I Recently Had My Reliance Data Modem Service Terminated... 
Because It Was Not Worth The Amount I Was Paying 
Speed Was Dead Slow... 
I See That There Is A Slot To Insert A SIM Card (Or Whatever, Just That There Is A Slot To Insert A Card) So I Was Wondering If I Can Use This Data Modem (HUAWEI EC325) With Some Other Service Like Airtel Or BSNL Or Any Other...
