I get charged for intenet browsing even when I have not used internet on the phone

[Sam08p8]

I get the following charge repeatadly

12/01/19     18:20PM    INTERNETBROWSING    00:00:00    $2.00

How can they charge for less than 1 second internet browsing.

I am on a long expiry plan to save money, But it cost me more than $60 a month.

Check setting on your phone.

*turn off background app refresh

*turn off automatic updates

*turn off data and just turn it on when you need to use it

When I set my phone to "Data Saver", meaning app background  traffic will only use wi-fi, there is a disclaimer that 1 app still uses mobile phone data ... I don't know which.

So those 365-day plans are only suitable for classic candy bar phones. Maybe consider the Optus resellers, you might find a cheap plan for 90 days with a token 500 MB that would cover your mystery internet access.
