Internet access while travelling can be priceless — for maps, a translator and bookings. An eSIM abroad is today the most convenient way to stay online without hunting for a kiosk selling a local card.
What an eSIM is
An eSIM is a digital SIM loaded onto your phone via a QR code — no physical card. You buy a data plan for a country or region online and activate it before you even fly.
When an eSIM pays off
Most of all outside the EU, where roaming on a home plan can be very expensive. Within the EU, roaming included in your domestic plan is often enough — check that before buying anything extra.
How to choose a data plan
Estimate your usage: maps and messengers use little, streaming and video use a lot. For most trips a few GB is enough; topping up later is often easy, so do not overpay upfront.
Check your phone and have a plan B
Make sure your phone supports eSIM and is not carrier-locked. Save your key maps and addresses offline — useful when you lose signal.
Online = easier navigation
Constant internet makes finding your way easier — more in our guide on how not to get lost in a foreign city. Include the data cost in your budget for payments abroad. Save your route in TRAMFI.
Frequently asked questions
Does an eSIM work alongside my own number?
Yes — dual-SIM phones keep your home number for calls while the eSIM handles data. It is a convenient setup for a trip.
eSIM or a local SIM card?
eSIM wins on convenience and activation speed. A local card can be cheaper for a longer stay but requires buying it on the spot.
