MTS (MTC) of Russia has launched two variant models of Huawei E5372 4G WiFi MiFi router, called it MTS 823F and MTS 826FT. You can find E5372 locked to Beeline of Russia and Altel of Kazakhstan also. These all devices can be unlocked with unlock code, as I have already mentioned in the unlocking of Huawei MR100-3 Megafon.
