international version of oos. You would need to reflash with msmtool for tmo in order to request the unlock Sim code. Using the msmtool to flash international does not Sim unlock. That is done through the Sim unlock app installed on tmo 6t os. And must be requested and approved by Twitter for the unlock Sim code. Which you can do through TMobile Twitter, higher success rate

Are you sure because I've went to a sim unlock website and they said that verizon cannot be sim unlocked with a code. But other carrier models can.
Yes it can't be unlocked because it is already unlocked from Verizon

TMobile Software Download?

Is there a way to get the newest version of TMobiles Oneplus 6T software downloaded on my device? I have the TMobile variant now and I need to use the Unlock app to unlock my phone because I just finished paying it off. The TMobile software comes preloaded onto the device but now I no longer have it. I wanted to know if there is A. a way to download the Device Unlock TMobile app or B. downgrade to a TMobile software version. I turned my device into an international version.

TMobile to intl on Metro?

Ok, so I've successfully don't the TMobile to international (without unlocked bootloader) trick to unlock my bootloader. My friend wants me to do the same with his, though I just realized he is using his with MetroPCS. Will this method still work? Or should we apply for token to do it? Model number is the same as my TMobile version.
It will still work.

Unlockboot expensive, but do you recommend?

Hi,
I found that "unlockboot" can help me to unlock my S10+ SMG-G975U, that previusly UnlockUnit identify my device as Unavailable - CDMA and something like that topic.
Do you recommend unlockboot to unlock by 99USD?
Thank in advance!
Are you wanting to carrier unlock it or bootloader unlock it? The phone is already carrier unlocked, just insert your SIM. The bootloader cannot be unlocked on the G975U.

Hi,
No, there is a message that said "Sorry, your device canĀ“t be activated on another carrier's..."
What carrier are you on? If you flash the U1 unlocked firmware and insert a SIM, it should work. If you don't want to flash then it looks like you need an unlock code, which is odd because from what I have read the G975U is already carrier unlocked.

Thanks, I will try to flash U1 fw. The cellphone is Verizon, and I am looking to move to Movistar (Telefonica) of Mexico.

Wait wait. So you're saying my Sprint S10+ is already unlocked? Just need to flash the U1 software?
If you purchased a carrier branded model new it doesn't normally come unlocked. You need to own the phone outright before a carrier will unlock it and some carriers require that the phone be used on their network for a minimum period of time (usually 1 or 2 months) even if you did purchase it outright from them.
You cannot flash U1 firmware on an S10+ unless it's carrier unlocked.
Hello,
I flashed this one: https://forum.xda-developers.com/s10-plus/how-to/sm-g975u-firmware-downloads-tmo-spr-att-t3908657. Everything goes ok, and the message of unlocking appears, requesting me the unlock code.
Any suggestion?
Thank you!

Actually you can flash U1 firmware anyway, but it will still be locked to the same carrier without the unlock code. Carrier locking is IMEI based, not software or device based.

Have you tried calling the carrier and asking them to unlock it? Most carriers will unlock your phone once you've had it for 3 months.

Recently the firmware for the S10+ became all-inclusive like on the S9 models so I'm not sure if flashing U1 firmware over carrier firmware will get rid of the carrier apps anymore. They seem to get installed now automatically as part of the provisioning for the installed SIM card. If you have a network unlocked Verizon phone and insert a T-mobile SIM you end up with the T-mobile boot animation and T-mobile apps and all the Verizon stuff is gone. Maybe the U1 firmware doesn't work the same way.
I read in a different thread that you have to activate the phone with Verizon and wait 3 days. After that just put in another carrier SIM and the phone should auto unlock.

this is incomplete and some is inaccurate..
his vzw device doesnt need to be paid off but does need to wait 60 days from activating on the verizon network before they unlock it..
also you can absolutely flash u1 firmware on a u device, it has literally nothing to do with the sim lock.. and no, flashing u1 on u doesnt magically unlock the sim..
pretty sure on U firmware vzw device will say message cannot be used on another carrier yet.. on u1 will i believe prompt for unlock code when a dif. carrier sim is inserted
https://www.verizon.com/about/consumer-safety/device-unlocking-policy
sprint however needs to be fully paid off and active at least 50 days and account needs to be in good standing to be eligible for sim unlock

are you trying to unlock the Sim or the bootloader? i have the same phone and was disappointed to find out i couldn't unlock my bootloader. no root no custom rom smh. but it's because Samsung removed the developer option to "oem unlock" which must be enabled to unlock. so done online service claiming to be able to do so is crap and waste of money. also if you're trying to unlock the Sim which I think that's what the site is claiming to be able to do because Sprint is a CDMA network if you unlock the SIM the only other service you can put it onto would be boost or Virgin Mobile which just use Sprint's towers. they're the only network still using CDMA. so pointless all the way around sorry buddy.

Thanks for your reply!
I am trying to unlock the sim, the cellphone was Verizon US, (refurbished by asurion). And wanted to use Movistar (Telefonica, from Mexico just GSM). I am searching to do a root and try to follow this guide: https://forum.xda-developers.com/showthread.php?t=1693491. So what I understand, the site "Unlockboot" could do a CDMA unlock, and after 3 days of chatting with the person that is on service there, sounds that are possible, also is possible that I can continue using my GSM provider of Mexico. But it is very expensive 99$ USD is 2000$ MXN... Also, I do not trust a web service, also if there isn't a reference on this forum.
So that's the update...

you are wrong.. U variants will work on all us carriers once sim unlocked.. its been this way a few years now..

I think ibowtoandroid who maintains multiple Samsung device threads on XDA has an unlock service but I'm not sure what he charges.

Where I live there are multiple independent phone shops that sell SIM cards and phones and are not affiliated with a single carrier and also phone repair shops that offer to SIM unlock a phone as a walk in service. You can probably find a shop to do it if you don't trust an online service.

VoLTE in the US on the International version (McLaren) (T-Mobile)

I was wondering if VoLTE works on the international version of the McLaren edition in the US. I need the dual SIM model and as far as I'm aware (I asked an associate, actually), the T-Mobile version does not have a second SIM slot.

Theoretically, if it's anything like the 6t all you need is a oem dual SIM tray off eBay

There's a bit of process getting that to work, assuming there really is a hidden second SIM slot. Considering how new the phone is, I'd rather not risk bricking the phone trying to change the ROM to get the option of a second SIM slot to appear.
Thanks for the reply, though.
You can use a 2nd sim tray once you root & flash international firmware but the IMEI will be the same on both.

When I unlocked & rooted the 7 pro TMO version both IMEIs were the same. I'm assuming the same with 7t McLaren. But I'll know soon enough, I've requested unlock.
