Huawei corporation had launched various CDMA modems in the past. One of them is the Huawei EC321 Data Card. Today, I am writing for Huawei EC 321 modem, or you can say wingle unlocking. Before proceeding with the unlocking process, let me very clear, this model is too old, and I have not checked personally. I am writing the unlocking of EC321 on my own experience since I have got success in various old CDMA modems. You can find the unlocking solutions of EC156, EC1261, EC306, EC122, EC226, EC150, etc.

As you can see in there is nothing hard and fast in the Huawei EC321 modem, which is required for unlocking. After unlock, you are nothing going to get in this modem. Still, if you want to gain some experience and have a Huawei EC321 dongle at home, and that is not used, you must try. One word that should be remembered in the whole like that makes life easier is “Something is better than nothing.”
The unlocking process of Huawei EC321 Wingle is the same as I had earlier mentioned in Huawei EC315 Wingle. Only the difference is the firmware. You can get the firmware update of the EC321 Huawei modem from the download link mentioned below.
