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 an Alcatel phone?
To unlock your Alcatel, you need access to the internet and an e-mail address where we can send you simple instructions. You will also need to be able to access the keypad and dropdown menus of the phone.
Do I need to know the exact model of my Alcatel?
Yes, you need to know the exact model of your Alcatel prior to requesting an unlocking code. If you do not know the exact model, or equivalent model, click here to find out using our free make and model search function.
Can I still unlock my Alcatel if I don't know the original network provider?
Yes. 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.
How many attempts do I have to unlock my Alcatel?
You have nothing to worry about if you have never tried to unlock your Alcatel in the past. However, with some models you can see how many unlocking attempts you have left by inserting a SIM card from a network provider different to the one the phone is locked to. You will be prompted for the unlocking code and at the same time the phone will indicate how many unlocking attempts are remaining. If you have run out of unlocking attempts, it will not be possible 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 Alcatel. Your Alcatel 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.
Can I unlock my Alcatel if it has been reported or on the blacklist?
Reports are additional security measures which prevent the phone being used normally and are not removed by unlocking the phone. If your Alcatel has been reported stolen, lost or due to outstanding bills, you should contact the network provider to which the phone is locked to remove the blocking. You can still unlock your phone, you just won’t be able to use it until it has been removed from the blacklist.

Will my Alcatel lock again if I update the software or restore it to factory settings?
You have nothing to worry about. Whether you update the software or restore the phone to its factory settings, your Alcatel will never lock again. All our phone unlockings are 100% permanent.
Do you issue refunds if the unlocking code doesn’t work?
Yes we do. Although our unlocking codes never fail! However, if for any reason under the responsibility of doctorSIM your phone cannot be unlocked, we will issue you a full refund. Keep in mind that we do not issue refunds if your phone’s IMEI has been blocked by the network provider due to loss, theft or unpaid phone bill, or if it has no unlocking attempts remaining.
