Why roaming is one of the last great rip-offs in travel
Roaming is what happens when your phone uses a foreign carrier's network instead of your own. Your home carrier does not own towers in Tokyo or Lisbon, so when you land, it strikes a wholesale deal with a local network to carry your data — then charges you a retail markup that can be hundreds of times the underlying cost. That gap between what the data costs and what you pay is the business model. It is not an accident, and it is not a fee for a premium service. It is the product.
For years travelers had no real alternative. You either paid the daily pass, bought a local SIM by fumbling through a foreign electronics store, or switched your phone off and went dark. None of those is good. Daily passes feel reasonable until you do the math on a two-week trip with a partner and two phones. Local SIMs mean queueing at the airport, handing over your passport, and hoping the staff speak your language. Going dark means no maps, no translation, no ride-hailing — the exact tools that make modern travel safe and easy.
The eSIM changed the equation overnight
An eSIM is a SIM card built into your phone as software. Instead of a physical chip, you download a profile — a little file that tells your phone to connect to a specific carrier's network. Providers like Airalo, Holafly, Saily, and Nomad buy data in bulk directly from local networks and resell it to you at a fair price, with no roaming middleman taking a cut. You install the plan from your sofa days before the trip, and it activates the moment you arrive.
The savings are not marginal. A gigabyte of data that would cost $200+ in roaming charges in some countries costs $4.50 on an eSIM. That is the same data, on the same towers, routed without the markup. Once you have done it once, paying a carrier's roaming rate again feels faintly absurd — like paying airport prices for water when there is a fountain right there.
