It was pretty easy. Waited a little longer than I wanted to but that’s ok. I am still very pleased with the service especially being from a small country. Keep up the good work !
Satisfied Customer. I am not too hot on technology and I booked my appointment at an inconvenient time for the technician. But he dealt with me efficiently and patiently which I really appreciate. Go...

Frequently Asked Questions
What do I need to unlock my BlackBerry device?
You need your BlackBerry device at hand and be able to access the keypad and dropdown menus. You will also need an e-mail address where we can send you simple instructions to unlock your phone.
I don’t know the model of my BlackBerry. What do I do?
If you do not know the exact model of your BlackBerry, or equivalent model, click here to find out using our free make and model search function.
I don’t know to which network provider my phone is locked.
Don't worry, we don't need this information to unlock your BlackBerry. Just select a network provider from any country and fill out the rest of the information correctly, because the unlocking instructions you'll receive by e-mail are the same for all.
Of course, if you are in the market to buy a used phone or need to know the network to which your BlackBerry is locked for another reason, find out instantly with our original operator check.
Does my BlackBerry have a limited number of unlocking attempts?
Yes. Check the number of unlocking attempts remaining prior to requesting an unlocking code. Please note that if you have run out of unlocking attempts, we will not be able to unlock your phone. This is why it is very important that you request an unlocking code through a reputable phone unlocking provider offering you full guarantees. Avoid cheap and untrustworthy online providers because they could easily damage your BlackBerry. Your BlackBerry will display the number of unlocking attempts remaining when you insert a SIM card from a different network provider to the one the phone is locked to.
What happens if I have exhausted all of my unlocking attempts?
At the present time, we are unable to unlock your BlackBerry if you have exhausted all your unlocking attempts. We highly recommend checking how many you have left before requesting your unlocking code.
Is the unlocking permanent?
Yes. Unlocking your phone with doctorSIM is permanent. You can also restore your phone to factory settings and download all official software updates without fear of your BlackBerry locking again.
What happens if my BlackBerry’s IMEI has been reported or blacklisted?
Reports are additional security measures which prevent the phone being used normally and are not removed by unlocking the phone. You can still unlock your BlackBerry, however you will not have full use of the phone until it has been removed from the blacklist.
