eSIM vs local SIM vs roaming
An eSIM wins on convenience and instant setup, a local SIM on price and a local number for long stays, and roaming on doing nothing at all — usually at the highest cost. For most nomads an eSIM is the default, with a local SIM taking over once you settle somewhere for a while.
The short answer
eSIM for convenience and short-to-medium trips, local SIM for the cheapest data and a local number on long stays, roaming only if your home plan makes it cheap. Start with our best eSIM guide.
eSIM — convenience and instant setup
An eSIM is the fastest way to land with working data. You buy and install it before you fly, switch it on at the airport, and never hunt for a shop or swap cards — and you can hold plans for several countries at once. The trade-off is a small premium over a local SIM and, on most travel plans, no local phone number (they're data-only). For short trips and country-hopping, that convenience usually wins. See how it works in what is an eSIM.
Local SIM — cheapest for long stays
Buy a physical SIM in-country and you'll usually get the cheapest data and a local number for calls, deliveries, and app verifications. The costs are practical: finding a shop, showing your passport, and sometimes a language barrier. Past a few weeks in one place, those minor hassles pay off — which is why nomads often start a stay on an eSIM and switch to a local SIM once they've settled.
Roaming — easy but usually pricey
Roaming means using your home plan abroad with zero setup — it just works when you land. The problem is cost: unless your carrier includes cheap or free roaming where you're going, you'll pay several dollars a day or steep per-megabyte rates. It's fine as an emergency fallback or for a very short hop, but as a primary connection for a nomad it's the most expensive option. Most people keep roaming off and let an eSIM handle data.
Frequently asked questions
Almost always, yes. Roaming on your home plan can cost several dollars per day or high per-megabyte rates, while a travel eSIM gives you a local-priced data bundle that's typically a fraction of that. Unless your home carrier includes free or cheap roaming where you're going, an eSIM saves money on nearly every trip.
For long stays in one country. A local SIM bought in-country often has the cheapest data and usually includes a local phone number for calls, deliveries, and app verifications. The trade-offs are finding a shop, showing ID, and sometimes a language barrier — worth it past a few weeks in one place, less so for short hops.
An eSIM. You buy and install it before you fly, land with working data immediately, and never hunt for a SIM shop or swap tiny cards. For trips of a few days to a few weeks, or when you're moving between countries, the convenience usually outweighs the small premium over a local SIM.
Yes, on a dual-SIM phone. You keep your home SIM active to receive calls and texts on your usual number and set the eSIM as your data line for cheap local internet. This is the setup most nomads use — home number reachable, data handled locally — just keep an eye on any roaming charges on the home line.
