Which focus does my automatic top-up receive?

Every following automatic top-up is based on your last Focus bundle. In other words, if today you go for the Focus bundle with more data, in the future the same bundle will be topped up every month. Until you would switch to a different bundle, obviously. In which case that bundle would become the default. This is also the case if you top up using the My Viking app.
