Can I use Jio SIM in iPhone 5s?

You can use a Jio SIM in an iPhone 5S, but there are some limitations and requirements to be aware of:

Data Usage

The Jio SIM will work for data services on the iPhone 5S, and you will be able to use the internet without any issues12.

Voice Calls

However, making voice calls directly using the Jio SIM on an iPhone 5S is not possible due to the lack of native support for VoLTE (Voice over LTE) on this older model. To make voice calls, you need to use the Jio 4G Voice app, which is a separate application that enables voice calling over the data network25.

To enable voice calls, you must:

• Install the Jio 4G Voice app from the App Store.
• Configure the app according to the instructions provided.
• Ensure that your mobile data is always on, as the app relies on data connectivity to make and receive calls25.

In summary, while you can use a Jio SIM for data services on an iPhone 5S, you need the Jio 4G Voice app to make and receive voice calls.
