Networks & coverage in Mexico
Your Flylo eSIM connects to Mexico's leading mobile network, with speeds up to 5G where available:
- AT&T Mexico2G / 3G / 4G / 5G
Coverage is strong across cities, resort areas and the main highways; it thins in genuinely remote areas like the Chiapas interior, the Copper Canyon and the emptier stretches of Baja California.
Staying connected in Mexico
Mexico is one of the easier countries in the Americas to stay connected in. Your Flylo eSIM connects to AT&T Mexico, one of the country's main networks, reaching up to 5G where it is available. In the places most UK travellers head for — Mexico City, Cancún, Playa del Carmen, Tulum, Guadalajara, Monterrey, Oaxaca, Mérida and Puerto Vallarta — you will find reliable 4G/LTE almost everywhere, with 5G increasingly common across the larger cities and resort zones. Coverage follows people and roads: towns, tourist corridors and the main toll highways are well served, so navigating the Riviera Maya or driving the Yucatán is straightforward. Signal naturally thins in genuinely remote spots — deep in the Chiapas jungle, the Copper Canyon, stretches of the Baja peninsula between towns, and some archaeological sites set well away from the nearest village. If your trip includes long drives or off-grid days, download offline maps before you set off so you are covered through the gaps. Because the eSIM installs over the internet, set it up while you still have Wi-Fi — at home before you fly, or at the airport on arrival — then it activates once you land. It runs alongside your normal UK SIM, so you keep calls and texts on your home number while using Mexican data for everything else.
Setting up your Mexico eSIM
Install over Wi-Fi before you fly, then the eSIM activates when you arrive in Mexico. Switch Data Roaming on for the Flylo line — the connection is roaming-based, so leaving it off stops the data working.
How much data will you need?
As a rough guide, five days of maps, messaging and social media is around 3-5 GB. Estimate your trip with our data calculator →

FAQs about eSIMs for Mexico
Does a Flylo eSIM work in Mexico?
Yes. Mexico fully supports eSIM roaming, and your Flylo eSIM connects to AT&T Mexico for data across the country. You just need an eSIM-compatible phone and to install the eSIM before you travel.
What is the coverage like outside the cities?
4G/LTE reaches the vast majority of populated areas, towns and main highways, so most road trips and resort areas are well covered. In genuinely remote places — dense jungle, canyon country or empty desert stretches — signal can drop, so download offline maps for those legs.
Does the eSIM come with a phone number?
No. It is a data-only eSIM, so there is no Mexican phone number for regular calls or SMS. You will still have data for internet-based calls and messaging like WhatsApp, FaceTime and iMessage.
Can I share the data by hotspot or tethering?
Yes. You can turn on your phone's personal hotspot and share the connection with a laptop, tablet or a travelling companion's phone.
What happens when I have used a lot of data on an unlimited plan?
You can keep using data for the whole plan. On unlimited plans speeds may be eased back after a fair-use threshold, but you will not face overage charges or a hard cut-off.
Do I need to turn on Data Roaming?
Yes. The eSIM uses a roaming connection, so switch Data Roaming on for the Flylo line in your settings. Your home SIM can stay as it is — this setting only affects the Flylo eSIM.
Can I keep my normal UK SIM active?
Yes. The eSIM sits alongside your existing SIM, so you keep your UK number for calls and texts while using the Mexican data plan for internet. Just set the Flylo eSIM as your data line.
Which network does the eSIM use in Mexico?
It connects to AT&T Mexico, one of the country's main networks, reaching up to 5G where that is available and 4G/LTE elsewhere.
Are eSIMs available in Mexico?
Yes. Flylo eSIMs work across Mexico on the strongest local 4G/5G carriers, with automatic network fallover so you stay online in cities, airports, on trains, and in rural stretches.
What is the best eSIM for travelling in Mexico?
Flylo is one of the cheapest unlimited-data eSIMs for Mexico — typically well below Holafly's and Airalo's per-day prices on the routes we track, and you can check our live comparison on the page. Install in 60 seconds, no SIM swap, no roaming bill.
How much does an eSIM for Mexico cost?
Flylo Mexico eSIMs start at $2.22/day for unlimited data. Durations run from short-stay plans up to a month — pick the length that matches your trip. No overages, no per-MB billing, and the price you see is the price you pay at checkout.
How do I buy an eSIM for Mexico?
Pick a plan above (1 to 30 days, all unlimited), pay with card, Apple Pay, Google Pay or PayPal, and the eSIM arrives by email in under a minute. No account hoops, no app forced on you.
How do I activate an eSIM in Mexico instantly?
Install the eSIM before you fly — it takes 60 seconds on a modern iPhone or Android. The eSIM activates the moment your phone connects to a tower in Mexico, typically as you taxi off the runway.
Does Flylo eSIM in Mexico support 5G?
Yes — Flylo plans run at full 5G speeds in any region of Mexico where the local carrier supports it, and 4G LTE everywhere else. Unlimited plans include a generous daily full-speed allowance; beyond it, speeds may be reduced until the allowance refreshes — your data never cuts off.
