Common questions
Will my eSIM work in Lisbon, Porto, Algarve?
Yes. All major cities and beach towns have strong 4G coverage. Small villages and rural areas also covered reliably.
How about mountain hiking (Peneda-Gerês)?
Coverage is solid on main mountain routes. More remote trails may have spotty coverage, but most hiking areas near trails have adequate signal.
Do I need an eSIM or just roaming?
EU roaming rules let you use home SIM at domestic rates, but eSIMs are cheaper and let you keep your home number active.
