I think it worked really really good got me all the answers I needed to know about my phone..very satisfied thank u unlockbase.
Neat! Phone was unlocked much faster than expected. on 05/21/2022
ATT gave me a hard time when I tried to get my iPhone 13 mini unlocked through them. So I ended up putting in and paying for an unlock through Unlock base. I put in the request Thursday and an email arrived around Friday midnight saying they were able to get the phone unlocked and low and behold, the about section on the phone now says "No SIM Restrictions". This was a very pleasant surprise and much faster than expected. I can definitely vouch for this company!
