An eSIM Setup for Digital Nomads

2026-06-09 · 4 min read · updated 2026-10-09

For a nomad, mobile data is work infrastructure: a backup when the co-working Wi-Fi drops, a hotspot for the laptop on a travel day, and the line that gets you to your next flat. The setup below keeps your home number working for security codes, sizes data for a month at a time, and avoids paying for more than you use.

The two-line setup

Run two lines on one phone:

• Home line (physical SIM or eSIM): kept on for calls and texts, mainly so bank and two-factor codes keep arriving. Data roaming off. Check what your carrier charges to receive texts abroad, and whether it offers Wi-Fi calling.
• Travel eSIM: set as the mobile data line, with data roaming on for that line only. Most plans are data-only, so calls go through WhatsApp, Signal or similar.

Before you rely on that, check your phone supports eSIM and is carrier-unlocked on the device list. Keeping your number abroad covers the messaging side.

Sizing a month

Our plan recommender uses three daily rates: 0.2 GB a day for maps and messaging, 0.5 GB for social media and photos, and 1.3 GB for streaming or hotspot use. It then adds 15% headroom so you don't run dry on the last day.

Nomad months are a mix. Work out how many days fall into each kind:

• Wi-Fi-first month: you work on co-working or flat Wi-Fi and use mobile data for maps and messages. 30 × 0.2 = 6 GB, about 6.9 GB with headroom.
• Normal month: socials, photos, some calls on data. 30 × 0.5 = 15 GB, about 17.3 GB with headroom.
• Mixed month: 24 normal days and 6 hotspot days for travel or a Wi-Fi outage. 24 × 0.5 + 6 × 1.3 = 19.8 GB, about 22.8 GB with headroom.
• Hotspot-first month: mobile data is your main connection. 30 × 1.3 = 39 GB, about 44.9 GB with headroom. That's unlimited territory, with the daily high-speed cap shown on the plan.

Hotspot use deserves a warning of its own. Most plans allow sharing, but it depends on the local network. Check the plan details before you rely on it, and budget data at the streaming rate. If your income depends on it, have a second option: a co-working day pass, or a café you've already tested.

Choosing the plan

• Staying a month in one place: a country plan, for example Portugal, Thailand or Mexico. The destination guide, such as the Thailand guide, shows networks and coverage.
• Moving through one region: a regional plan such as Europe or Asia.
• Crossing regions: Global.

Country, regional or global has decision rules if your route is somewhere in between.

Running it month to month

• Nothing auto-renews. No plan rolls over and charges you while you're on a beach between contracts. You decide each top-up.
• Top up rather than oversize. Buy close to your estimate and top up from your account when you run low. This suits uneven months better than buying the largest plan every time.
• Buy the next plan early. Validity starts when the phone first connects in the destination, so you can install next month's plan on good Wi-Fi before you travel.
• Know the refund rule. If an eSIM never connects, you get a full refund to the method you paid with. Once it has connected, the plan counts as used. See the refund page.
• Keep receipts. Every purchase has a receipt, which helps if you expense connectivity.

Longer stays

If you settle somewhere for several months, a local contract can make sense once you have an address. Until then, an eSIM covers the gap. eSIM vs local SIM compares the two.

A short pre-departure list

1. Phone unlocked and on the device list.
2. Data estimate for the month, from the rates above.
3. eSIM installed on Wi-Fi, set as the data line.
4. Home line data roaming off, texts working.
5. Offline maps and a backup Wi-Fi plan for work days.
