Unlocking The Modem with The Unlock Code
To make use of the unlock code, insert an unauthorized sim card to your Huawei modem. Unauthorized sim card meaning sim card from any operators other than the one the modem is currently locked to.
When you do so, you would be prompt for the modem’s unlock code. Just enter the unlock code you have generated earlier and, you can now use your Huawei USB modem with sim cards from any other operator.
I have tested it on my Huawei E1550 and it worked perfectly.
