More borders. Fewer SIM changes.

Match the country list to your route
A plan labelled Europe does not necessarily cover every European country. Check each stop, including transit stops. Do not assume Switzerland, Türkiye or the UK are included.
Allow for the full trip length
Compare validity and the activation trigger with your arrival and departure dates. Consider whether a single regional package is more convenient for your route than separate local plans.
Check the rules for your needs
Hotspot, network access and fair-use rules vary by plan. Read the full terms if you depend on tethering a laptop or need large amounts of data.
Keep a small offline toolkit
Download tickets and a map before crossing borders. Keep your installation instructions accessible, and avoid deleting an eSIM until your provider confirms whether it can be installed again.
