Im a Tamil Nadu BSNL customer.

Im in Student Power plan. I bought this number only to send group sms for free. But when sending sms in group, i receive a message like "Charge for last sms is 0.00 and ur balance is ....." after every sms. If i send a sms to a group of 20 members, i get 20 such sms which is really annoying. I cant send sms admist these sms. After call also, i receive such sms. This is not delivery message. Its some service message.
