[Resolved]  Samsung J700 Mobile — hanging phone with perticular mobile number

The mobile is hanging if SMS comes or missed call comes,
Earlier I was using airtel postpaid now I changed to prepaid with same number.after changing in to prepaid, The problem is happening with perticular mobile number SIM (99xxxxxxxx) in perticular mobile(samsung J-700 handset).after changing to prepaid also I changed the SIM one more time.

The SIM changed and checked (in other SAMSUNG mobiles) no problem with SIM working in other handsets of samsung.

Please solve this problem If I goto AIRTEL they are telling problem with handset If I go to Samsung service provider they are telling problem with SIM. Since I have the same number from past five years i am not interested in changing the mobile number.
