Getting Online at Cancún International (CUN)

eSIM from 1,00 USD · 100 MB. Networks: AT&T (5G).

Cancún International (CUN): your options on arrival

The first thing you need on arrival: transport, maps and a message home. Having data before leaving the terminal saves time and stress.

Option 1: eSIM (activate before your flight)

1. Buy the eSIM on Wi-Fi at home or your hotel, and save the QR / activation link in your email.
2. Install the eSIM profile: iPhone → Settings → Mobile Data → Add Plan. Android → Settings → Network → Add eSIM.
3. On landing, enable the eSIM line as "Mobile Data". You're online in 1–3 minutes.

Option 2: Airport Wi-Fi

Free at most terminals, but often limited by time caps and slow during peak hours. Good only for basics (WhatsApp, email). Don't use it for banking apps or large downloads.

Option 3: Local SIM at the airport

May require passport and registration. Airport prices are typically 2–3× higher than in the city. There's often a queue — if you arrive late at night, shops may be closed.

What do you need in the first 30 minutes?

• Book transport: Uber, DiDi, InDriver needs ~10 MB to search and confirm a ride.
• Maps: routing to your hotel uses ~5 MB in Google Maps, Waze.
• Message home: a WhatsApp text + photo ≈ 1 MB.

Quick checklist: stay online without surprises

The make-or-break moment is often the first 30 minutes after landing: maps, transport, messages. Install your eSIM on Wi‑Fi before you travel and switch mobile data to the eSIM when you arrive. That way you're not dependent on airport Wi‑Fi and you avoid accidental roaming charges.

For typical use (maps + messaging + light social media), 1–3 GB per week is often enough. If you tether for a laptop, take video calls, or stream daily, aim for 10 GB+ or a plan with fair-use throttling instead of a hard cut-off.

• Networks: AT&T (5G)
• Offline maps: download the area in Google Maps, Waze while you're on hotel Wi‑Fi.
• On the move: Uber, DiDi, InDriver + WhatsApp work well on low data — video and app updates are usually the real data drains.
• Common weak spots: Jungle cenotes and Yucatán interior (Chichén Itzá area) · Mountain roads in Oaxaca and Chiapas highlands
• City context: Mexico City: Huge metro area; excellent 4G in tourist districts but drops in the metro tunnels. · Cancún: Hotel Zone has strong coverage; interior of the peninsula can be patchy.

Phone setup tip: keep your primary SIM active for calls/SMS (so 2FA codes can arrive), but turn off mobile data on that line. Set the eSIM as your data line — it prevents accidental roaming on the wrong SIM and keeps WhatsApp/banking flows more predictable.
