Frequently Asked Questions
How can I find out the original carrier of my phone?
The original carrier
is the network provider that sold the phone
(to you or the original owner) and is responsible for the fact that the phone is configured to work properly only with one of its SIM cards.
The phone will almost certainly only work with that specific carrier until it is network unlocked.
If you do not know your phone's original carrier, we recommend running
an Original Carrier Check
before submitting an unlock request.
How can I check if my iPhone is already unlocked?
You can find out if your iPhone is already unlocked by using doctorSIM's Locked/Unlocked Status Check. We highly recommend this check before submitting an unlocking request in order to avoid unnecessary expense.
This service is especially useful if you are going to buy a second-hand iPhone as you can obtain this information with just the device's IMEI number.
It would also be a good idea to verify if the iPhone is iCloud locked with our iCloud Activation Status Check.
I want to check if a phone has been blacklisted due to loss, theft, or unpaid bills.
A blacklist report is an additional security measure imposed by the original operator preventing the phone from being used properly.
When a cell phone is blacklisted due to loss, theft, or because the owner has pending bills, it will almost certainly not work on any network in the country of origin.
The only way to remove a phone from the blacklist is by contacting the network that reported it in the first place. doctorSIM cannot provide this service and does not issue refunds if the phone is successfully network unlocked but does not work properly on the chosen network.
Find out if your phone is currently blacklisted with our Blacklist Check
