I recently bought the Huawei E3531s data card to use in my hostel. I had initially planned to use it with a BSNL SIM but I realized that the BSNL 3G around this area is slower than 2G(Sector 12, Chandigarh). I have a Reliance Mobile 3G SIM that I would like to use in this Dongle. However from what I know, if Reliance detect that I am using this SIM in a Dongle rather than a Mobile Phone, they may annul my 3G balance. Is there any way I can escape that? I am currently using this SIM in the dongle using the APN that was there in my mobile phone and it seems to be working fine. Are there any more precautions I need to take?
