Huawei corporation had launched various CDMA modems in the past. One of them is Huawei EC321 Data Card. Today, I am writing for Huawei EC 321 modem or you can say wingle unlocking. Before, proceeding with 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 the success in various old CDMA modems. You can find the unlocking solutions of EC156, EC1261, EC306, EC122, EC226, EC150 etc.
