It is pretty easy to find out the remaining Jazz 3G internet MBs through your account. You just have to add *2# at the end of the subscription code of your subscribed package.
Let’s see an example:
If you are using a weekly jazz internet package with the subscription code: *117*47#.
You can check the remaining internet MBs on the weekly internet package by adding *2# to it.
This will become: *117*47*2#
Note: The actual subscription code was: *117*47
Similarly, if you are using Jazz monthly premium internet package, then you can check the remaining internet bytes by dialing *117*30*2#. Here, *117*30 is the code for a monthly premium package by the telecom network.
