When airtel 4g is launched I wass the first to purchase the sim for it
and also when the demo guys ame to give demoo of the speed
the speed was excellent and I really appreciated it
as the times goes on sometime 4g is equal to the 2g
it gives 20 kbps persecond
while 3g speed is also more thn 3 mbps of other network providers
I am very disaappointed with it
and when I deactivated my sim they charged me additional 400 rs for deactivating it
totally the useless company
