Two years ago the call drop problem and 'No signal' problem was prominent in Nerul, Seawoods, Belapur and Kharghar from where I make most of the calls. After repeated requests the issue was addressed substantially, but it has crept up since past two months.
About billing no issues.
How the company will perform when many will have 4G services soon ?
