How do I change the sim card over from Optus to Telstra, do I have to restore the phone settings before I remove the old sim and again after putting in the new one?
iPhone 4S
First, ask Optus to unlock the iPhone. Then change the micro sim.
Thanks ckuan, however that's only part of it.
Get Optus to unlock phone
Go to itunes click on Restore
Back up and Restore
Turn phone off
Remove Optus sim card
Pop in Telstra sim card
Turn on phone
Go to itunes again
Set up phone settings &
Restore from previous back-up
All done yay
Glad to got it sorted.
how do I change from an optus sim to a telstra sim, do I have to restore the phone?
