I am a user of vodafone from past 8 years. Although earlier their was no problem. But nowdays their is a lot of network problem. The calls dont connect and when we complain they say that no towers are possible in the area. Though the charges are better than other networks but the internet services are very poor. Even after having 3g connection my internet works slower than 2g. Sometimes good offers are available but network is not good. Vodafone app is also their which gives certain offers like 1.5 times the internet pack. I would request the vodafone people to please improve their network  services and plant towers every where.  I am not satisfied with the connection just because of their network. 4g services are now started and one can upgrade it to enjoy.
