eSIMs, Roaming and Staying Connected Abroad

Connectivity has become an operational part of travel rather than a convenience. Tickets, boarding passes, maps, translations and accommodation check-in codes all live on a phone, which makes the data plan a genuine planning decision.

If you travel within the European Union with an EU contract, roaming is usually included at domestic rates and no action is needed. Travellers from outside the EU, and those visiting non-EU countries such as Switzerland, the United Kingdom or the Faroe Islands, should check the per-day roaming rate carefully, since it can quietly exceed the cost of a week of accommodation.

eSIMs are now the simplest solution for most phones purchased in the last few years. A regional plan can be bought and installed before departure, activates on arrival, and keeps your usual number reachable over the physical SIM. Buy modest data volumes first; regional plans are easy to top up and hard to refund.

Physical local SIMs still make sense for long stays, high data usage or for travellers who need a local number for calls, parking apps or delivery services. They typically cost less per gigabyte but require an in-country shop visit and sometimes identity registration.

Whichever option you choose, prepare for the moment there is no coverage at all. Download offline maps of the whole region, save accommodation addresses and booking references offline, and keep a screenshot of key tickets. Mountain valleys, island interiors and rural coastal roads regularly have no usable signal.

Finally, carry a power bank of at least 10,000 mAh and a charging cable in your day bag. Navigation, photography and translation drain a battery fast, and a phone at two percent is functionally the same as no connectivity at all.
