I bought a Samsung galaxy z flip 5g off of ebay. The seller said it was unlocked, but when I got it in the mail it was locked to ATT stating it would be locked until installment payments were done. I gave the imei to unlockbase and maybe 2 hours later they gave me the unlock code and now I can use my carrier(t mobile) with no issue! This is great! Unlockbase was also the cheapest option I found!
