It is very simple to unlock Alcatel modems. Just put another SIM card to modem, then modem will ask you an unlock code like RCK, NCK, NSCK or SPCK codes. By entering that unlock code, your modem is free from all locks. Then you can surf internet without any blocks.
Some modem will ask two unlock codes like RCK and NCK codes to unlock.
Example: Unlock Alcatel STC X230l modem:
Ø Connect modem and install built-in software and drivers. See image before unlock (‘Surf’ button disabled).
Ø Now again asks NCK code to enter, NCK code entered.
