Using IMEIDoctor, we can unlock your iPhone 4 locked to ATT in matter of hours to be able to use any sim card worldwide.
When you purchase an iPhone 4 locked to ATT, you are restricted with using only a ATT sim card. This means that you cannot source cheaper deals elsewhere, and you have to use expensive roaming fees when travelling.
With our safe, legal, and official Apple sanctioned ATT iPhone 4 unlocks, you can free your iPhone 4 from the restrictions of a particular network. Our quick and easy process is performed "over the air" via Wifi or cellular connection by whitelisting your iPhone 4's IMEI in Apple's database. You can continue to use your iPhone throughout the process, which takes around 12-24 hours.
All of our ATT unlocks are covered by our no quibble, money back guarantee, giving you peace of mind with the process.
Your AppleCare warranty is not affected by unlocking with IMEIDoctor.
