Three months abroad: travel eSIM or a local SIM?

A travel eSIM is built for trips: days or weeks, no paperwork, nothing to return. Stay for months and the maths changes, and so does what you need. Here is where we think the line sits, including the part where a local SIM wins.

What changes after a few weeks

You need a local number. Not for calling friends, but for the country's everyday plumbing: delivery drivers, banks, the gym, a landlord, the two factor code from a local service. A travel eSIM is data only, so it cannot do this.

Your consumption goes up. Living somewhere means using data like a resident, not like a tourist who is out all day. Local plans are priced for that.

Local prices are for locals. In many countries a monthly plan with tens of gigabytes costs less than a fortnight of travel data.

When the local SIM is the right answer

• You are staying three months or more in one country.
• You need a local number for services, paperwork or deliveries.
• You can get one: some countries need a residence document, a tax number or an in person registration. Check that before you land, because it is the step that surprises people.

When the travel eSIM still wins

• The first days. You land, you need to be online immediately, and you cannot buy a local SIM at seven in the morning on a Sunday. Use a short travel plan while you organise the rest.
• While your paperwork is pending. If the local SIM needs a document you do not have yet, a travel plan covers the gap without a contract.
• If you will move around. A term in Spain with weekends in Portugal and France, or a season spent between two countries, is a regional plan's natural habitat.
• If you want your own number to keep working, which it does: the travel eSIM handles data, your home line keeps receiving your bank's messages.

The setup we would use for a term abroad

1. A travel plan for the first week, installed at home.
2. A local SIM once you are settled, for the number and the monthly data.
3. Keep the travel eSIM installed for trips out of the country, where the local plan may roam badly or not at all.
4. Keep your home line in the phone, with data roaming off, so your usual number still receives codes and calls.

That is three lines on one phone, which any recent phone handles.

Quick answers

Can I keep extending a travel plan instead?

You can top up the same eSIM, and for a month or two that is reasonable. Past that, a local plan is usually cheaper and gives you a number.

Will I lose my home number?

No. It stays in the phone as a second line. Keep its data roaming off and it costs you nothing to keep receiving texts.

What about countries where a local SIM is hard to get?

Japan and India are the usual examples for short term visitors. There a travel eSIM often remains the practical answer well past the point where it would be in Europe.
