I had using vodafone sim card for last 10 years. My family members also using the vodafone sim card. Nearly 12 sim cards are used by me and my family members. But the cost is more when compare to other network. I also accepted that no other network is as fast as vodafone. The vodafone 3g speed is approximately 800 kp per second. But the only thing is cost. There is no new data plan for 3g. The talktime for 1 minute is 1.20 rupee with out using rate cutter. The chotta credit facility for 10 rupees is very nice.
