Hello friends I buy a gio sim for my android mobile. Its a good provide internat service. Mukesh ambani is a owner of gio 4g. Network coverage is very best in city or village. Good network but some times call drop to another number and call not connect in 1 times calling. Connect with in 2 - 3 times. Internat speed is very good like real 4g but some times is a very poor and shlow. Customer service is not a good its a very bad service provide by gio team. Charge and billing plan is very high becouse some times gio network service is very poor. In 30 days gio give 15th day good service. Gio is a good for internat
