How to open my phone locked network

Contact the wireless provider to which the iPhone is

locked to see if they offer unlocking and if you qualify.

Only the wireless provider to which an iPhone is locked

can unlock it.

What does it say when you look at Settings>General>About>Carrier?

You may have to scroll to see the entry for Carrier.

To check if iPhone is locked to a Carrier, put the sim

you intend to use into the iPhone. If you get no error

message, the iPhone is not locked to a wireless provider.
