Getting online
Free with no time limit, across the terminals. You do not have to buy anything or register a room number to use it.
- Open your phone's Wi-Fi settings Look for the airport's public network. Ignore anything with a similar-looking name and no captive portal.
- Accept the terms page A page opens automatically on most phones. If it does not, open a browser and visit any plain http:// site to force it.
- If it does not connect Turn Wi-Fi off and on, or forget the network and rejoin. Captive portals fail more often than the network itself.
Public Wi-Fi is public. It is fine for maps, messaging and checking a flight. Avoid banking, and if you must, use your mobile data instead. This is not specific to Cancun — it applies to every airport network in the world.
Where to actually charge
Sockets exist in every terminal, but the useful ones are not always where you first look.
- Gate areas have the most, usually along the walls and between seat blocks. The ones nearest the gate go first.
- Restaurants and cafés are the reliable option: buy a coffee and you get a table with power, which is worth more than the coffee.
- Lounges have power at most seats. Day passes and what they cost.
- Bring your own adapter. Mexico uses the same plug as the United States, type A and B, 127 V. Travellers from Europe and the UK need an adapter.
Mobile data instead
If you are here for a week and rely on your phone, a local eSIM is usually cheaper than roaming and works the moment you land. Buy and install it before you fly — activating one needs an internet connection, which is exactly what you do not have while walking through the terminal.
Coverage along the Cancun–Tulum corridor is good. It thins out at cenotes and on the smaller islands, which is worth knowing if you plan to rely on a map.
