Practical travel preparation

Best-practice travel preparation for 20 popular non-EU destinations

Check the things that change from one trip to another: official advice, entry requirements, mobile coverage, roaming terms, offline access and what your phone must do on arrival.

Start with your actual trip

Non-EU does not automatically mean you need an eSIM.

Your Irish plan may already include the destination, airport Wi-Fi may cover a short connection, or offline preparation may be enough. Check the exact country, tariff, fair-use terms, trip length and route before paying for another plan. For current safety and entry information, use the Department of Foreign Affairs travel-advice service.

“Top 20” here is a transparent editorial selection led by suitcase.ie’s current priority destinations and common long-haul trip-planning needs. It is not a tourism, popularity or search-volume ranking.

Read the current Department of Foreign Affairs travel advice for your destination.
Check passport, entry and transit requirements for your own citizenship and itinerary.
Confirm what your Irish mobile plan covers before buying more data.
Match any travel-data plan to both the allowance and the complete trip duration.
Save bookings, essential addresses and a usable offline map before departure.
Keep voice, SMS and authentication needs separate from a data-only eSIM decision.
