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.
But its still possible to unlock new Huawei Modems such as
- Huawei E353
- Huawei E173cs-1
- Huawei E367
- Huawei E353 Wu-1
- Huawei E353 Ws-2
- Huawei E303
Calculating unlock code is little bit of mystery at the moment. However you can obtain the unlock codes from gsmhosting.com forum for free. See the thread here http://forum.gsmhosting.com/vbb/f88/free-huawei-e353-e367-unlcok-codes-1507232/
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.
Download and install the Code Writer from here http://www.ruchirablog.com/go/code-writer and process is quite simple after that.
Click the Detect button and Accept your comport. Then it will ask for the unlock code, enter the you got here
Click OK button and voila its done 
For old huawei modems, read my previous guide here http://www.ruchirablog.com/unlocking-huawei-hspa-modem-for-free/
