I have used the aircel services but I wasn’t able to use it more than 2 months as it was just simply frustrating and me continously hunting for the signal even for 2g.The main problem you can say is that network is never fast even in signal.
I recharged for 3g network and all I see when I open YouTube is just buffer and buffer. That is on 3g network. In 2g network I cannot even use what app the signal is always poor to even send messages.
The call quality is always noisy and the other person have always trouble of hearing what I am saying and always weird noises. The connection drops automatically when taking and I sometimes I needed to dial 10 times to make a call as the call will keep o dropping.
The other frustrating thing was it will lose signal and there will be reception at all sometimes and I have missed many important calls because of that. The H+ signal is always disappearing and I cannot just use Internet peacefully and the reason why I stopped using their services. Not a very reliable network.
