Does adding a travel eSIM mean my home line has stopped roaming?
TechnologyMy partner saw the travel plan installed on my iPhone and said, “Good, that's the phone sorted.” Two line names still appeared in Settings. I realised I did not know which one would carry data when we landed.
The travel eSIM is for an eight-day visit. I bought it for maps and messages, but I also want my usual number available for a call from the person looking after our cat. My partner suggested turning both roaming switches off, which sounds simple until I read that I need to follow the travel provider's own setup instructions.
Apple says a travel eSIM can be used by itself or alongside a home line, and keeping both active can still involve home-provider roaming fees. [Apple's travel guidance](https://support.apple.com/en-ie/118227).
What should I confirm before departure? I want one agreed setup rather than discovering at the airport that we each meant something different by “the travel SIM is on.”
