Visiting the UK and Ireland on one trip: do you need one eSIM or two?

Combining the UK and Ireland into one trip is common — a long weekend that covers London and Dublin, or a longer loop through both countries. Since they're separate destinations for eSIM purposes, it's worth thinking through whether to buy one plan or two before you fly.

Why they're treated separately

The UK and Ireland are distinct destinations with their own mobile networks and, for BrisqNet, their own country plans. A UK eSIM plan doesn't automatically cover Ireland, and vice versa, unless you're specifically on a regional plan that includes both.

When two country plans make more sense

If you're spending most of your trip in one country with only a short visit to the other, two separate country plans — sized appropriately for the time in each — is often simpler and more cost-effective than paying for broader regional coverage you'll barely use.

When a regional plan makes more sense

If your time is split more evenly between the UK and Ireland, or your itinerary crosses back and forth, check whether a BrisqNet regional plan covers both — that avoids switching plans mid-trip. Confirm exactly which countries a regional plan includes before you buy, since coverage varies by plan.

How to decide for your trip

• Map out roughly how many days you'll spend in each country
• Compare the price of two country plans against a regional plan that covers both
• Check the regional plan's included countries carefully — not every regional plan includes every nearby destination
