-5% on your 1st eSIM
WELCOME5
The best eSIM for a digital nomad is a regional or long-validity plan that allows hotspot use, sits next to your home line rather than replacing it, and can be topped up without a new install. Before price, check three things: the countries on the plan, its hotspot rule, and the upload speed of the networks it uses.
Key takeaways
- Upload speed decides whether a video call holds: Zoom asks for 2.6 Mbps up for a 720p group call
- A regional plan covers a loop of neighboring countries on one eSIM, and you top it up instead of reinstalling
- On iPhone, Personal Hotspot shares whichever line carries cellular data, so the travel eSIM has to be that line
- Keep your home number on a second line for bank codes, with its data roaming switched off
- An EU SIM used abroad for months can trigger the operator's fair use check, which looks at a four-month window
Upload Speed Decides Whether Your Calls Hold
Speed tests and plan pages lead with download figures, but a remote worker's day is limited by upload. Zoom's system requirements list 1.2 Mbps up and down for a 720p one-to-one call, 2.6 Mbps up and 1.8 Mbps down for a 720p group call, and 3.8 Mbps up for 1080p. At the group-call rate, an hour of meetings can move close to 2 GB in both directions combined, which is why a working month needs far more data than a holiday week.
Average upload speeds on the networks in popular nomad bases clear that bar, with wide gaps between countries. In nPerf's 2025 barometers, MEO averaged 36.82 Mbps up in Portugal and True Move H 24.24 Mbps in Thailand, while Telcel led Mexico at 10.12 Mbps with an average latency of 86 ms, against about 28 ms for the two Portuguese leaders. In Indonesia, nPerf's July 2025 to June 2026 barometer puts XL Axiata first on upload at 15.11 Mbps. These are national averages, not a promise for your apartment: the networks a plan connects to are listed in its details, and a window seat in a coworking space still beats a basement.
One Plan for the Whole Loop: When Regional Beats Country
Most nomads circle a region rather than settle in one country: Lisbon, Seville and Madrid in winter, Chiang Mai, Bali and Da Nang in Asia, Mexico City to Medellín when the visa clock runs down. A regional eSIM keeps one profile installed across that loop. When you cross a border, the phone joins a network in the next country on the plan's list and the data keeps flowing.
Read the country list in the plan details before you commit, because regional names hide gaps and the list is what counts. A country plan makes more sense once you stop moving: two months in one city is usually better served by a plan for that country, topped up on the same eSIM when the allowance runs low, than by paying for coverage you are not using.
Hotspot: Where Most Nomad Setups Break
Your laptop works through your phone more often than you expect: a café router that blocks video, an Airbnb connection that dies at 9am, a train between cities. Hotspot availability on a Simsima eSIM depends on the plan, so check it, or ask support, before you buy if your laptop will depend on it.
On iPhone, set it up under Settings > Cellular > Set Up Personal Hotspot. If you run two lines, Apple's guide is explicit that Personal Hotspot uses the line selected for cellular data, so the travel eSIM must be that line or your laptop will roam on your home plan. On Android, the Hotspot tile sits in Quick Settings, and Google's help page notes you can share mobile data with up to 10 devices, and that some carriers limit tethering. A laptop on a hotspot behaves like it is on home broadband, so pause cloud backups and large syncs before you share.
The Two-Line Setup: Home Number for Codes, Travel eSIM for Data
A Simsima eSIM is data only, with no phone number. Your usual number stays on your main SIM, where bank one-time codes, government portals and delivery drivers can still reach it. Apple's Dual SIM page confirms that both numbers can make and receive calls and texts while only one line carries cellular data at a time.
- Install the travel eSIM over Wi-Fi before you fly, and label the two lines Home and Travel
- Under Settings > Cellular > Cellular Data, choose the Travel line
- Turn Data Roaming off on the Home line and on for the Travel line
- Leave Allow Cellular Data Switching off while abroad: Apple warns it can draw data from the other line, with roaming charges if that line has Data Roaming on
- Turn on Wi-Fi Calling for the Home line if your carrier supports it, so it can receive calls over Wi-Fi
Texts to your home number still arrive with data roaming off, because SMS does not use mobile data. Whether your carrier bills incoming texts or calls abroad depends on your plan, so check before a long stay.

Living on an EU SIM: the Four-Month Fair Use Check
Nomads who keep a European contract often rely on roam like at home. The rules cover the EU, Iceland, Liechtenstein, Norway, Moldova and Ukraine, but they are built for periodic travel. According to the EU's Your Europe roaming page, an operator may look at a four-month period, and if you spent more time abroad than at home and roamed more than you used domestically, it can ask you to explain within 14 days and then add capped surcharges. Outside those countries, the regime does not apply at all, which is where a travel eSIM for data earns its place.
When a Local SIM Beats a Travel eSIM
Past two or three months in one country, a local prepaid or postpaid plan starts to make sense. It brings a phone number in that country, the kind delivery apps, landlords and some banks expect and a data-only eSIM cannot provide. The cost is paperwork: Apple's travel eSIM guide notes that you may be asked for identification such as a passport, and that a postpaid account can require proof of local residency, a bank account or a credit card.
Many nomads arrive on a travel eSIM, settle in for the first month, then decide. If you do switch, keep the travel eSIM installed as a backup line for network outages and visa runs: you can top it up later rather than buying a new one.
A Nomad's Checklist Before You Pay
- Every country on your next three months of route appears in the plan's country list
- The plan's hotspot rule fits a laptop day, confirmed before purchase
- The networks listed for your main base have upload speeds to match your calls
- Validity covers your stay, and the plan can be topped up on the same eSIM
- Your phone is unlocked: on iPhone, Settings > General > About shows No SIM Restrictions next to Carrier Lock
- Your home line keeps calls and texts, with its data roaming off
Support, Deleted Profiles and Planning Offline
Simsima covers 190+ destinations, with country plans for long single stays and multi-country Trip Packs for regional loops. Support usually replies within 24 hours, and a deleted eSIM cannot be reinstalled on your own, so contact support rather than removing a profile you might still need.
Connectivity is only half of the stack. The other half is knowing where you are going and having that survive a dead zone. Wanderlog is a trip planner many nomads use: you build a day-by-day itinerary, drop in flights and accommodation bookings, and it stays available offline once downloaded, which matters on the leg between landing and getting a profile installed. If you are moving with other people, they can edit the same plan with you in real time and leave notes on it. Free to use, with a paid tier for offline maps.
Frequently Asked Questions
Usually, on a 4G or 5G network with decent signal. Zoom's published requirements top out at 3.8 Mbps up for 1080p video, and nPerf's 2025 national averages for the leading networks in Portugal, Thailand and Mexico are all above that. What breaks calls is a weak signal in your specific room, so test from where you will work.
It depends on how many hours you spend on video. Email, chat and documents use little, but an hour of 720p group calls at Zoom's listed bandwidth can approach 2 GB. If calls fill several hours a day on mobile data, plan for tens of gigabytes a month or a plan that can be topped up. Simsima's data usage calculator gives a quick estimate.
A digital SIM built into the phone. You install a plan by tapping a link or scanning a QR code instead of inserting a card, and supported iPhones can store eight or more eSIMs, with two active at once.
A country plan stops working once you leave that country. A regional plan keeps working if the new country is on its list, and the phone connects to a local network on arrival. A regional or Global plan also activates directly if you install it while already inside its zone.
Yes. Supported iPhones store eight or more eSIMs, and from the iPhone 13 two can be active at once; Pixel 7 and later can also run two eSIM profiles where the carrier allows it. You choose the data line in settings without reinstalling anything.
No. An eSIM is only a data connection and has no bearing on tax residency, which depends on your visa, the time you spend in a country and its own rules. Ask an accountant who handles cross-border remote work.
