Question about internet package data usage calculation

Hello everyone,

I am an Orange customer and currently using a 9GB internet package. Since December 6, I activated this package, and on December 28, I activated a new 9GB package.

My phone's mobile data function shows that I have used only 7.68GB, but my first 9GB package has been fully consumed.

I am curious about how Orange calculates the data consumption. Is it possible to get a detailed report or explanation of how the usage is calculated?

If anyone has faced a similar issue, I’d appreciate any advice or help.

Best regards,

Volodya Simonyan
