I have been using Vodafone network past 6 years and till yet I havent got any problem. Only once I got a problem was when I hadn’t reverified my Mobile number using aadhar card my phone was down for 3-4 hours. Then automatically the network recovered with a sms from the company for reverification of number as fast as possible. Else past 6 years everything is fine. I never had network problem. And company also dont send unnecessary messages. The service of comapny is very good. But a little negative point here of the company is its slighty costly than the others. But the company provides the service completely and satisfy all our needs and the coustomer service s of the company are as well good. They are fully co-operative and help us recover aur talktime if we lose it accidentally by our own by activating any tariff plan or vas services. At the end I suggest you to use Vodafone network due to its heart winning services and high speed internet network. Thank you.
