Now a days I am using 3g aircel sim. This is the worst service I have ever seen. Whenever the power goes off their 3g service is turned off. 3g service is not available when the electricity is gone, it will only come when the power comes back.
As in most the mobile operator data transfer scheme is available, aircel wont supply this scheme.We cant transfer the data.
They give many offers on but they never said it is limited to every user. Every scheme is limited to number of times in aircel. For example offer 45 is available up to 22 times per user.
They only sell 3g sim but never provide 3g network.
