Before one 1 year I was using reliance gsm and when I recharge my no more than 50rs they automatically activate any service in my no and when I call to customer care then they say your are activated this service by dialing some no and some time they activate caller tune and some time and other service that has no use actually so I was irritated and decided to port my no and now I am using Bsnl network was also weak voice also not audible clearly on that time call drop was common for reliance operator.
