Get a Holafly eSIM →What is Holafly?
Holafly is an eSIM provider offering mobile-data plans for 200+ destinations. An eSIM is a digital SIM you install by scanning a QR code — no physical card and no store visit. You buy your plan in advance and activate it when you arrive, while keeping your existing SIM in the phone.
Why an eSIM helps when moving to Portugal
In your first days in Portugal you need data before you have sorted a local plan — for maps, rideshares, bookings and staying in touch. A travel eSIM gets you online instantly on arrival and bridges the gap until you set up a local SIM or residency line.
Install before you fly
Buy online, scan a QR code, and your eSIM is ready to activate on arrival.
Data in 200+ destinations
Plans covering most countries, including generous and unlimited-data options.
Keep your own number
Runs alongside your existing SIM, so your usual number stays in the phone for calls and texts.
Who Holafly is for
Travellers and new arrivals who want data the moment they land — house-hunting trips, the first weeks after moving to Portugal, or anyone who would rather not queue for a local SIM at the airport. For keeping your US line reachable too, pair it with Tello.

What to keep in mind

- Holafly plans are primarily data — many do not include a local phone number for calls or SMS, so pair it with your usual SIM or a local number.
- It is a travel and arrival data solution; for a long-term local plan you may still want a local SIM once settled.
- Check the specific plan for your destination before buying.
