Month four of continuous travel, I made a spreadsheet.
Not a budget spreadsheet. Not a packing list. A spreadsheet tracking every connectivity decision I had made across seventeen countries, what it had cost, how long it had taken to sort, and whether it had actually worked when I needed it to.
The results were embarrassing.
In seventeen countries, I had paid roaming charges in four, bought local SIM cards in nine, relied entirely on accommodation WiFi in two, and used a travel eSIM in two. The roaming charges were the most expensive by a significant margin. The local SIM cards were the most time-consuming — an average of forty-seven minutes per country between finding a carrier store, completing registration, and activating the plan. The eSIMs were the cheapest and took an average of six minutes each to set up.
I finished the spreadsheet, closed it, and started using eSIMs for every country from that point forward.
Why Connectivity Is Different for Long-Term Travellers
Short-term travellers can afford to improvise. A week in one country with acceptable hotel WiFi and occasional café hotspots is manageable. The connectivity decisions are simple, the stakes are relatively low, and the time cost of getting it slightly wrong is measured in hours rather than days.
Long-term travel operates on different economics entirely.
When you are moving between countries every few weeks for months at a time, the cumulative cost of daily roaming charges becomes a significant line item in your annual budget. The cumulative time cost of buying local SIM cards in every new country — finding the right store, navigating registration processes in languages you may not speak, troubleshooting when activation fails — adds up to days of lost productivity over the course of a year.
And for digital nomads specifically, connectivity is not a travel amenity. It is the infrastructure that makes the entire way of life function. Video calls with clients, cloud-based work, uploading content, accessing remote servers — all of it depends on reliable, consistent mobile data that works predictably across every country on a continuously changing itinerary.
The question for long-term travellers is not whether to think about connectivity. It is how to stop thinking about it. How to build a system that works reliably enough that you can direct your attention to the actual reasons you are travelling and working this way.
The Evolution of How Digital Nomads Handle Connectivity
When I started travelling continuously, the standard advice in nomad forums was straightforward: buy a local SIM in every country. It was true that local SIMs offered the best data rates. It was also true that the forty-seven minute average I calculated did not account for the times when registration failed, when the SIM did not activate properly, or when I arrived in a country late at night with an urgent client call the following morning and no carrier store open until nine.
The advice was optimised for cost. It was not optimised for reliability or time efficiency, which for people running location-independent businesses are often more valuable than the marginal saving on data costs.
Over time, most of the long-term travellers I know have moved to a hybrid approach that prioritises minimising connectivity friction rather than minimising data cost:
Travel eSIM for short stays and multi-country periods
For countries where you are spending less than three weeks, or for periods where you are crossing borders regularly, a regional or international eSIM eliminates the setup overhead entirely. Install before you travel, activate when you land, and your connectivity works across multiple countries without any further action.
The key factor for nomads is coverage breadth. A plan that covers the countries you plan to visit plus reasonable flexibility for itinerary changes — because nomad itineraries always change — is more valuable than the cheapest plan that covers only your confirmed destinations.
Local SIM for extended stays
For countries where you are spending a month or more, the economics shift toward local SIMs. The setup time is a one-time cost that amortises across thirty or more days of significantly cheaper data. For nomads who work heavily from a single base for extended periods, local SIMs remain the most cost-effective option.
Accommodation WiFi as supplement, not primary
The nomad instinct to treat accommodation WiFi as the primary connectivity source and mobile data as a backup is one that experienced long-term travellers largely abandon. Accommodation WiFi is unreliable in quality, often congested, sometimes non-existent in the type of accommodation that nomads frequently prefer, and completely unavailable for anything that requires being away from your base.
Reliable mobile data as the primary connectivity source, accommodation WiFi as the supplement, is the approach that actually works for location-independent work.
What Matters When Choosing an International eSIM for Long-Term Travel
The criteria for nomads are different from the criteria for tourists.
Coverage breadth over coverage depth
A tourist knows exactly where they are going. A nomad knows approximately where they are going, with significant scope for change. An eSIM plan that covers forty countries rather than twenty is more valuable for a nomad than one that offers slightly better rates in the specific ten countries on a confirmed itinerary, because the confirmed itinerary will not survive contact with reality.
Fixed data over unlimited for professional use
This distinction matters more for nomads than for any other traveller category. Unlimited plans operate under fair use thresholds — typically a daily cap after which speeds reduce significantly. For leisure browsing, throttled speeds are inconvenient. For a video call with a client, or for uploading a large file on a deadline, throttled speeds are professionally damaging.
Fixed data bundles deliver every gigabyte at full network speed. Predictable performance throughout your allowance is more valuable than the theoretical label of unlimited, particularly when the work you are doing depends on that performance.
Validity periods that match nomad timelines
Short validity periods — seven or fourteen days — are designed for tourists. Nomads need thirty-day validity as a minimum, with the ability to install in advance and activate when they arrive in a covered country. A plan purchased two weeks before departure should still be valid when you land.
Top-up availability without switching plans
Running out of data mid-month and being able to purchase additional gigabytes on the same eSIM without reinstalling anything is a practical requirement for nomads who use data heavily for professional purposes.
After the spreadsheet revelation, I spent time comparing options against these criteria specifically. I settled on easySim for international periods primarily because of coverage breadth and fixed data performance. The international plans cover the range of countries I move through, the data delivers full speed throughout the allowance, and the thirty-day validity with advance installation means I can purchase weeks ahead without the plan expiring before I activate it.

Practical Connectivity Habits That Actually Make a Difference
Beyond choosing the right plan, there are specific habits that separate nomads who manage connectivity well from those who are perpetually troubleshooting it.
Install before you arrive, always
The eSIM that is installed at home on a reliable connection is the eSIM that works when you land at midnight in an unfamiliar airport. The eSIM that you try to install on airport WiFi while tired after a long flight is the one that fails at the worst possible moment. Install before departure, without exception.
Disable roaming on your home SIM before you land
Your home SIM will attempt to connect to local networks the moment you land. Background apps — email, messaging, cloud sync — start consuming data at international roaming rates before you have consciously used anything. Disable roaming on your home SIM before you board, every flight, every country.
Download maps and key documents before going remote
The day before any remote section — a rural road trip, a coastal ferry journey, a countryside accommodation without WiFi — download offline maps for the entire route, save your accommodation address and booking confirmation offline, and download any documents you might need. Google Maps offline works without data. GPS navigation works without data. The preparation takes twenty minutes and prevents hours of problems.
Know your data consumption patterns
After six months of nomadic travel you will know exactly how much data a typical work day consumes, how much a video call costs, and how much headroom you need for unexpected usage. Before that point, track your daily consumption in your phone’s data settings for the first few months. The numbers are almost always different from what you assumed, and knowing them lets you choose plans accurately rather than guessing.
Have a backup connectivity option
The traveller who has only one connectivity plan has no backup when that plan fails. For nomads doing professional work, maintaining a secondary option — a backup eSIM, a known café with reliable WiFi near your base, a local SIM from a previous stay that still has credit — eliminates the professional risk of a single-point connectivity failure.
The Spreadsheet in Retrospect
I still have that spreadsheet. I updated it for another year after the point where I switched entirely to eSIMs for multi-country periods.
The time cost column dropped to near zero for connectivity setup across new countries. The cost column decreased significantly compared to the roaming years. The reliability column — which I had tracked subjectively as the percentage of times my connectivity worked when I needed it — improved substantially.
The goal of the spreadsheet was never to find the cheapest possible connectivity. It was to find the system that caused the least friction, cost the least time, and failed the least often. Those three criteria consistently pointed toward the same approach.
For nomads at the beginning of long-term travel who are still figuring out which connectivity approach works for their specific itinerary and working style, the comparison of travel eSIM options for trips abroad covers the practical differences between providers, plan types, and what to prioritise based on how you actually travel and work.
Sort the connectivity once, properly. Then stop thinking about it and use the time for everything else.
