Vodafone is a very big multinational telecom company. I am here to review the vodafone in india. Vodafone has alot of users just because of its network service. The network is very good if you compare it with the other telecom companies.
I used the sim of vodafone about 1 year and faced alot of problems so I decided to port my number to docomo. Now I am very happy with the performance and charges.
The tarrif rate of vodafone is very high and not have any tarrif which can reduce your call rate to negligible. The SMS packs of this mobile operator is very high. They don't give any warning message at the end of your tarrif which causes a great problem. They automatically add value added services on your mobile number and deduct your mobile balance.
The important things is the data pack rate is very high of this operator and don't gives a very good internet speed. The 3G pack is just named of 3G pack and sometimes gives speed poor than the 2G.
overall while concluding I suggest you to don't buy the simcard of this mobile operator in the case you want low call rates.
