I used VI Sim 2 year ago but due to bad network I got my Sim ported to Jio sim.VI network is very weak in our area thats why the network is ever live in our phone. so never. This even costs( 1.5GB/month 249) more than other( jio or Airtel) companies so we move to other network.Its recharge plan is more than Jio and Airtel and network speed is low.so Improve network.
