I bought a ulefone through them and it came to me locked. The seller did not understand why that is a problem. They would not or could not supply an unlock code, so I had to spend and extra $29.00 for the software to unlock the phone. AliExpress didn't understand the problem, so they took the side of the seller and offered zero help, no refund, just a lame excuse that they sell many phones. I even offered to return the phone at my expense, but still no refund. The seller is ULEFONE Official Store. Warning! AliExpress is a full scan. You will have no legal refund if they stick it to you.
