I got more comical replies from BSNL customer care.I tried each and every USSD command from *123#, *123*1#........9#, *124# and everything. Nothing shows the remaining data that can be used. After disconnecting a connection, im getting sms frm BSNL like YOU HAVE USED NET FOR XX MINUTES & CHARGED Rs.XX. Balance remains same. But im unable to know the remaining data.Called BSNL customer care and tried and tried and got the line after 30 min. CC person said me to send sms DATA 3G to 53733. I tried tht but it said "Dear Subscriber Pl dial *123# to check the details -BSNLMOBILE"Again i tried CC. Another CC person said to send sms 3G DATA to 53733. After sending, i got a sms "Your Request for 3G Information Recieved.You will be contacted by our customer care soon - BSNLMOBILE"I didnt give up. Again i tried CC and got the most comical answer frm a CC person. He said me to go to nearby BSNL office and check the remaining data that can be used.Dunno how to use this crap without knowing the balance usage.
