I have reliance jio dongle but so mach face the problem internet speed, even most of the time disconnected this for long time or not in connect with jio service. In the reliance jio we so many card in my family member but they always suffering connection problem whenever jio mobile come in range many time automatically fully disconnected all network range, so in case of urgent call or urgent necessary date we are unable to connect and found in jio network range. When call in customer care so many they are in busy in call unable to talk with customer care executive. In that way even so much provide poor & low service and also support to customer.
