No doubt that vodafone 2G internet network is the best network compare to other network. I completely agree with that provide highest speed of 2g. My mobile have both 2g and 3g network support of internet. When I required for recharge 2G internet anytime.
I always go rs 48 . they offered 250 mb + 250 mb for 28 days in our state. So I used this 2G pack many times. Sometimes I had little bit problem in daytime with 2g internet. Its run little slow but after evening it ran high speed. Thank you.
