After updating firmware to 14/4/14 the incompatibility remains. TP-Link support is sleeping !!! Even tried updating firmware on another new MR3020. No support for MF825A.

TP-Link support, please update firmware at the earliest. Tried everything except openwrt. We can then start selling TP-Link 3G routers here since the Airtel 4G routers (with SIM slot) has 4G range...

Sept 2013 firmware also does not support ZTE MF825A. Wonder when it will be supported in the firmware ! MR3020 otherwise working with DoCoMo 3G perfectly.
