OnePlus 8T+ 5G 256GB - Green - Unlocked

it is an unlocked OnePlus phone that is compatible with Verizon. but I cannot order a SIM card for it because my IMEI shows up as incompatible on the compatibility checker. I talked with the help center and when they checked it says I'm compatible. they told me to order a SIM card but I tried over and over only to get a messagethat it's incompatible. why am I told it's all good when I can't order a SIM card to make it work? both techs I messaged with said it should work..

it's unlocked yes, but it was not advertised as an old T-Mobile device. That's pretty disappointing.

It’s T-Mobile locked but everything works fine and phone still works normally, battery is not good overheats when charging overall still a good for the price

This phone should have been listed in "Flawless" condition, because I do not see a single knick or scratch that should have dropped it down into "Good/Fair". Works perfect, looks beautiful, cheap as heck, what more can you ask for?

Phone was supposed to be UNLOCKED so I could use it on Verizon and it's LOCKED TO TMOBILE AND I CAN'T UNLOCK THE PHONE EITHER. THIS WAS FALSE ADVERTISING AND WAS LIED TO.

First time using BackMarket. Incredible job by BackMarket. It was in excellent condition besides the scratch on the camera glass, but everything else about the phone looked perfect. Definitely going to be shopping with BackMarket again.

Great phone, amazing delivery, only took about 28 hours from order to arrival. Charger complete crap (15w instead of 65w original). Why do they do that?!?! Anyway, happy. Still to test battery capacity.
