Is resort Wi-Fi enough in Cancún?
At the hotel, often yes. The eSIM is for everything else: finding your transfer driver at the airport, maps on day trips, and messages when you are away from the resort.

Before you buy: straight answers
Will my UK network charge me in Mexico?
Only if you use it. Before you land, turn data roaming off for your UK SIM, so it can’t start a daily charge, and use the eSIM for data. You can still receive calls and texts.
How much data do I need for a week in Mexico?
About 3 to 5 GB covers maps, messaging and social media for a week. If you plan to stream or share data with a laptop, choose a bigger plan.
What your trip to Mexico costs
Set your trip length and how you use your phone. eSIM bars are data-only plans that cover the whole trip; UK network bars use your UK allowance and include calls and texts. EE and Vodafone don’t publish a price for Mexico that we can check, so they aren’t charted.

See day passesHow we choose these plans
For each trip we pick the current plan that costs the least while lasting the whole trip and gives about 0.3 to 0.7 GB a day, enough for maps, messages and social media. A plan may last longer than the trip. Everyone uses data differently, so check your phone’s recent data use. “Best value” only appears when that plan also costs the least per GB of all the plans that fit.
Arriving in Mexico
- CUN Cancún
- MEX Mexico City
- PVR Puerto Vallarta
- SJD Los Cabos
- GDL Guadalajara
Most UK flights to Mexico land at Cancún (CUN). Transfers to the Riviera Maya take up to two hours, so having data on arrival helps you find your driver.
Signal where people go
- Cancún and the Hotel Zone
- Strong signal along the Hotel Zone and in town.
- Playa del Carmen and Tulum
- Good in town. Some beach clubs and cenotes are out of range.
- Mexico City
- Strong across the city, including most Metro stations.
- Chichén Itzá and the Yucatán
- Coverage thins between towns. Save offline maps before a road trip.

Your UK network in Mexico
Mexico is outside the EU, so Europe roaming deals on UK plans don’t cover it. What each network publishes for Mexico, and a week of it:
| Network | What it charges | 7 days | Compare |
|---|---|---|---|
 EE | Varies by plan EE doesn’t publish one price for every country: it prices roaming by destination, plan and start date. Check EE’s roaming tool for Mexico. | No published price | EE roaming |
| O2 | O2 Travel £7 a day with the O2 Travel Bolt On: unlimited calls, texts and data, at up to 2 Mbps. | £49.00£7 a day × 7 | O2 in Mexico vs eSIM |
| Vodafone | Global Roam zone Mexico is in Vodafone’s Global Roam zone. It’s included on Xtra Global Roam plans; on other plans a daily fee applies, which Vodafone shows in its roaming charge checker. | No published price | Vodafone roaming |

Know before you go
- All-inclusive Wi-Fi can be slow at busy times and often stops at the hotel gate. An eSIM keeps maps, ride apps and messages working on excursions.
- Your UK SIM can join a Mexican network in the background and charge you. Turn data roaming off for it and use the eSIM for data.
- Mexico is outside the EU, so Europe roaming deals on UK plans don’t cover it. Check your network’s Mexico rate before you fly.
Crossing a border from Mexico?
A Mexico plan covers Mexico only. This is what your UK network charges next door:
| Going on to | O2 | Three | Vodafone | eSIM |
|---|---|---|---|---|
| The USAtrips across the border into the USA | £7 a day | £8 a day (Go Roam Around the World) | Global Roam zone | The USA plans |
| Belizeday trips from Chetumal into Belize | Standard rates | Standard rates | Check Vodafone | Belize plans |
Set it up before you fly
- Check your phone is unlocked and supports eSIM on our compatibility page.
- Install the plan at home on Wi-Fi with our iPhone or Android guide.
- When you land at Cancún, switch mobile data to the eSIM and turn on data roaming for it only.

Does a Mexico eSIM work in Tulum and the cenotes?

Does a Mexico eSIM work in the USA?
A Mexico-only plan covers Mexico. For a trip that crosses into the USA, add a USA plan or check the coverage list of a North America plan.
Is a travel eSIM cheaper than roaming in Mexico?
For a week with about 0.7 GB a day, the Graba SIM 5GB, 30 days plan costs £27.75, less than each published UK network option for Mexico (the lowest is Three at £42.00). UK network prices include calls and texts; the eSIM is data only.
