To get internet in Cancun you have three options: a Mexican prepaid SIM, a travel eSIM you set up before leaving, or roaming on your current plan. The SIM is easy to buy on arrival, at the airport, convenience stores or carrier shops, and your phone must be unlocked. The main carriers are Telcel, AT&T and Movistar, and Telcel has the widest coverage. Wi-Fi is easy to find in the city, and the hotel offers it for free.
How do you get a prepaid SIM in Cancun?
A prepaid SIM is the classic option and works well if you are staying several days. It is sold at convenience stores, at the carriers' own shops and at the airport, so you can sort it out the day you land. Check each carrier's current data packages and validity periods, because offers change often. Ask the shop to activate the line and test it before you leave, so you do not discover a problem once you are out on the street.
Before buying, make sure your phone is unlocked, meaning it is not tied to a single carrier back home. If you are not sure, ask your provider before you travel, because a locked phone will not accept a Mexican SIM. It also helps to know whether your phone supports two lines: that way you keep your usual number for verification messages and use the Mexican SIM for data.
Which carrier should you pick: Telcel, AT&T or Movistar?
The three carriers you will come across are Telcel, AT&T and Movistar. Telcel has the widest coverage in the country, which matters if you plan to leave Cancun by road, visit archaeological sites or reach small towns. AT&T and Movistar work in the city and may offer different packages. If your trip stays in Cancun, any of the three can be enough; if you plan to tour the peninsula, Telcel is the safest choice.
Compare the current packages in the shop itself: what differs is the data included and how many days it lasts. Ask how to top up if you run out of data, since it can usually be done at convenience stores and through the carrier's app. If your stay lasts several weeks, ask what options exist to renew the package without changing SIMs.
Is a travel eSIM better than roaming?
A travel eSIM is a digital SIM installed on your phone with no physical card, and you set it up before you leave. Its big advantage is that you arrive with data from the first minute, without hunting for a shop after your flight. You need an eSIM-compatible, unlocked phone. Compare Mexico coverage and data allowances before choosing, and install it on Wi-Fi before the trip so it is ready when you land.
Roaming depends on your plan. Many US and Canadian plans include Mexico, so you may already be covered; European plans usually do not, and the charges can come as a surprise. Check the terms with your provider before traveling and, if you are not convinced, switch off mobile data until you have another solution.
- Prepaid SIM: bought on arrival, requires an unlocked phone.
- Travel eSIM: set up before you leave, with data from the moment you land.
- Roaming: check your plan; US and Canadian plans often include Mexico, European ones usually do not.
Where does coverage get weak, and how to prepare?
In the city the signal is usually good, but it weakens on highways, at cenotes and in rural areas. If you are heading out on an excursion across the peninsula, to a cenote or to an archaeological site, do not count on having data the whole time. Before leaving, download offline maps of the area, save your bookings and tickets on the phone and share your location with someone you trust.

WhatsApp is the usual way to message businesses, hotels and guides in Mexico, so install it and keep your number up to date. To call home, use internet calling rather than traditional calls. Do not forget a charger and an adapter: we explain which plugs and voltage Mexico uses. On public Wi-Fi networks, avoid doing any banking.
Wi-Fi and places to work in downtown Cancun
If you stay downtown, getting connected is simple. The hotel offers free Wi-Fi, and at Onda Café, inside the hotel, you can work over specialty coffee. There are also a coworking space and a library for anyone who needs to concentrate. If you are traveling to work remotely, see our guide to Cancun for remote workers, with ideas for organizing your weeks in the city.
And if you have questions before arriving, you can write to the hotel through the channels on the contact page. Downtown is a good base for a connected trip: you are about 20 minutes by car from the airport, a few minutes on foot from the ADO bus terminal and about 15 minutes from the Hotel Zone. When you have your dates, book direct on the hotel website for the best available rate.
