Mobile broadband data usage

[Chadstap]

Using the 4G mobile broadband service for over a year, but in the past week i have seen some very unusual high data usage...an extra 5-10 Gb per day ?

 Checking the details in the App i can see these data drains are all listed under the heading “other” and not any obvious cause such as browsinf, Netflicks, Amazon. Etc .

 Why is this happening , and what is “Other” data usage ?

Just in case maybe change you wifi password.

What does your phone (not the Optus App) say about the data usage?

Don't know what type of phone you have, but On Android phones you can see data usage itemised per app.
