This service can generate the unlock code of Alcatel phone/tablet. To generate the unlock code we need IMEI and PID. To get the Provider ID (special sequence of numbers and letters), remove the battery and check the sticker. Or, it can be also found in the phone settings. Eg. 4015Y-2AGKBC.
You can get the IMEI of the phone through its Settings or by dialing *#06#.
