Good ' Everything is unlimited, calls, data 4g, and sms.
Net speed is good but sometimes it is not good.net speed keeps up and down. It is not good .sometime I feel like breaking my phone.
I saw , sometimes I ring my friends , call not connet fast .it says all lines are busy. I feel jio is not good for ringing someone.
Sms option is good .you can send unlimited sms without any issues . Internet is good for whatsapp. Chatting on fb.and it is also good for downloading. Files are downloaded imadiately. For browsing it is excellent. I use jio sim because it has unlimited plans. If you want to get unlimited plans you can buy.
