Frequently Asked Questions
Can a locked iPhone be unlocked?
If your iPhone is network locked and it only works with the original carrier, yes, we can help you network unlock it and use it with any carrier, from any country.
doctorSIM's IMEI network unlock for iPhone service is a permanent and international unlock. You can update your iOS version and reset the phone, and it will remain unlocked.
Please bear in mind that our service does not remove the blacklist. If your device is blacklisted as lost, stolen, or with unpaid bills, you need to contact the original network carrier to remove this restriction, otherwise you will not be able to use the phone properly.
Not sure if your phone is blacklisted? You can run the IMEI check with our quick Blacklist check Blacklist service.
What is the Locked/Unlocked check?
This is a quick and efficient service that lets you check whether your iPhone is unlocked and can be used with any carrier, or if it needs to be unlocked. To unlock it, you need to know which carrier originally sold the device. If you don't have this information, we can help you with our Network Carrier Check.
Does doctorSIM remove the blacklist block?
Our services do not remove the blacklist block, as this is an additional restriction set by the device's original carrier when a phone has been reported lost, stolen, or with unpaid bills.
The blacklist block can be removed by the phone's legal owner, who must contact the network carrier and settle any pending issues or payments.
