Will Huawei Mobile broadband dongle E303C support 4G sim?

Question

When Airtel SIM with 3G data package is used in Huawei E303C and plugged into the USB port of HP Sleek book, I am not getting the Internet connection properly. I get ERROR 522 Ray ID 28947a;2837a. Kindly advise how to solve the problem.

Answer 1

After some searching I have found that this device is 3G ONLY. This means you can attach a SIM card, but the maximum connection speed you'll get in a full supported section will be 3G. For 4G another device that has support for 4G networks is required. You will have to visit a local modem seller to buy one that has 4G capability. There is no tweak or firmware update to make this device compatible with 4G networks.
