warning: blocked iphone will block sim card as well!
 

customer brought over an iphone 4s which is factory unlocked-he was getting message "this device blocked" so i put in my sim card and it blocked that too!-put my sim back in my phone and it is blocked! this is a first for me-i knew they could block devices but not sims-customer ran away before we could try a tmobile which i am sure would not have be blocked right? of course a new sim fixed my problem but just watch out for this phenomenon.

which network is it from?

At&t ................

I'm worried about your customer ... he can be blocked by ATT also, please check him ASAP
