# How Much Does a SIM Card Cost? > The card itself is usually free. What costs money is the plan attached to it — and the three ways to buy connectivity abroad differ enormously.

Carriers give them away with a plan, charge a token amount for a replacement, and would rather you had one than not. If you are being quoted a meaningful sum for a SIM alone, you are being quoted for the plan bundled with it. Which means the useful question is not what a SIM costs but what working data in another country costs. There are three ways to buy it and they differ by roughly an order of magnitude. ## The three routes Ranges rather than prices, because tariffs vary by market and change constantly — but the ordering is stable: - Your home carrier’s roaming, at a daily pass or a per-megabyte rate. Simplest, no setup, and consistently the most expensive per gigabyte. - A local prepaid SIM bought on arrival. Usually the cheapest per gigabyte, at the cost of queueing, showing ID in many countries, and losing your own number while it is in the tray. - A travel eSIM bought before you go. Close to local pricing, no queue, and — because [a recent iPhone runs two lines at once](https://support.apple.com/en-us/118227), as recent Android phones do — your home number keeps working alongside it. The gap between the first and the other two is the one that matters. It is routinely a factor of five or more, which is why the question is worth two minutes before a trip. ## When the local SIM genuinely wins It often does, and pretending otherwise would be dishonest: 1. Long stays. Over a few weeks, local prepaid pricing is hard to beat, and you may want a local number anyway. 2. Markets with unusually cheap domestic data, where a local SIM undercuts everything. 3. A phone that cannot take an eSIM — [no EID, no profile](https://esimradar.com/blog/eid-number) — where it is that or [a rented hotspot](https://esimradar.com/blog/pocket-wifi-vs-esim). > **Note:** Airport kiosks are the exception to the exception. They price for people who have just landed and have no alternative, and the same operator’s SIM is routinely cheaper in a city-centre shop or a supermarket. If you are buying locally, it is worth waiting until you are past arrivals. ![A busy airport terminal concourse with departures and arrivals signs overhead.](https://esimradar.com/blog-images/sim-card-costs/airport-kiosk-1730814-1280.webp) *The one place a local SIM reliably loses. Kiosks here price for people who have just landed and have no alternative — the same operator is cheaper in town.* ## The costs that are not the sticker price A local SIM has real friction attached, and it is worth pricing your own time honestly: - Registration. Many countries require ID to activate a prepaid SIM, which turns a purchase into a queue and some paperwork. - Your own number goes quiet while the local card is in the tray, unless the phone takes two lines. - Unused credit, which almost never comes back. - Time on arrival, when it is the least available thing you have. ## What your home carrier is really charging for Roaming is not priced by cost. Your carrier pays the local operator wholesale and sets the retail figure themselves, which is why the same trip is free on one contract and expensive on another. UK government guidance makes the consequence explicit: since the UK left the EU, [surcharge-free roaming in Europe is no longer guaranteed](https://www.gov.uk/guidance/using-your-mobile-in-eu-and-eea-countries), and the statutory £45 ceiling on data used abroad lapsed with it — many providers kept that cap voluntarily, but it is no longer something you have by default. That is why [checking the protections you already have](https://esimradar.com/blog/roaming-charges), including a spend cap, is worth doing before you buy anything at all. Some travellers are covered without knowing: an EU-issued line travelling in the EU has [its domestic allowance included](https://esimradar.com/blog/free-data-roaming-europe) and should buy nothing. The rule [now reaches Iceland, Liechtenstein, Norway, Moldova and Ukraine too](https://europa.eu/youreurope/citizens/consumers/internet-telecoms/mobile-roaming-costs/index_en.htm), and still excludes Switzerland and the UK. ## Comparing the way that actually works Divide by the gigabytes. A daily pass looks small and a 10 GB plan looks large until you work out what each costs per GB over the length of your actual trip — which is the number we rank on.

The card itself is usually free or a token amount. Any meaningful price you are quoted is for the plan attached to it, not the plastic. ### Is a local SIM cheaper than a travel eSIM? Often slightly, especially on long stays — at the cost of queueing, ID registration in many countries, and losing your own number while it is in the tray. ### Should I buy a SIM at the airport? Rarely. Airport kiosks price for people with no alternative; the same operator is usually cheaper in a city shop or supermarket. ### Why is roaming so much more expensive than a local plan? Because it is priced by your carrier rather than by cost. They buy wholesale from the local operator and set the retail figure themselves. --- More guides: https://esimradar.com/md/blog.md Compare plans by destination: https://esimradar.com/md/destinations.md
