How to Get Your eSIM
- Pick Your Mexico Data Plan
Choose from 1GB to 20GB options based on your trip length. A week exploring CDMX museums, markets, and day trips to Teotihuacan runs comfortably on 5-10GB. - Install at Home Before Your Flight
Scan the QR code over your home WiFi before heading to the airport. The profile loads in under 2 minutes and sits dormant until you activate it. - Board Your Flight to MEX
Keep airplane mode on during the flight. Your eSIM is ready and waiting — no action needed until you land at Benito Juárez. - Activate After Touchdown
Once the captain clears phone use and you taxi toward T1 or T2, switch off airplane mode and enable the eSIM line. Movistar connects within seconds. - Request Your Rideshare From the Gate Area
Open Uber or DiDi while still inside the terminal. By the time you clear customs and reach the designated pickup zone at Puerta 6 (T1) or Puerta 3 (T2), your driver is already waiting.
Traveler Tips
- Inter-terminal transfers on the Aerotrén require a same-day boarding pass — without one, budget 15-20 minutes for the landside taxi between T1 and T2.
- Uber and DiDi pickups at MEX are at designated zones: T1 upper level (Salidas) near Puerta 7-8, T2 second level near Puerta 3. Have the app open with your pin dropped before you exit.
- Currency exchange rates at the airport are noticeably worse than downtown — use your phone to find a Citibanamex or BBVA ATM in Roma or Condesa instead.
- Metrobús Línea 4 runs from both terminals to Bellas Artes and Buenavista but requires a rechargeable Tarjeta CDMX — buy and top up at the station kiosk using cash.
- Keep your home SIM active for incoming calls; use WhatsApp or FaceTime over your eSIM data for outgoing calls to avoid roaming charges.
- Download offline maps of CDMX before departure — Google Maps lets you cache specific neighborhoods, useful if you're navigating Centro Histórico's narrow streets.
Why You Need an eSIM at MEX
Mexico City International Airport — Aeropuerto Internacional Benito Juárez — funnels over 45 million passengers through two terminals annually, and the arrival flow demands data from the moment you clear immigration. The free airport WiFi requires registration that frustrates jet-lagged arrivals, and the SIM kiosk queue in Sala A adds 15-25 minutes to your exit time. An eSIM activated before departure bypasses both.
The Arrival Scramble
International arrivals clear customs through Sala A (T1) or the T2 international hall, where lines commonly stretch 30-60 minutes during mid-morning and late-evening peak banks. While you're waiting, you need data for three things: messaging your hotel transfer driver with your customs progress, checking the Uber app for surge pricing at your terminal, and pulling up your Airbnb check-in instructions. The authorized taxi kiosks (Sitio 300, Porto Taxi) take cash — but confirming the fixed-zone fare on your phone before approaching the counter keeps you from overpaying.
Terminal Navigation and Gate Updates
MEX's two terminals sit 3 km apart across the runways. The Aerotrén people mover connects them in 4-5 minutes, but only for passengers with a same-day boarding pass. Without one, you're stuck with the landside taxi option — and real-time traffic data (Google Maps, Waze) tells you whether that 3 km is a 10-minute ride or a 25-minute crawl. If you're connecting through MEX, the Aeroméxico app pushes gate-change alerts faster than the terminal boards update, and eSIMno plans for Mexico City International Airport keep that notification pipeline open.
Beyond the Terminal
Your MEX eSIM keeps working across all of Mexico. Navigate the Metrobús Línea 4 to the Zócalo (40-60 minutes, requires Tarjeta CDMX tap card), book a day trip to Teotihuacan through GetYourGuide, or call an Uber from your Polanco hotel to Mercado Roma. The same plan covers Oaxaca, Guadalajara, Cancún, and anywhere else your trip takes you — no second card, no top-up hassle.
Visiting Benito Juárez Airport
AICM operates 24 hours, though most retail and dining closes between 22:00 and 23:00. Overnight arrivals find Starbucks (T2) and Sanborns (T1) among the few outlets open past midnight. The Hilton Aeropuerto connects directly to T1 via walkway; the Hilton Garden Inn sits at T2 for early departures or long layovers.
Transit Options to the City
Metro Line 5 (yellow) serves T1 only — Terminal Aérea station is a 5-minute walk from domestic arrivals, but turnstiles and crowded cars make large luggage impractical. Metrobús Línea 4 runs from both terminals to the historic center; the airport fare is 30 MXN payable only by Tarjeta CDMX. Authorized taxi kiosks inside both terminals offer fixed-zone pricing — expect around 250-350 MXN to Roma/Condesa, 350-500 MXN to Polanco or Santa Fe. Uber and DiDi are legal; pickup zones are clearly marked at the upper (Salidas) level.
Connection Timing
Minimum connection times at MEX: 90 minutes same-terminal domestic, 2 hours T1↔T2 domestic, 3 hours for any international leg with a terminal change. Every international passenger clears Mexican immigration and customs on arrival — there is no sterile transit zone.
