I’m on Unlimited Premium with my line on Dark Star, and I have a Europe trip coming up in a few weeks. I’m flying into Portugal first, then heading to Italy, then back home. I need my US number to stay working the whole time for calls, texts, and data.
My plan is to set my roaming destination to Portugal before I leave. What I’m not sure about is the move from Portugal to Italy: do I need to go back into the app and switch the destination to Italy, or will it carry over on its own since both are full talk/text/data countries?
Has anyone done a similar two-country trip recently? Just want to confirm it’ll work before I go. Thanks in advance.
