I am using vodafone prepaid sim.
I am very satisfied of this company.
Vodafone network is very good.
Internet speed is superb in 3g or 2G browsing.
But vodafone plan are too much highly expensive.
Ther plan rate are more expensive then other operator.
There network service is fully excellent.
Vodafone network is best network.
If u have any problem faced to this service then u can contact the customer care and they are discuss with u for your problem.and try to solve the problem in short time.
Overall Customer call centre service is good.
