Very good to use Jio sim in my Samsung Note 5 phone. I don’t have volte in my note five but Jio make it easy to call with their Jio4GVoice software same like volte experience. Downloading speed is very good in our country India like European countries. I have 10.39 MB downloading speed per second which I checked with TRAI my speed app. I can say Jio is the future of India bcz India is getting digital. I like its free plan for customers with good net speed n rich calling.
