I was trying to buy a daily pack and found this 6rs GPRS pack which is valid for 30days and charge for 100kb is only 2p(20P/MB).
I think it is available in most of the circles….
dial *141*4*2*1*1# to activate….
This plan is very suitable for people who use less data but use it frequently. specially for people like me who go use mobile internet when out of home and need to check map etc…
the main advantage of this pack is that, it is valid for 30 days.
