The official 911 CDMX earthquake-alert app requires a Mexican phone number, the Cancún taxi dispute affects which transport is safe to book, and phone-based virtual kidnapping scams mean your family should agree a plan with you before you leave. ### Mexico: quick facts | Fact | Mexico | | --- | --- | | Emergency number | 911 | | Main airports | Mexico City International Airport (MEX); Cancún International Airport (CUN); Guadalajara International Airport (GDL); Los Cabos International Airport (SJD) | | Plug types | Type A, B (127V) | | Currency | Mexican peso (MXN) | | Apps worth having | Uber, DiDi, WhatsApp, Google Maps, Google Translate | ### Earthquake alarms in Mexico City: SASMEX and the 911 CDMX app (Mexico · https://viasimo.com/destinations/mexico/#guide-earthquake-alarms-in-mexico-city-sasmex-and-the-911-cdmx-app) Mexico City has a public earthquake warning system, **SASMEX**, run by the CIRES research centre. Its sensors detect an earthquake and broadcast an alert, which sounds from more than 8,200 street loudspeakers across the city and is relayed by local broadcasters. Depending on where the quake starts, people in Mexico City can get up to about a minute's warning. The Metro also receives the alert and stops or holds trains. The system covers several other cities too, including Puebla, Oaxaca, Acapulco, Morelia, Guadalajara and Toluca. The UK Foreign Office points to the **911 CDMX** app, which sends earthquake warnings for Mexico City. However, it works with **Mexican phone numbers**, and this eSIM is data only with no local number, so don't rely on it. Instead, learn what the siren sounds like, follow AlertaSísmica SASMEX on X for updates, and when you check in, ask your hotel where its safe zones and exits are. Earthquakes can knock out power and phone networks. After a large tremor, send a short WhatsApp message home as soon as you can, before networks become congested. ### Airport taxis, ride-hailing and the Cancún taxi dispute (Mexico · https://viasimo.com/destinations/mexico/#guide-airport-taxis-ride-hailing-and-the-cancun-taxi-dispute) The UK Foreign Office advises using only **authorised prepaid airport taxis** when you arrive, and licensed sitio taxis from official ranks, or a taxi ordered by your hotel, when you're in town. Australian advice adds that ride-hailing apps are generally a safer option than taxis flagged down in the street, because unauthorised taxis are linked to express kidnappings, where victims are forced to withdraw cash from ATMs. Cancún is a special case. Licensed taxi drivers there have protested against Uber, blocking roads and even pulling tourists out of Uber cars. If you land at Cancún (CUN), the simplest option is a prepaid airport taxi or a shuttle booked in advance to Playa del Carmen or Tulum. Keep the booking confirmation as a screenshot on your phone. When you withdraw money, use ATMs inside shops or shopping centres during the day, and avoid taking out large amounts. Australian advice warns that gangs have targeted travellers after they changed money at airports, so keep your phone and wallet out of sight as you leave the terminal. ### Virtual kidnapping calls: agree a plan with family at home (Mexico · https://viasimo.com/destinations/mexico/#guide-virtual-kidnapping-calls-agree-a-plan-with-family-at-home) One crime in Mexico specifically targets your phone and your family. In a **virtual kidnapping**, criminals phone or message someone, pretend a relative or colleague has been kidnapped or arrested, and demand an urgent money transfer. They're more convincing if they've stolen or hacked the phone of the person they claim to be holding, so they can contact that person's friends and family directly. Before you travel, the UK and Australian governments recommend agreeing with family how you'll keep in touch and how money would be sent in a real emergency. Practical steps include: - Agree a code word that only you and your family know. - Tell them that any request to send money should be checked with you directly first. - Turn on a screen lock and two-factor authentication for WhatsApp and email. If you get a threatening call, hang up and contact the person who is supposedly in danger yourself. With your eSIM, you can usually reach them on WhatsApp within a few seconds. Avoid using public wifi and Bluetooth, which can expose your accounts. ### Hurricane season on the Caribbean and Pacific coasts (Mexico · https://viasimo.com/destinations/mexico/#guide-hurricane-season-on-the-caribbean-and-pacific-coasts) Mexico's hurricane season usually runs from **June to November** and affects both coasts: the Caribbean side from Cancún to Tulum and the Pacific resorts such as Puerto Vallarta, Acapulco and Los Cabos. Storms bring flooding, landslides and transport disruption, and flooding and strong winds can continue after a storm has passed. The UK Foreign Office recommends following updates from the **US National Hurricane Center** and the local authorities, and obeying any evacuation orders. Turn on push alerts in a weather app while you have a connection, so warnings reach you without you having to check. Save your tour operator's and airline's WhatsApp numbers too, as flight changes are often announced at short notice. Mobile networks and power can fail during a storm. When a hurricane is forecast, charge a power bank, download offline maps of where you are and your route to higher ground, and screenshot your hotel booking, flight details and insurance policy. Message home before the storm arrives to say where you'll be sheltering. ### Sources for the Mexico guide - [Mexico travel advice: safety and security (GOV.UK)](https://www.gov.uk/foreign-travel-advice/mexico/safety-and-security) - [Mexico travel advice (Smartraveller)](https://www.smartraveller.gov.au/destinations/americas/mexico) - [Mexican Seismic Alert System (Wikipedia)](https://en.wikipedia.org/wiki/Mexican_Seismic_Alert_System) - [Plug, socket and voltage by country (World Standards)](https://www.worldstandards.eu/electricity/plug-voltage-by-country/) ## Seven days in Mexico: Mexico City, Teotihuacán and Oaxaca 7-day itinerary · 7 days · Source: https://viasimo.com/destinations/mexico/#itinerary A culture-focused first week: four days in Mexico City for the Aztec centre, the anthropology museum, Teotihuacán and Coyoacán, then a short flight to Oaxaca for Monte Albán, craft villages and the Mitla valley. **When to go:** October to April is dry and mild in both cities, with Día de Muertos in late October and early November especially strong in Oaxaca; May is the hottest month and June to September brings afternoon storms. ### Day 1 in Mexico: Mexico City: the Zócalo and Templo Mayor - **Base:** Mexico City - **Getting there:** Mexico City airport to the Centro Histórico is about 30 to 60 minutes; use an authorised prepaid airport taxi or a ride-hailing app. - **Plan:** Start on the Zócalo with the Metropolitan Cathedral and the Palacio Nacional, where Diego Rivera's murals line the main staircase; bring your passport for entry. Walk to the Templo Mayor, the excavated heart of Aztec Tenochtitlan, and its museum. In the afternoon, follow Calle Madero to the Casa de los Azulejos and the Palacio de Bellas Artes, then view it from the terrace across the road at sunset. - **Mobile signal:** Telcel and AT&T 4G and 5G cover central Mexico City, and the Metro has signal in many stations. The 911 CDMX alert app needs a Mexican number, so learn the sound of the street earthquake sirens instead. ### Day 2 in Mexico: Chapultepec: the Museo Nacional de Antropología - **Base:** Mexico City - **Plan:** Spend the morning at the Museo Nacional de Antropología, focusing on the Mexica hall with the Sun Stone and the Maya and Oaxaca galleries. Walk through Chapultepec Park and climb to Chapultepec Castle for its murals and view down the Paseo de la Reforma. In the evening, walk the tree-lined streets of Roma and Condesa around Parque México. - **Mobile signal:** Strong 4G and 5G across Chapultepec, Roma and Condesa. The museum's courtyard has good coverage, though the interior galleries are weaker. ### Day 3 in Mexico: Teotihuacán - **Base:** Mexico City - **Getting there:** Teotihuacán is about 50 km north-east of the city, around 1 hour by bus from the Terminal del Norte or by tour or ride-hailing car. - **Plan:** Arrive at Teotihuacán, a UNESCO site, when it opens to beat the heat and crowds. Walk the Avenue of the Dead from the Ciudadela and the Temple of the Feathered Serpent to the Pyramid of the Sun and the Pyramid of the Moon; climbing rules change, so check on the day. Visit the site museum and the murals at the Palace of Quetzalpapálotl before heading back in the afternoon. - **Mobile signal:** 4G is generally good across the site on Telcel. Bring water and sunscreen; there is very little shade and phones overheat on the pyramids at midday. ### Day 4 in Mexico: Coyoacán and Xochimilco - **Base:** Mexico City - **Getting there:** Coyoacán is about 30 minutes from the centre by taxi; Xochimilco is around 30 to 45 minutes further south. - **Plan:** Visit the Museo Frida Kahlo, the Blue House in Coyoacán, with a timed ticket booked in advance, then walk to the plazas and the market in central Coyoacán. In the afternoon, head south to Xochimilco, part of the UNESCO site, and hire a trajinera boat through the canals and chinampas, the floating fields that survive from the Aztec era. Agree the time and route at the official embarcadero. - **Mobile signal:** Good 4G in Coyoacán. On the Xochimilco canals the signal is generally usable, though data slows when the boats are crowded at weekends. ### Day 5 in Mexico: Fly to Oaxaca: Santo Domingo and the markets - **Base:** Oaxaca - **Getting there:** Mexico City to Oaxaca is about a 1-hour 15-minute flight; buses take around 6 hours. Protests sometimes block roads to Oaxaca airport, so check local news and allow extra time. - **Plan:** Fly to Oaxaca and walk the UNESCO-listed historic centre. Visit the Templo de Santo Domingo de Guzmán, with its gilded interior, and the regional museum in the former convent next door. Book a guided visit to the Ethnobotanical Garden behind it. In the late afternoon, eat in the Mercado 20 de Noviembre and walk to the Zócalo for the evening. - **Mobile signal:** Telcel 4G across central Oaxaca. The thick stone walls of Santo Domingo weaken the signal indoors. ### Day 6 in Mexico: Monte Albán and the craft villages - **Base:** Oaxaca - **Getting there:** Monte Albán is about 20 to 30 minutes from central Oaxaca by shuttle bus or taxi; the craft villages are within 45 minutes. - **Plan:** Go up early to Monte Albán, the Zapotec capital on a flattened mountaintop above the valley, and walk the Gran Plaza, the ball court and the carved Danzantes stones. In the afternoon, visit San Bartolo Coyotepec, known for its black pottery, and San Martín Tilcajete or Arrazola, where families carve and paint alebrijes, the colourful wooden animals. - **Mobile signal:** 4G on the hilltop at Monte Albán is generally good. Signal in the craft villages is weaker and can drop to 3G. ### Day 7 in Mexico: Tule, Teotitlán, Mitla and Hierve el Agua - **Base:** Oaxaca - **Getting there:** This is a full day of about 150 km round trip from Oaxaca; Hierve el Agua is roughly 1 hour 30 minutes from the city by road. - **Plan:** Drive east through the Valley of Oaxaca. See the Árbol del Tule, a cypress with one of the widest trunks in the world, then visit a family workshop in Teotitlán del Valle to watch wool rugs being dyed and woven. Continue to Mitla for its geometric stone mosaics, and finish at Hierve el Agua, mineral springs that have formed white rock cascades. Access is run by local communities and sometimes closes, so check before you set out. - **Mobile signal:** 4G holds as far as Mitla, then becomes weak or absent on the mountain road to Hierve el Agua. Download your route and arrange a pick-up time before you lose signal. ### Staying connected on this Mexico route - Your eSIM uses Telcel and AT&T; the 911 CDMX earthquake app needs a Mexican number, so rely on the street sirens and SASMEX updates. - Agree a code word with family before you leave in case of a virtual kidnapping call or message. - Download an offline map of the Valley of Oaxaca, as coverage fades on the road to Hierve el Agua. - Use authorised airport taxis or ride-hailing apps, and save booking confirmations offline. ### Sources for the Mexico itinerary - [GOV.UK foreign travel advice: Mexico warnings and insurance](https://www.gov.uk/foreign-travel-advice/mexico/warnings-and-insurance) - [GOV.UK: Mexico safety and security](https://www.gov.uk/foreign-travel-advice/mexico/safety-and-security) - [UNESCO World Heritage: Historic Centre of Mexico City and Xochimilco](https://whc.unesco.org/en/list/412) - [UNESCO World Heritage: Pre-Hispanic City of Teotihuacan](https://whc.unesco.org/en/list/414) - [UNESCO World Heritage: Historic Centre of Oaxaca and Archaeological Site of Monte Albán](https://whc.unesco.org/en/list/415) - [Smartraveller: Mexico](https://www.smartraveller.gov.au/destinations/americas/mexico) ## About this eSIM Two networks carry mobile traffic in Mexico on this plan: Telcel and AT&T, both running 4G LTE and 5G where it has been rolled out. That is a dense field by any standard, and it is why a country the size of Mexico feels well connected in the places visitors actually go. The gaps are real, but they are predictable: canyons, highland backroads, desert stretches between towns, and anywhere underground. ### Getting online when you land Whichever airport you come through, the routine is the same. Install the profile at home over wifi, keep it turned off, and switch it on once you are at the gate. Give the phone a couple of minutes to attach; it may try more than one network before it settles, which is normal in a market with this many operators. Immigration and customs at the big airports can be slow, which is useful: by the time you reach the arrivals hall you should already be online and able to order a car or check which authorised taxi counter you want. Set the data plan as your default data line, and keep your home SIM in place for calls and bank codes, with its roaming switched off. One practical note for Mexico City: the airport sits inside the city rather than out beyond it, so you go straight from the terminal into traffic. Having live routing running before you get in a car genuinely changes how long that first journey takes. ### The networks you'll be on Telcel has the broadest reach into small towns and rural highways, and it is the network your phone most often ends up on outside the cities. AT&T is strong across the metropolitan areas and the northern corridor. You do not choose between these; the plan attaches automatically and can move between partners as you travel. If you are in a fringe area and the connection feels stuck, opening the manual network selection screen and picking a different available network sometimes helps, then switch back to automatic once you are moving again. ### Where coverage holds, and where it thins Solid: the whole Mexico City metropolitan area, Guadalajara, Monterrey, Puebla, Querétaro and the Bajío cities, and the resort corridors. Along the Riviera Maya you stay connected from Cancún down through Playa del Carmen to Tulum, and the toll highways linking major cities are generally well covered end to end. Weaker: the Copper Canyon in Chihuahua, where the railway drops into gorges for long stretches; the Chiapas highlands and the roads between San Cristóbal and the smaller villages; the interior of the Baja peninsula between towns; the Sierra Norte above Oaxaca; and the free roads, the libres, that wind through mountains where the toll road tunnels straight through. Two specific cases worth knowing. Cenotes are underground and you will have no signal inside them, so agree a meeting point before you climb down. And the archaeological sites vary: the approach roads and visitor areas at the big ones like Yucatán's Chichén Itzá are covered, but the more remote jungle sites are not. ### What you'll actually use data for here Ride-hailing is the big one. Apps operate across the major cities and are the way most visitors move around after dark; without data you are negotiating on the street instead. In beach towns, colectivo vans and shared shuttles are cheaper but need you to know the routes, which is another map job. Then translation, which matters more outside the resort towns than inside them, and menus, which in Mexico reward looking things up rather than guessing. Bus travel is the other constant: the long-distance coach network is excellent and the operators sell and scan tickets through their apps, so a working connection saves you a trip to a terminal counter. Beyond that: checking beach and jellyfish conditions on the Caribbean coast, watching for the sargassum reports in season, and uploading the volume of photos this country inevitably produces. If you are in Puerto Vallarta or another Pacific resort during hurricane season, weather alerts are worth having push notifications for rather than checking occasionally. ### Before you fly Check that the phone is unlocked and eSIM capable, and install the profile before you leave home. Download offline maps for each region you are visiting rather than the whole country; Mexico is large and the individual regions are far more manageable as files. Save your accommodation address as a screenshot in Spanish, since a driver reading it is faster than a driver listening to you pronounce it. If you are driving, note which of your routes are toll roads and which are not, and expect the free alternatives to cost you signal as well as time. Keep a power bank in the day bag; long transfers between cities are common and seat power on buses is inconsistent. Finally, keep your home line's data roaming off, and make sure whoever might need to reach you knows to use a messaging app rather than a call, since that works over your data plan wherever you happen to be attached. ## Frequently asked questions ### Does an eSIM work in Mexico? Yes. Your Mexico eSIM connects automatically the moment you arrive, with no roaming fees and nothing to set up at the airport. The host networks it can use are AT&T, Telcel. Coverage runs on 4G LTE and 5G where the network has rolled it out, and falls back to 4G elsewhere. ### Do I get 5G in Mexico? Yes, where it has been deployed. 5G runs on AT&T, Telcel in Mexico, and your eSIM uses it automatically on a 5G-capable phone, dropping back to 4G LTE outside covered areas. No country is covered everywhere, so 5G availability varies by location. ### Will I get earthquake alerts on my phone in Mexico City? Not reliably with a travel eSIM. Mexico City's SASMEX system warns people through more than 8,200 street loudspeakers, giving up to about a minute's notice. The official 911 CDMX alert app works with Mexican phone numbers, which a data-only eSIM doesn't have. Learn the siren's sound, follow AlertaSísmica SASMEX on X, and ask your hotel about evacuation routes. ### Is it safe to use Uber from Cancún airport? It can lead to trouble. The UK Foreign Office reports that licensed taxi drivers in Cancún have protested against Uber, sometimes pulling tourists out of Uber cars and blocking roads. At the airport, official advice is to use authorised prepaid airport taxis. A shuttle to Playa del Carmen or Tulum booked in advance is another easy option. ### What is a virtual kidnapping scam in Mexico? Criminals call or message your family claiming you've been kidnapped or arrested and demand money, sometimes using a stolen or hacked phone to seem more convincing. Before travelling, agree a code word and a contact plan with your family. If anyone gets a threatening call, they should hang up and contact you directly, for example on WhatsApp. ### What is the emergency number in Mexico? Dial 911 for police, fire and medical emergencies anywhere in Mexico. Because the eSIM is data only, call from your home SIM, or ask your hotel to call. Save your embassy's number and your travel insurer's 24-hour line as well, and keep a screenshot of your hotel address in Spanish to read out. ### When is hurricane season in Mexico? Hurricane season generally runs from June to November, on both the Caribbean coast (Cancún, Riviera Maya) and the Pacific coast (Puerto Vallarta, Los Cabos, Acapulco). Follow the US National Hurricane Center and local authorities, enable push alerts in a weather app, and download offline maps before a storm, as power and mobile networks can go down. ### How much data do I need for 7 days in Mexico? For 7 days in Mexico, Viasimo sells 100 MB for $1.29, 500 MB for $2.29, 1 GB for $3.29, and unlimited data for $38.99. Our sizing recommendation, not a measurement: maps, messaging and the occasional lookup, about 1 GB a week; maps, social, photos and some browsing, about 3 to 7 GB a week. The data calculator on this site works it out from how you actually use your phone. ## Information and verification - **Prices and plans**: Every price and allowance on this page is read from the live catalog, not typed in.
