Vodafone is one the trusted networks. Its been several years since I hv been using Vodafone network. Although it is a bit expensive but the quality of network and service can be trusted upon. the internet speed is also very high and there is seldom any disturbance in calling network. They also have many plans which are very economical. They also have several offers on roaming and international calling. we can easily navigate between cities with Vodafone. this is a very genuine company and gives sufficient amount of time to the users to pay the bill.
