FairSIM eSIM for Mexico
In Mexico, WhatsApp is the phone line. Hotels, tour guides, taxi drivers and the cenote you want to visit all answer on it, and DiDi or Uber will not find you at the kerb without data. Resort Wi-Fi rarely reaches the beach.
A FairSIM eSIM for Mexico connects to Telcel, the network that wins every coverage award in the country, to AT&T México or to Movistar, at the wholesale rate. And since January 2026 every Mexican SIM must be registered to a passport or unregistered lines are cut off. A foreign travel eSIM roams instead of registering, so none of that paperwork applies.

How FairSIM works
Three steps between you and the internet abroad. Nothing to pick up at the airport.
Pick a destination and a plan
Choose the country or region and the data you need. The price you see is the price you pay.
Tap install
On iPhone (iOS 17.4+) the eSIM installs in one tap, no QR code. Do it at home while you still have Wi-Fi.
Land and connect
Turn on data roaming for the FairSIM line when you arrive. Your plan starts when it first connects.
Connectivity tips for Mexico
Coverage is Telcel-first. If you leave the big cities, pick a plan on Telcel; AT&T México is noticeably weaker in the Yucatán jungle, Chiapas and the Oaxaca coast.
Holbox has no reliable signal on any network, and Bacalar and El Cuyo are patchy. Download offline maps and your hotel address before boarding the Chiquilá ferry.
WhatsApp is the national phone line. A data-only eSIM is enough to book tours, message hotels and even hail taxis.
Ride-hailing works in Mexico City, Guadalajara, Monterrey, Vallarta and Cabo. At Cancún airport take the ADO bus or an authorised taxi.
Quintana Roo is on UTC−5 while Mexico City is UTC−6, and nobody uses daylight saving. Keep automatic time zone on for flights and buses.
Hurricane season, June to November, can knock out coastal towers for hours. Keep offline copies of bookings and boarding passes.
Most travel eSIMs deliver 4G LTE in Mexico, which is plenty. Expect 20 to 50 Mbps in normal use.
Can you rely on free Wi-Fi?
Common in hotels, cafés, ADO buses and resorts. Mexico City holds the record for free public Wi-Fi with around 30,000 hotspots, including Metro stations and parks. Quality varies: good in city cafés, slow on islands and beaches. Avoid banking on open networks.
Local SIM card or eSIM in Mexico?
Telcel Amigo SIM kits cost MXN 29 to 149 at OXXO, Telcel stores and Walmart, with top-ups of roughly MXN 50 to 200 for 0.5 to 6 GB, usually with unlimited WhatsApp and Facebook. Cheap, but the packs favour social apps over the gigabytes you need for maps.
Since 9 January 2026 every Mexican SIM and eSIM must be registered with an ID, a passport for tourists, and unregistered lines are suspended from July 2026. Foreign travel eSIMs operate in roaming mode and are exempt from the registry. A FairSIM eSIM runs on the same Telcel network with no counter and no paperwork.
Mexico eSIM questions
Does eSIM work in Mexico?
Yes. Any unlocked eSIM phone connects to Telcel or AT&T México. FairSIM installs in one tap and activates when you land.
Which network is best in Mexico?
Telcel. It wins Opensignal's 2025 awards for coverage, reliability and speed. AT&T México is fine in cities but weaker in rural Yucatán and the south. Movistar is a third option in the big cities. The app shows the network for each plan.
Is there 5G in Mexico?
Telcel has 5G in more than 125 cities and AT&T in the major metros, but many travel eSIMs run on 4G LTE, which is plenty for maps, WhatsApp and video.
Can I use my eSIM as a hotspot?
Yes. Every FairSIM plan supports Personal Hotspot, with no separate cap. Useful for laptops when café Wi-Fi is slow.
Do I need to register my eSIM under Mexico's new SIM law?
No. The 2026 registry applies to Mexican SIMs and eSIMs. Foreign travel eSIMs roam on Telcel or AT&T and are exempt.
Can I call and use WhatsApp?
WhatsApp calls and messages work fully over data. There is no Mexican number, so keep your home SIM for SMS codes.
How much data for 7, 14 or 30 days?
Resort trip: 3, 6 and 12 GB. City and culture: 5, 10 and 20 GB. Remote work with hotspot: 10, 20 and 40 GB. Top up in the app at any time.
Local Telcel SIM or travel eSIM?
Telcel is cheap but needs a store, a physical SIM or in-store eSIM, and passport registration. A travel eSIM is set up before departure, needs no ID, and works on the same Telcel network.
What is an eSIM?
A SIM card built into your phone. Instead of a plastic chip, you download a profile. Every iPhone since the XS has one next to the physical SIM slot, so your home number stays put while FairSIM supplies the data.
Is my phone compatible?
FairSIM works with eSIM-compatible, carrier-unlocked iPhones: the XS, XR and everything newer, on iOS 17.4 or later for the one-tap install with no QR code. iPhones bought in mainland China do not support eSIM at all, even when unlocked. Not sure yours is unlocked? Check Settings, General, About, Carrier Lock, or ask your carrier. The full list is on the How it works page.
When should I install my eSIM?
Before you travel, while you still have Wi-Fi. Installing does not start your plan; the validity typically starts when the eSIM first connects to a network at your destination.
Do FairSIM eSIMs come with a phone number?
No. FairSIM eSIMs are data-only by design, which keeps costs low. For calls and texts, your physical SIM stays active so you keep your existing number, and WhatsApp, FaceTime and iMessage work over data.
