4 Best Methods to Unlock iPhone 11/12

Following are three methods to unlock iPhone 11/12

Method 1: Contact your carrier for unlock code

When a customer signs a contract with a big cell phone company for a certain amount of time, they often get a discount on a device. Because of this, the device comes with a controller lock so customers can only use it on their network.

You can leave without paying anything if your agreement with the company is over. You must meet the following requirements before you can unlock your iPhone:

  • First, the device must be legal. It means the device has not been reported as lost, stolen, or connected to a crime.
  • Then you shouldn't have any debts in your bank account.
  • If you signed a contract in exchange for a lower price upfront, you would have to wait until your contract ended (usually 24 months) or pay the remaining balance if you bought your phone on a payment plan.

Note: the unlocking process is different for each company.
