2 years ago I brought you (1 2) the worlds first huawei modem unlocking guide which attracted more than 5 million people and over 5000 comments. But things have changed now, there are different modem models, and the way of calculating the codes for those are different and you cant use my old method to unlock these new modems.
You can register a account there and politely ask for the code on the forum. Dont forget to include your exact model and IMEI number. Usually in few hours someone will post the code for you. After you receive the Unlock/NCK code its easy to unlock the modem.
