Cancún eSIM guide: the airport, the Hotel Zone and day trips

Our Mexico plans connect to Telcel or AT&T México, with 5G where the network and your phone support it. They use an internet address outside Mexico, in Singapore, so a few Mexican sites may treat you as abroad.

Mexico's telecom regulator, the CRT, publishes each operator's own coverage maps by state. For Quintana Roo they show 4G reaching 95.95% of the population on Telcel and 94.70% on AT&T, and 5G reaching 79.10% on Telcel and 79.15% on AT&T, the second-highest state share for both. (source)

Cancún airport handled 1,607,088 passengers in September 2026 and 20,882,658 from January to September, 13,779,382 of them international, according to ASUR, the company that runs it. (source)

ASUR's own services directory for Cancún lists banks, currency exchange, baggage wrapping, tourist information and TELMEX landline service in Terminals 2, 3 and 4. It lists no mobile carrier store and no SIM seller. Some of the contact details on that page look like placeholders, so the directory may be out of date. (source)

The shop directory lists MOBO, a phone accessories store, in Terminal 2. The page does not say it sells SIM cards. (source)

ASUR publishes no Wi-Fi terms on its Cancún pages. An unofficial airport information site says the free network is CUN Wi-Fi, run by Prodigy Mobile, with a 60-minute limit on sponsored connections. (source)

The same unofficial site says Terminal 2 handles domestic and international flights, Terminals 3 and 4 international flights, and a free shuttle links the terminals with waits of up to 20 minutes. (source)

Telcel's April 2026 store directory for Quintana Roo lists six customer service centers in Cancún: Cancún Mall (11:00 to 21:00), Cancún I Crucero on Av. Tulum (9:00 to 18:00), Cancún III Chichén on Av. Chichén Itzá (9:00 to 18:00), Cancún IV Gran Plaza on Av. Nichupté (10:00 to 21:00), Cancún V Malecón at Las Américas on Av. Bonampak (11:00 to 21:00), and Cancún VI Express Huayacán (9:00 to 19:00), all open daily. (source)

All six are in the city's downtown districts. None is at the airport, and none has an address on Blvd. Kukulcán, the Hotel Zone road, so staying in the Hotel Zone means a taxi ride to buy a SIM. (source)

On October 14, 2026, Telcel's package catalog listed prepaid Amigo Sin Límite packages from MXN 50 for 7 days with 500 MB, up to MXN 500 for 30 days with 8 GB, bought by text message. (source)

A Mexican SIM bought as a visitor must be registered with your passport under Mexico's 2026 phone registry. Roaming on your home line, or on a foreign eSIM like ours, needs no registration today. (source)

Uber says its app works in Cancún at any hour, with UberX, UberXL, taxis and rides reserved up to 30 days ahead. Its airport page lists Taxi, UberX and Reserve, and warns that early or late flights may mean longer waits for a driver. (sources 1, 2)

Xataka México reported that from July 30, 2025 Uber offers reserved taxi-type rides inside Cancún airport with a local company, Flex Eco Taxi, booked up to 30 days ahead with your flight number, and that private cars are not part of it. (source)

The Tren Maya restarted its Cancún to Playa del Carmen trains on August 15, 2026 from Estación Cancún Aeropuerto, with departures at 06:45 and 10:30, a trip of about 49 minutes and a stop at Puerto Morelos. A connecting service, Tren Maya Conecta, links the stations with the airport and the hotel zones. (source)

Quintana Roo's tourism ministry and GigNet opened free public Wi-Fi at Playa Delfines and Kilómetro Cero in the Hotel Zone in October 2023. The Playa Delfines module covers 36,000 square meters and serves more than 2,500 devices a day, according to Riviera Maya News. (source)

Ultramar runs ferries to Isla Mujeres from three Cancún departure points: its Puerto Juárez terminal on Av. López Portillo, Playa Tortugas at km 6.5 of Blvd. Kukulcán, and Playa Caracol at km 9.5. (source)

Ultramar sends tickets by email, says they are non-refundable and valid for six months on the route bought, and asks you to arrive 30 minutes before departure. Its Puerto Juárez terminal lists internet service among its amenities. (sources 1, 2)

Chichén Itzá is in Yucatán state, where the operators' maps show 4G reaching 96.41% of people on Telcel and 92.85% on AT&T, but 5G only 46.59% and 40.08%. Expect 4G on the way there. (source)

INAH, which runs Mexico's archaeological sites, has said phones are not banned there and there is no charge for bringing one into Chichén Itzá. A MXN 60 fee applies only to filming for commercial purposes. (source)
