I Ported my number from Aritel to BSNLand the new BSNL SIM is not supporting call conferenceand while i'm using gprs, a new call comes, the gprs goes to "HOLD" mode. ( My old Airtel sim had call conference and can accept calls and provide gprs facility at the same time)is this because of poor capacity of my bsnl SIM? ( airtel had 32k sim)Buying a new USIM will solve the problem?CAN ANYBODY HELP ME ? PLS :iomg:
