Most service providers sell customized huawei modems which they’ve already programmed to work only on their network. You might get a prompt to enter an unlock code if you try to use a sim from another service provider on these USB modems. There are several ways to unlock these huawei modems though.
Some kind person in a web forum might create a topic on this, asking people to drop ther modem’s IMEI number but the best way to do it is DOING IT YOURSELF!

There’s a modem unlock tool in our mobile site
It’s a very effective tool which I’ve used on several occasions and it’s never failed once. All you need to do is to key in your IMEI number and hit “Enter”
You get your unlock code starught up!
Click here to check out this tool.
You can as well unlock it wit Universal Mastercode. This also works for Nokia, LG and some other products apart from Huawei USB modems.
Download Universal Mastercode from Mediafire or Rapidshare.
1. Select Huawei from the tabs
2. Enter your IMEI in the provided space and click calculate
3. Insert an unauthorized sim in your modem and plug it in
4. Enter the unlock code when the prompt message comes up
5. You’re done!
