I had earlier shared an unlocking solution of EC306 with only the CDMA workshop tool, but that works on only Tata Photon Max WiFi dongle. Now, we have come with a working solution for the EC306 MTS wingle too. MTS EC306 Huawei wingle has customized firmware and can be setting gets reverted. This means after unlocking again, and it gets locked to the MTS network. So, here we need to change the firmware for the permanent unlocking solution.
