Getting mobile data in Miami

The city is easy. Your home carrier is the expensive part

Miami is the main entry point to the United States for millions of Latin American travellers each year, and that changes what this page is about. For a visitor arriving from São Paulo, Bogotá or Buenos Aires, the meaningful comparison is not between one eSIM and another — the spread there is a few dollars. It is between buying anything at all and simply leaving your home SIM switched on.

US roaming is priced for business travellers, and rates charged by Latin American carriers for it are generally steep. Look up your own daily rate before you fly and put it next to $3.99, which is what a verified 1GB eSIM for seven days costs. For most people arriving in Miami that single comparison settles the question in under a minute, and it is worth doing even if you end up deciding to roam.

Signal is not something you need to think about

Coverage across Miami Beach, South Beach, Wynwood, Brickell, downtown, Coral Gables and the rest of the tourist circuit is excellent, with 5G from all the major carriers across the urban core. There is no Miami equivalent of a hill problem or a tunnel problem.

Miami International sits inside the city rather than an hour outside it, so there is no long transit ordeal on arrival — you can be in the hotel district in about 20 minutes. That removes the usual argument for having data live the second you land, though it does not remove the argument for having it before you reach the taxi rank.

The Keys are the only place it thins out

Miami Beach itself is fully covered. If you drive south, US-1 down to Key West has good signal along most of its length, with gaps in the more remote stretches of the middle Keys. It is a long, thin road with water on both sides and not much between the towns. Download the route before you leave the mainland and you will not notice the gaps.

A physical SIM is genuinely easier in Miami

The United States asks for no ID to sell you a prepaid SIM and activation is instant, which makes buying one shopping rather than admin anywhere in the country. Miami adds one thing on top: it is a bilingual city, and the carrier stores here have Spanish-speaking staff as a matter of course. If you are arriving from Latin America and would rather sort this out face to face than in an app, Miami is one of the least frustrating places in the US to do it.

Budget around $20 at an airport counter; retail stores in the city are cheaper. The reason to bother is a US phone number — for a rental desk, a restaurant confirming a booking, or a driver who needs to reach you.

What to buy

Prices marked verified were read from the provider's own site on 13 August 2026; the rest are indicative. Airalo sells the US as two named tiers, Change and Change+, at every size. The Change prices are shown below and we cannot say what the more expensive tier buys.

That row used to name eSIM Go at $17, and then eSIMCard. eSIM Go sells wholesale to resellers and publishes no consumer price — checked on esim-go.com on 18 August 2026, where there is no basket, no checkout and no per-country page — so its rows cannot be bought or ever verified. See our eSIM Go page. eSIMCard is a working storefront, but its prices have been withdrawn too: we read its own pages on 18 August 2026 and the figures we held were not the ones it charges. See our eSIMCard page.

A driving trip runs through data faster than a city break, because maps run for hours at a stretch. For Miami alone, 3GB to 5GB covers a week comfortably.

None of the providers we track for the United States publishes which American network its plans roam onto, so there is no carrier-based reason to prefer one over another here. Choose on price and size. The country-wide comparison, including the 50GB tier that sits at the cheapest cost per gigabyte we hold, is on our United States hub.
