| Network | #AICM_FREE_WIFI |
| Time limit | 2-hour sessions, renewable by accepting the terms again |
| Login | Captive portal, accept the terms; no password and no personal details |
| Local number needed | No |
| Speed | A new Wi-Fi 7 network went live in June 2026 with 800 access points, so the launch spec is fast; traveler reports are still thin. |
| Coverage | Both terminals, from the public concourses to the last boarding lounges. The signal ends at the terminal doors, so none at the taxi or rideshare zones. |
Have data before the Wi-Fi question comes up
Airport Wi-Fi is fine for a message home and useless for the things you need on arrival: booking a ride, finding the hotel, checking in with the driver. An eSIM installed before you fly connects the moment your phone leaves airplane mode at MEX, on the local networks, with nothing to log in to. The plan only starts counting when it first connects in Mexico, so you can buy it weeks ahead.
Installs in about a minute. No app, no account. Works on your phone or a full refund.
SIM cards at MEX
Telcel store on the upper floor of Terminal 1 near Puerta 5 (about 9am-7pm), plus OXXO and 7-Eleven outlets in both terminals. A tourist SIM is roughly 150-300 MXN, 20-30% above city prices.
Arriving at MEX
Buy a prepaid taxi voucher at the Transporte Terrestre Autorizado counters inside arrivals; fares are fixed by zone. Since March 2026, Uber and DiDi pick up only at a marked zone about an 8-minute walk between Terminals 1 and 2.
