SeconHand phone carrier lock
I buy a second hand iphone, and after swtich on, i discovered that the sim is lock from Carrier. Now I want to know if this phone is clean or have some issue between the old owner and your company. ...
You can check the IMEI checker over on Swappa for starters.
Whether it is clean or not, T-Mobile can only SIM unlock devices for T-Mobile USA customers whose accounts and devices meet all of the SIM Unlock Policy requirements.
