Need advice on unlocking from Movistar to Tmobile? We have a customer in our store who has an iPhone 4 locked to the GSM network "Movistar" which is a spanish carrier.
He wants to unlock the phone to use in the United States on T-Mobile's network.
What would be the best route to unlock the phone? Gevey sim? Something else?
Our shop does not specialize in unlocking so any advice would be great. We would love to add unlocking to our list of services.
Thanks! |
