Hello!

I found an IPhone 4S and after a week of trying to find the owner decided to go ahead and unlocked for T mobile Puerto Rico. I did it and cut the SIM card, the phone worked great for four days and now it doesn't. I just say No Service.

I try the sim in another unlocked iPhone and it works and also try a Claro Mobile sim in this one and it also works.

what can be happening? What can I do to make the phone work?

i will appreciated your help. I been without a phone for more than a week.

thank you!
