Aircel is the one of the leading mobile operator in india .i have use this network since nine months without any problem.this network has 3g internet.this network has weak signal in some villages and highway and then strong signal is the towns and cities.this network has developed recently because it can be available in low price and strong signal in towns and cities.and the disadvantage of the networkweak signal is villages and highways.I suggest to buy of a aircel network without any problem in towns and cities.
