IMO Go with Airtel MO....
EDGE enable handset doesnt works if his local network wont provide EDGE,
I am using Gprs with 15-16 kBps d.w speed
... In just rs. 249 / month...
@Gigacore
Mate it only data transfer rate between pc and cell not the net speed....
when i connect my cell via bluetooth i get 115.2 kbps speed but with data cable its 460.8 kbps... its only data transfer rate...
It dont make much difference in net speed....
BEST bet would be AIRTEL MO
