Well I am too a vodaphone phone mobile operator user and I am totaly satisfied with the services given by vodaphone company.
The coverage is almost on all the areas . And the network coverage in the all areas is also good .
If you want to stay on the 2g plans offered by vodaphone company then the 2 g according to that is superb. You will easily get about 30kbps to 50 kbps or sometimes even 80 kbps which is very good speed for a 2g service plan as compared to other mobile operators. The 3g speed give by them is also preety good.
You will get 2 mbps to 4 mbps easily in a crouded area . The speed will be even more in metro areas
.
I am using vodaphone in panjab and it works perfectly. Hardly I feel any issue of any network coverage as I use to visit different areas . So network coverage is very good.
There is no call dropage . I had been user of this for about one and half year and had hardly feel any call dropage problem .
Besides all this vodaphone is not too costly as compared with other mobile operator companies.
2 g net is very cheap and 3 g net is also very cheap. But from my personal point of view you should recharge and go with vodaphone 3g.
Vodaphone is also may probably goint to launch its 4 g net services .
You you should go with vodaphone. It is best
