Jio is a revolution in the telecommunication sevtor.when jio sim is not aviliable on the market then the recharge of internet is too high and expensive.every people cant affotd expensive jio
After the jio aarival in the market then all the data packs of every telcommunication services is too much reduced
Major problem of jio is speed . some places jio gives good speed and some places bad and other bad things is that jio is used only 4g mobiles.
So my opinion is that jio launches those types of sim which is used in every mobiles phone.
