IPhone 11 retailer space grey

Product Name: IPhone 11 retailer space grey
This was retailer used on a t-mobile line but from what i understand it has been paid off and can be used on other carriers?. PLEASE READ!!!!!! This was a messed up iphone 11 Irepaired it but some things just didnt work i replaced -the housing of the phone -the screen -Case -the battery which is why the battery notification pops up... apple doesn't like third party repairs -whenever the housing came in the buttons didn't work which is why im putting the price lower, the power, volume and silent switch dont work or click which is why i have assistive touch on the screen. Wireless charging doesn't work either The face id works perfectly as well as the cameras, everytging like wifi conections and speackers work well too and the phone Isn't i cloud locked Im not sure if it has any other little issues but This is 100% all the information i know about this device... mostly because it was a cousins. I have put more than $200 of repairs into this so in the end Ijust wanna get a little something back.
