Go and google for Huawei modem unlock generator, install it in your Windows and key in he IMEI. You will see a NCK code, copy down the NCK code.
Now use Hyperterminal, Putty or minicom to AT to your Huawei USB modem and issue the following AT commands.
AT^U2DIAG=276 <—- RESET TO FACTORY SETTINGS
OK
AT^CARDLOCK=55341785 <—– ENTER THE 8 DIGIT NCK CODE HERE
+CME ERROR: 3
OK
AT^CARDLOCK?
^CARDLOCK: 2,10,0 <—- IF STATUS IN THE FIRST NUMBER IS “1”, THAT’S MEAN THE USB MODEM IS STILL LOCKED. TRY THE ABOVE STEPS AGAIN.
Finally can use my Singtel, M1 and Starhub USB modem with Malaysia and Thailand 3G SIM card 🙂
