Capitec international travel usage

Hi guys

Recently signed up for Capitec for an upcoming trip in a week's time.

I will be using it to mainly withdraw cash from the international ATM.

For people who have used this card overseas, how do I notify them that I'll be traveling? Do I just need to say allow for international transactions on the app. Is there any other settings on the app or do I need to visit bank?

When overseas I will be using an esim so I will have access to internet but won't have access to my +27 number. Will this have an impact on bank card usage?

Thanks
