eSIM or roaming: which is cheaper in 2026

We work out the cost of a week of data abroad: your home carrier's roaming versus a travel eSIM. Spoiler: the difference can be several times over.

Roaming is convenient: nothing to set up and you keep your number. But outside “home” zones it usually costs noticeably more than a travel eSIM — especially if you need a lot of data.

When an eSIM is better value

  • You need more than 1 GB of data on the trip.
  • Your carrier has no good-value packs for the destination.
  • You need to share data with a laptop or tablet.

When roaming will do

  • Calls and texts on your main number matter most, and you need very little data.
  • Your carrier offers a good-value pack for that specific country.

💡 Tip: The best option is to combine them: keep your main SIM for calls and texts (with data roaming off) and use a travel eSIM for internet.
