This is one of the top cheater networks among others. That only knows, how to take money from customers by offers top prepaid attractive plans. I live in New Delhi near Punjabi Bagh -India. where it has very few towers for the network like one or two rarely. which does not give me true network experience, thats why I port my mobile no to Airtel for good service. As this is the only network that I had from my 1 mobile device.
Vodafone gives you network for data when you are not active on data packs but when you are purchased the data packs, you will cry for your decision. so it suggests you move out from Vodafone as why dont you choose Indian network operator rather than British network operator.
But they have good service crew on offline bases at the store, not on the phone call with the service center, as the crew at the Punjabi Bagh are more helpful, polite and know how to deal with customers more than Airtel at the same area.
