Getting online at Mexico City (MEX)
Mexico City’s airport is Latin America’s busiest; arrivals face heavy traffic into the city where ride-hailing and live maps are invaluable.
Most large airports, including Mexico City (MEX), 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 Mexico 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 Mexico City (MEX): 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.
Almost every phone sold in the last few years supports eSIM. If you're not sure, our eSIM compatibility checker confirms your model in a tap.
