Smartphone calling numbers by itself

#1

Hi,

One time during my frequent US visits, my smartphone randomly called a long list of random Canadian numbers.

Thing is, the phone was rarely on and when it was, I made sure to only enable Wi Fi, no mobile data.

I have a British sim. I came home to an £80 charge. The random numbers were called without my knowledge.

Anyone else come across this?

Android by chance?

If so, I strongly suggest you open the settings and search for “Permissions”. In there you should find Telephone. This will list all apps which have access to your phone dialer.

Remove any that don’t look like they should be there.
