Miami has no SIM shops in the international arrivals hall — you have to go up to the departures level for the Communitel and currency-exchange counters, or hunt kiosks in Terminals D/E, and prices run high (a basic prepaid SIM starts around US$37). A US eSIM installed before you fly means you walk straight past all of that, online.

MIA is an awkward airport for an arrival SIM: there are no SIM shops in the international arrivals hall itself — the two main sellers (a Communitel store and a currency-exchange counter) are one floor up on the departures level, with electronics kiosks around Terminals D and E carrying AT&T, T-Mobile and prepaid brands like H2O and Lycamobile. Prices skew high, with basic tourist SIMs from around US$37.

Getting online at Miami (MIA)
Miami is the gateway between the US, Latin America and the Caribbean and a major cruise-embarkation hub — many arrivals head straight to a port or onward flight.
Most large airports, including Miami (MIA), offer free terminal Wi-Fi — but that signal ends the moment you step outside to the taxi rank or train, which is exactly when you need maps, ride-hailing and messaging most. Buying a SIM at the counter means queueing after a long flight, showing your passport for registration, choosing from a short menu of tourist bundles, and swapping out your physical SIM so your home number goes offline. None of that is terrible — but all of it is avoidable.
How to be online before you leave the jet bridge
- Before you fly: pick a United States eSIM above and buy it — you'll get a QR code by email in minutes.
- Install it on home Wi-Fi: scan the QR in your phone's cellular settings. Leave the line switched off for now; your home SIM stays your default.
- When you land at Miami (MIA): turn off airplane mode, enable the travel eSIM's data line, and turn on data roaming for that line. It connects to a local network automatically.
- Walk out connected: maps, ride-hailing and messaging all work before you reach the taxi rank — no kiosk, no queue, no passport photocopy.
