In a previously written article, I discussed some reasons why I prefer to use a previously unlocked dongle to using a universal one. In this article, I will write about how to go about unlocking modems that have been locked to the particular network they are branded to. Several companies manufacture modems. The popular of these companies or rather the companies whose modems are common in Nigeria are Huawei and ZTE. In this article, I will discuss how to unlock modems manufactured by Huawei.
Each modem or dongle has a 15-digit number referred to as its IMEI number. For Huawei modems, the IMEI number is used to calculate the unlock code. What do I mean by the unlock code? If you’ve ever tried using a modem belonging to a particular network with an alien SIM card (I mean a SIM card belonging to a different network), once you insert the modem into your computer, a small dialog box comes up demanding for the unlock code. The unlock code is tied to the IMEI number. In other words the IMEI number is used to calculate the unlock code as I mentioned earlier. You can get the IMEI number from the modem pack or on the body of the modem. If you do not see it there, don’t panic. Simply insert the modem into your computer then open up the modem interface. On the interface, click on the “Tools” tab and select “Diagnostics”. You should be able to get the IMEI number from there.
There are softwares that calculate the unlock code of the modem from the IMEI number. The one which I use regularly is called HUAWEI UNLOCKER. I’ll give a link to download it towards the end of this article. The software only demands that you input the 15-digit IMEI number into it and it automatically calculates the unlock code together with the flash code. Copy out the unlock code. DO NOT copy the flash code. The next thing you do is to insert an alien SIM card into the modem, then plug the modem into a USB port on your computer. Wait a moment. The dialog box requesting for the unlock code should come up. Enter the unlock code into the text box provided and voila, your modem becomes unlocked. You have ten (10) attempts to input the correct unlock code. If the dialog box doesn’t come up, two things could cause that. Either the modem has already been unlocked or that the number of times that has been given for the correct unlock code to be entered has been exhausted in which case it can no longer be unlocked.
After reading this article, I don’t think you should have any problems unlocking your Huawei USB modems. If you encounter any problems, just use the comment box below and I’ll respond as soon as possible.
