I am using aircel sim last 2 years and I can say aircel network is too bad and if network is not good than how could we imagine that it will give you high speed internet lots of my friend shift their network from aricel to others networks and I am also going to shift or port this network I am not doing right now because I am using aircel from 2 years so all my freiends and relatives know me by this no otherwise I will not take 1 sec to change this network.
