Recently, I have provided the download link of Nokia PC Suite V 7.1 and Zune PC app for Nokia Lumia and Samsung Kies latest version for Samsung Mobile (Windows & MAC OS). I have also shared Telstra Australian broadband software and firmware download links. I generally write an article about unlocking as you can find the unlocking solution of Huawei E5373T Telstra Australian WiFi MiFi router. Today, I have come with the unlocking solution of Huawei E3531 modem. In this article, we are not talking about only the unlocking procedure of Huawei E3531 dongle, but I will also provide the firmware download link of Huawei E3531 for both hilink and normal modems. Don’t update the normal modem with hilink modem firmware and vice-versa, otherwise, your modem may be dead.
