Im tying to unlock an Iphone 4.

the celular company make it by its system, and send me an E mail with the instructions to finsh the process by myself, throug itunes.

I did every step, and at the end appers a message telling that my Iphone is unlocked.

but it does not work with other celular company sim card.

It only works with the original sim Card company.


In the Iphone appears a message teeling that has no service with another company's sim CArd.


I don't know what to do.

I've been doing this, with different Sim cards.


sometimes appears a message informing that the SIM card is locked with a PIN. That i must instal the last itunes version and connect it again.


but every Sim card I have are with PIN.


If you can help me I;ll be very glad.


Thank you very Much.



iPhone 4, iOS 6.1.3
