I have vodafone sim card I thought that vodafone has best range but it is not good in our area but has very fast network connection in other areas. I live in awhalwadi anf there is bad network service.
My phone no.8390937036 has very slow internet speed and sometimes it don’t have network for calling also.I called vodafone care but they don’t give support to me they block my phone no. and then I didn’t call the vodafone care. I was very unsatisfied with this card but now sim card gives superb network.
