A SIM lock is a technical restriction built into GSM and CDMA mobile phones by mobile phone manufacturers for use by service providers to restrict the use of these phones to specific countries and/or networks.
Own a network locked iPhone? We can help. Unlocking an iPhone does not require an Unlock code, or any type of sequence. It is officially unlocked on Apple servers, which means that even after updating the system or making a factory reset the device will stay unlocked.
In order to unlock an iPhone you need to provide the IMEI number, which can be found by dialing *#06#, or by checking in the iPhone settings.
Second thing is to provide the correct network for unlocking.
You always remove the blockade from the network in which the iPhone was bought, not the one that you will be using in the future.
If you don’t know the network you can use iPhone network finder.
The last thing is to check if the IMEI number has been reported as stolen, lost, damaged or the bills where not paid for the contract.
