This is an very good network I am useing vodafone sim since 5 years it never made me any trouble about its network before I use bsnl sim and I have made poteble to vodafone still vodafone dont have 3g and 4g in our area but its 2g is very good in 2g also its net is very speed and if vodafone launch 3g or 4g in our then it will beat all the network because its 2g is very speed then why cant 3g or 4g if vodafone 3g or 4g comes all over india then it may beat all the networks with high speed internet and its servies is also very nice , I love vodafone its very good its charges are also good not more.
