I Use Reliance Gsm Sim in Panipat Haryana ( India). When I am using internet on my mobile redmi 1s then Reliance internet Speed Is very slow. Its speed is up to 60kb/ps on 3G Network. Its call rate was very high and network coverage was not good. When I am calling to any mobile then call was not connecting due to Network Error.
So I can port my sim to another mobile network operator for a better experience because of network issue.
