Buying a SIM card at Miami International Airport (MIA)

One counter, and a short line

Our data names a single SIM seller at Miami International: a T-Mobile kiosk in the international arrivals area. The queue there runs 8 to 10 minutes, which is the shortest wait of any major US airport we hold figures for — comfortably under JFK's evening bank and shorter than LAX or O'Hare.

That is the whole retail picture we can vouch for. We hold no concourse-level detail, no second carrier counter, no electronics store, no vending machine, and no opening hours. If you land overnight, or arrive on a domestic connection well away from the international arrivals hall, we cannot tell you what will be open or how far you would have to walk.

Spanish at the counter

Miami's carrier stores across the city have Spanish-speaking staff, and the airport kiosks typically do too. For arrivals from Latin America that removes the usual friction of a technical purchase in a second language — plan sizes, validity periods and hotspot rules are exactly the things that get lost in translation at a counter. It is a real advantage of buying here rather than online, where support is mostly in-app and in English.

No ID, about $20, and the online prices

The United States asks for no identification to activate a prepaid SIM. No passport, no driving licence, no address. That applies at MIA as everywhere else in the country: pay and go. Our data puts a typical US airport SIM at around $20.

Here is what a complete US data package costs online, every row read from the seller's own site on 13 August 2026:

Do not stop reading at the small plans. The 50GB package at $42 with 30 days of validity is $0.84 a gigabyte, the cheapest rate anywhere in the US data — cheaper per gigabyte than the 20GB, and about a quarter of the rate on the 1GB. For a week in Florida on a hire car with mapping running, the arithmetic points up the ladder, not down it.

Airalo runs two named tiers in the United States, Change and Change+; the rows above are Change. Change+ costs more at each size and we do not hold what the extra buys. Our eSIM Go rows are prices nobody can pay, and our eSIMCard rows have been withdrawn. Nomad's US prices were read at source on 17 August 2026 and are verified.

Does the short queue change the answer?

Partly, and it is worth being straight about it. A lot of airport SIM advice is really queue advice, and at Miami the queue is close to a non-issue. Eight minutes at a counter after a flight from Bogotá or São Paulo is not a hardship, and if your phone cannot take an eSIM — check the compatible phones list before you fly — MIA is one of the easier places in the country to solve the problem on arrival.

What does not change is the money and the certainty. Around $20 at the kiosk is roughly the price of a verified 10GB month bought before departure, and buying online means you know the allowance, the validity and the price before you are standing in an arrivals hall. Buying at the counter means finding all that out at the counter.

Nobody publishes the network

None of the eSIM sellers we track for the United States — Saily, Airalo, eSIM Go, Nomad, eSIMCard — states which American network its plans use, so there is no way to shop on coverage. The kiosk is the exception only in the trivial sense that a T-Mobile counter sells T-Mobile service.

MIA connects directly to the Metrorail at Miami Airport station on the Orange Line, which is the one bit of Miami arrival logistics that works with no app and no data at all. Full US plan pricing, carriers and the local-SIM comparison are on the USA hub.
