If you are planning to buy new Reliance Jio connection, then having only 4G supported phone is not enough. In order to make & receive calls, your phone must have VoLTE functionality.
What is VoLTE technology?
I have already explained it here in brief, but still I’m gonna highlight some main points here.
VoLTE means Voice Over Long Term Evolution.
To make it simple, we will take an example of Whatsapp. If I want to make a call through whatsapp, I must have an active mobile data connection. Not just that, but my friend who is gonna receive my call should also have internet along with whatsapp.
Same is the case with VoLTE calling.
If your phone has got VoLTE support then you can call to anyone BUT the condition is, receiver’s phone must have VoLTE enabled to receive your call. Even if he has got 4G phone but no VoLTE support, he will not be able to receive calls.
Since Reliance Jio supports only voice calling over VoLTE, your phone + receiver’s phone must have support for it.
How to check if my phone is VoLTE enabled?
1] Open your dialer & enter this code : *#*#4636#*#* (not working for few samsung phones)
2] Now you will see various options like wifi information, usage statistics etc. Just tap on ‘phone information’ button.
3] Scroll down….can you see ‘Turn off VoLTE Provisioned Flag’ option? If yes, the congrats! Your phone supports VoLTE!!
Note : Do not click on that option. Just press back button & enjoy unlimited free calls. 🙂
I have seen many people here who are getting problems while making calls & this is the only reason behind this.
Most of the phones which are running on Lollipop are now supporting LTE but if you haven’t got this feature then here’s a little fix for you. 🙂
Download JioJoin app & use the in-built dialer for making calls. This is the only way to do until you receive software update from the manufacturer.
