I have been using jio Sim from about 1 months, , jio Sim is purely 4G Sim so supports only 4g devices. I am using jio Sim in my Motorola E2 4g, , , the Jio Sim have wide range of network coverage.But in my town there is no 4G network availibiity there I cannot be able to use 4G Sim, , , I am studying in area where LTE network is available, it is very useful to me. Jio has given data usage perday limit that is 1gb 4g data above it it will give 128kbs which new year offer .It is also gives unlimited voice and messages upto march, thank you jio??
