Using IMEIDoctor, we can unlock your iPhone 4 in a matter of hours to be able to use any sim card worldwide.
When you purchase an iPhone 4, you are restricted with using only a sim card from the original carrier. 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 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 iPhone 4 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.
