I was use Vodafone sim card but I am not satisfied with of this service.with my expiriance Vodafone is very bad network. It has very costly service plans. No any unlimited plans in this service the customer care service also very bad I used this service 2 months. So I feel very uncomortable. The internet service of this operator is very bad only 5-6 kbps spead. And the charges is very high. The network coverage is too bad the network always remains no service or emergency. I think no other network bad as Vodafone. Thanks
