How to use Jio 4G Voice App to make VoLTE Calls on iPhone 5s & 5C / iPhone 5 & 4

Reliance Jio has one of the best mobile data plans in the Indian Telecom market, but it has one drawback – Reliance Jio is a 4G only network and hence requires VoLTE enabled phones to make calls. Now, since all iPhones are single sim devices and considering iPhone 5S, iPhone 5C, iPhone 5 & 4S do not support VoLTE, Jio cannot be used as the primary network for receiving calls. But not anymore, In this article, we will cover how you can use your Jio 4G Sim to make & receive calls on any iPhone, even iPhone 5S using the Jio 4G Voice app.

How to Dial & Receive Jio 4G Calls on iPhone 5S, 5C (iPhone 5 & 4S) using Jio 4G Voice App –
