eSIM vs roaming vs local SIM
Three ways to get mobile data abroad: keep roaming on, buy a local SIM at your destination or install a travel eSIM before you leave. The right choice depends on where you go and how long you stay.
Inside the EU roaming is included in most European contracts, so it stays the simplest option. Outside the EU a travel eSIM is almost always cheaper than roaming and easier than a local SIM, because you install it before departure, keep your own number and pay one fixed price.
When roaming still wins
Travelling within the European Union on a European contract, roam like at home rules apply and your bundle works abroad at no extra cost. Check your fair use limit for long stays.
When a local SIM makes sense
For stays longer than a month in one country a local subscription can be cheaper per gigabyte. The trade off is registration with ID, a queue at the shop and a second phone number your contacts do not know.
When a travel eSIM is the best choice
- Trips outside the EU from a few days to a few months
- Multi country trips where one regional bundle covers everything
- Business travel where you must be online the moment you land
- Anyone who wants to keep their own number reachable

FAQ
Is roaming free everywhere in Europe?
Roam like at home covers the European Union plus Norway, Iceland and Liechtenstein. Switzerland, the United Kingdom and Turkey are outside that rule and depend on your operator.
Can I combine an eSIM with my normal SIM?
Yes. Keep your physical SIM for calls and texts, and set the eSIM as your mobile data line.
How do I avoid roaming charges completely?
Turn off data roaming on your physical SIM in your phone settings, and use the eSIM as the only data line.
Is eSIM data slower?
No. An eSIM uses the same local 4G and 5G networks, the profile is only a different way of storing the SIM.
