Samsung — Some problem in netwrok.

Address:

New Delhi, Delhi

I have earlier submitted the problem. After observation, I am again submitting the problem of MTNL sim in Samsung Galaxy Duos GT 7582. Most frequently, a message while dialing used to receive not registered on network. After restarting, problem gets resolved. Some times the problem was also notices with Vidafone post paid sim. People used to call on both sim, last Sunday, no call has been received. I have also put the sim on general mobile set but such problem was not observed. Please do the needful as this set was purchased in June, 2014. I reported thrice to your service centre but problem has not been solved.
