First of all I would like to tell you my opinion is
limited only to Airtel Andhra Pradesh.
Well, As far as I have seen in Hyderabad, Airtel is the best
and I would not recommend anything else. I have had a very
bad time using other services like people asking me..
Are you really using a mobile or something else??
I do not know whether this is an appraisal to Airtel or depraisal
to others, but I cant just forget what I suffered until I
switched to Airtel. No one has ever complained me that I could
not get connected or something else as it used to happen.
Even though the charges and financial schemes etc are all
the same among all the service providers, the first and foremost
thing is the connectivity. I am satisfied with the service.
I get connected wherever I go within AP and also a good connectivity
service throughout south India.
Well, all the does not mean that there is no minus.. it is, but
very very less.. like it happens during the evening time if
the network is tooooo busy that you do not get connected.. but
when you see the rest, you can just ignore that.
Hats off!
