Hello all, I am using reliance netconnect + . I purchased it in chennai I shifted to pune a month back in was using it in a normal way. The speed was awesome. Last 3 days my signal is totally dead. I am staying in hinjewadi, Pune I could not find a single store here or a company rep to talk to also. When I call customer care I was told network is getting upgraded.. what should I do now. Can someone help me out to shift to reliance 4g and etc... Name: sanjay.d Mobile no: 9840858209
