I have one Huawei EC325 CDMA data modem. Earlier I used it with a prepaid no. and after that I stopped using it because of speed. Now after 6 months I am again trying to use it with a new prepaid GSk but the data modem is not accepting the new GSK. I complaint this matter to reliance webworld and other senior officials but all are not able to help me. Can you help me in this case or should I throw the data card ?
