eSIMs for digital nomads and long stays: monthly plans, top-ups and when to go local
How to handle mobile data over months abroad — long-validity plans, monthly plans that renew on the same eSIM, top-ups versus buying a new eSIM, and when a local SIM is the better answer.
· 8 min read
For stays of a month or more, the simplest setup is one travel eSIM per country that you keep topping up, rather than a new eSIM every few weeks. In Cabin Mode you can do that by hand or put an eligible 30-day line on an optional monthly plan: the same data and 30 more days are added to the same eSIM each month, a few days before it would run out, and you cancel in the app when you move on. For stays of many months in one country, or if you need a local phone number, a local SIM is often cheaper. The rest of this post covers the options and the numbers.
Prices below are from the Cabin Mode catalog, checked 25 September 2026, in USD. The app shows them in your own currency.
Three ways to stay connected for months
| Approach | Works best for | Watch for |
|---|---|---|
| One long-validity plan | 2–6 months in one country or region with predictable use | Paying for a large allowance up front |
| A 30-day plan that renews monthly | Open-ended stays, or when you don't know when you'll leave | Remember to cancel when you move on |
| Buy a local SIM | Six months or more in one place, or needing a local number | Paperwork, registration rules, a physical SIM slot |
Option 1: a long-validity plan
Some destinations have plans that last 90 or 180 days. For a stay of known length, one purchase covers it.
| Destination | Plan | Price |
|---|---|---|
| Japan | 50 GB, 180 days | $56.00 |
| United States | 20 GB, 90 days | $28.54 |
| United States | 50 GB, 180 days | $70.00 |
| Italy, Spain or France | 50 GB, 180 days | $44.00 |
| Europe (41 countries) | 20 GB, 90 days | $68.00 |
| Europe (41 countries) | 50 GB, 180 days | $156.00 |
That's a good deal if your usage is modest and you're mostly on Wi-Fi at home or in a co-working space. 50 GB over six months is under 300 MB a day, which is fine for maps, messages and email but not for someone tethering a laptop every day. Japan plans, Europe plans, United States plans.
If you run short, top up. It adds data to the same eSIM.
Option 2: a monthly plan on the same eSIM
If you don't know how long you're staying, a 30-day plan that renews each month avoids both overbuying up front and scrambling for a new eSIM every four weeks.
How the Cabin Mode monthly plan works:
- It's available on eligible 30-day lines. In the app, destinations that have them show a Monthly option alongside one-off plans. Plans have to last about a month and support top-ups to be eligible.
- You pay the first month when you buy, then the same price each month at the rate fixed when you start. The checkout shows the next charge date.
- Each month tops up the same eSIM with the plan's data and 30 more days. It happens a few days before the current period would end, so the line never lapses. Data and validity stack, so anything left over carries into the next period.
- Nothing new to install. Same eSIM, same settings, same line on your phone.
- Cancel any time in the app. You keep the data you've already paid for, and the eSIM keeps working until its validity ends. Nothing renews after that.
You can also start a monthly plan later on a line you already have, if the line supports it. It's under the eSIM in the app.
What it costs, with monthly-eligible 30-day plans as examples:
| Destination | 10 GB / 30 days | 20 GB / 30 days |
|---|---|---|
| Japan | $9.40 | $16.40 |
| Thailand | $9.40 | $16.40 |
| Portugal | $8.56 | $16.40 |
| Spain | $8.56 | $16.40 |
| United States | $13.26 | $24.86 |
Thailand plans, Portugal plans, Spain plans.
Top-ups vs a new eSIM
When you run low or near the end of the validity period, you have two choices.
Top up the same eSIM when:
- You're staying in the same country or region.
- The plan hasn't expired yet. A top-up can't revive an expired plan.
- You want to keep your settings and labels as they are.
Buy a new eSIM when:
- You're moving to a country your current plan doesn't cover.
- The plan has already expired.
- You want a different kind of plan, say moving from a daily plan to a fixed one.
A new eSIM means a new install, so do it on Wi-Fi. Deleting the old one first isn't necessary. iPhones hold eight or more eSIMs, and an expired one can simply be deleted when you get round to it. Can you reuse or delete a travel eSIM covers that in more detail.
How much data does a nomad need?
Much more variable than a holiday. It depends mostly on whether your accommodation and workspace have reliable Wi-Fi.
| Setup | Rough monthly use |
|---|---|
| Good Wi-Fi at home and co-working, phone for maps and messages | 5–10 GB |
| Some work outside on mobile data, occasional video calls | 15–30 GB |
| Mobile data as main internet, tethering a laptop daily | 50 GB or more |

Keeping your home number alive
On long trips, your home line matters more than on a holiday. Bank codes, WhatsApp reverification and account recovery texts all go to it.
- Keep the home line switched on with Data Roaming off. SMS still arrives. Keeping WhatsApp and bank codes abroad has details.
- Check your home plan stays active. Some prepaid numbers expire after months without a top-up or use. Know your carrier's rules.
- Consider a cheaper home plan. Some carriers offer low-cost plans that keep a number active while you're away. Worth asking before you go.
- Move 2FA to an authenticator app or passkeys where your bank and accounts allow it. Fewer SMS codes to worry about.
When a local SIM is the better answer
A travel eSIM isn't always the right answer on a long stay:
- You need a local phone number. Some countries' banking apps, delivery services, ride-hailing and landlords expect one. A travel eSIM is data only.
- You're staying six months or more in one country. Local prepaid plans can be very cheap per GB, and the paperwork is a one-off.
- You need unlimited home-style data. Local operators sometimes offer truly unlimited plans to residents.
Registration rules vary: many countries require a passport or residence permit to buy a local SIM. If your iPhone is eSIM-only (all US iPhones from the 14 onwards, for example), you'll need a local carrier that offers eSIM. Which iPhones support eSIM lists the eSIM-only models.
A common pattern: use a travel eSIM for the first few weeks while you settle in, then switch to a local SIM if you decide to stay. You're online from day one without having to sort out a local plan in a language you're still learning.
Fair use on long stays
Travel eSIMs are made for travel. Using one permanently in your home country, or in a way designed to get around an operator's traffic policies, can lead to the line being suspended. Using one for months while you're genuinely abroad is exactly what they're for.
A practical setup for a multi-country year
- Before each move, look at the next country's plans and decide between a long-validity plan, a monthly plan, or a regional plan if you'll be crossing borders. Regional vs country eSIM compares the last option.
- Install the next eSIM on Wi-Fi before you travel.
- When you arrive, switch the data line and turn Data Roaming on for the new line.
- Cancel the previous country's monthly plan in the app, if you had one.
- Delete expired eSIMs from Settings › Cellular now and then, so the list stays manageable.
Frequently asked questions
What's the best eSIM for long stays abroad?
It depends on how long and how sure you are. For a stay of known length, a 90- or 180-day plan is simplest. For an open-ended stay, a 30-day plan on a monthly renewal keeps the same eSIM topped up. For six months or more in one country, compare a local SIM.
Can I top up a travel eSIM instead of buying a new one?
Yes, as long as it hasn't expired and the plan supports top-ups. In Cabin Mode, a top-up adds data to the same eSIM, with nothing to reinstall.
How does the Cabin Mode monthly plan work?
On eligible 30-day lines, you pay for the first month when you buy, then the same price each month. A few days before each period ends, the plan's data and 30 more days are added to the same eSIM. Cancel any time in the app; the eSIM keeps working until its validity runs out.
Will my travel eSIM expire if I don't use it?
Once a plan has started, its validity counts down continuously, used or not. A plan that has never been activated doesn't expire on its own, though the operator can withdraw the package; if that happens before you activate, you're refunded.
Do digital nomads need a local SIM?
Not always. A travel eSIM covers data for most people. A local SIM makes sense if you need a local phone number or you're staying six months or more in one place.
Can I keep my home number while living abroad?
Yes, as long as your home line stays active. Keep it switched on with Data Roaming off, so SMS codes still arrive, and check your carrier's rules for keeping the number active.
