Huawei is a well know data card manufacture. It is so popular because it is easily unlockable and readily available in the local market. Recently, the manufacture has launched Huawei E3121 3G 14.4 Mbps Data Card globally over the world. MTC in Russia has launched E3121 as 320S, 320D. We have already shared the universal firmware of the Huawei E3121 dongle as well as unlocking solutions also. This article will share E3121 data-card features, specifications, and my reviews of the Huawei E3121 3G device.
The E3121 is a nice device to surf the internet with blazing fast speed. Its maximum download speed is 14.4 Mbps as well as it can upload any file with the highest speed of 5.76 Mbps. Since E3121 is not a WiFi dongle like Huawei E355, it can still share the internet up to a maximum of 5 devices by making your laptop a hotspot with Huawei Soft Wi-Fi feature; this is the beauty of Huawei. Sharing & surfing will seem like fun and enjoyment with all new E3121 Datacards from Huawei.
