If you are buying windows phone plz read this. I have lumia 950 4G phone with VoLTE support but the reliance jio didn’t created any VoLTE sim application for windows phone. The phone is able to use LTE internet networ but unable to us VoLTE network. Thats why I unable to use VoLTE calling and SMS. I can only able to use internet only. While I try to make call using jio the call is automatically drops. So if YOU ARE WINDOWS PHONE USER YOU WILL GET JIO ONLY FOR INTERNET NOT FOR CALLING AND SMS.
