Hi,

I am with Fido (service provider) in Montreal, Canada and have a hard time sending text messages to other Fido users in the same Area Code.

I called Fido and they gave me the number for the SMS Center and told me I have to find out where to enter it myself.

I don't know where to enter it, and i searched a lot of forums but still no closer.

Please Help

im pretty sure its stored on your sim card
try setting it on some other phone and insert the card back into iphone
hope it helps
