Jio has been offering unlimited data on many of its tariff plans, but those plans have Fair Usage Policy (FUP) which when exceded can lead to lower data speeds. So it's always better to keep a track of your data usage. The data usage you see in your phone's settings is not accurate, rather it's recommended to check data usage directly from the Jio servers. Here are the steps one needs to follow to check data balance: How to check the data balance on your Android or iOS smartphone: Download and install the MyJio app Open the MyJio app Tap on Sign in with SIM Tap on the Balance tab Here you can check how much data you have remaining and in how many hours it will renew in. You can also further tap on the Usage tab to get more details.

However, if you are still struggling to save data, here is something you can do to prevent wastage of mobile data. On Android smartphones Go to your mobile data options and find the data usage tab.
