Jio sims are in cheap to use calls and DataRecently, Reliance Jio sims takes in the first place of communication networks. Most of the people who have 4G mobile phones, they prefer to take Jio sim for free of cost to calls and data. I don't know for what purpose these sims are being sold. But, customers are enjoying the service of Jio sims.
At the initial stage of selling these sims, there is a rumour that this network would take the mobile code to prevent another sim to put in the slot in the phone and regular rental charges are asked to pay after completing the free period.
