Does data work well in resort areas like Cancún and Tulum?

In the Cancún Hotel Zone and central Playa del Carmen, 4G/LTE connects smoothly. In Tulum, however, communications infrastructure is limited in some beach areas because of its eco-friendly policies. Most hotels and restaurants also provide Wi-Fi, so using your data sparingly is enough.

Is there any problem using the Uber app in Mexico City?

Mexico City has good Telcel 4G/LTE coverage, so you can use ride-hailing apps such as Uber and inDrive reliably. Your eSIM connects the moment you reach the Mexico City airport (AICM or the new AIFA airport), so you can call an Uber right away, which is convenient.

Does Mexico have different time zones in different regions?

Yes. Mexico is a large country, so different time zones apply depending on the region. Mexico City and Cancún are 14 to 15 hours behind Korea, and areas on the Pacific side differ by up to 16 hours. It pays to check the time zone of the cities you will visit before your trip.

Will I need a power adapter for Korean devices in Mexico?

Mexico uses type A/B sockets, and the voltage is 127V. This differs from Korea's 220V, so you may need a multi-adapter and a voltage converter. Most smartphone chargers work on 100–240V, so an adapter is all you need, but be sure to check appliances such as hair dryers before packing them.

Does the eSIM work in small inland towns like Oaxaca and Guanajuato?

Telcel is Mexico's largest carrier and provides basic 4G/LTE service even in small inland towns such as Oaxaca, Guanajuato and San Cristóbal. The signal can weaken if you go deep into mountainous areas or the rural outskirts, though, so we recommend saving offline maps beforehand.

Does eSIM work in Mexico?

Mexico supports eSIM, and plans start from ₩3,601. Install it with the QR code you receive after buying, then just turn on data roaming after you arrive and you are connected straight away. There is no need to swap your SIM.

Travel eSIM or carrier roaming: which is cheaper for a trip to Mexico?

For a short trip or light data use, a travel eSIM is usually cheaper. Unlimited roaming from Korean carriers costs about ₩11,000–₩15,000 a day, but with an eSIM you can buy just the days of data you need in advance. For a short trip for one or two people, an eSIM has a big advantage; for a family or very heavy data use, compare carrier unlimited roaming too.

Which carrier network does a Mexico eSIM use?

In Mexico it connects automatically to local carrier networks such as Telcel · AT&T Mexico · Movistar (Telefónica) (4G/LTE, 5G where supported). Population coverage is about 85%. It picks the network with the strongest signal automatically, so there is nothing to set up.

Can I keep using my Korean number while travelling in Mexico?

Yes. The eSIM works as a data-only second line, so your Korean SIM and number stay as they are. Use the Yeohaengyusim eSIM for data only, and keep receiving calls, texts and KakaoTalk on your Korean number.

Can I add to or extend my Mexico eSIM plan?

Yes. When you use up your data or the plan period ends, you can buy a new plan at any time. Keep using the eSIM profile you already installed; there is no need to install it again, so you carry on without interruption.

Can I use tethering (hotspot) in Mexico?

Yes. In Mexico you can share your eSIM data with other devices such as a laptop or tablet by tethering (hotspot). Shared data also comes out of your plan allowance, so if you tether a lot we recommend choosing a little more data.

Do I set up the eSIM before I leave or after I arrive?

We recommend installing it (registering the QR code) before you leave, while you have Wi-Fi. Data starts when you turn on data roaming after you arrive in Mexico. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

The endless emerald Caribbean Sea, ruins that bear the traces of the ancient Maya civilisation, and colourful street food — Mexico is still unfamiliar to travellers from Korea, but it is a captivating country you will want to return to once you have been. Whether you are relaxing on the white-sand beaches of Cancún, exploring the vibrant cultural spaces of Mexico City or strolling the colourful alleys of Guanajuato, there is no end to the scenes you will want to post on social media. Getting a SIM locally in Mexico, however, is more complicated than you might think. The queues at airport SIM shops are long, and with Spanish not easy to communicate in, choosing a plan can get confusing. Install your Yeohaengyusim eSIM before you depart and you can get online right after landing at Benito Juárez International Airport in Mexico City. Find your accommodation on Google Maps, call an Uber to get around and look up local restaurants in real time — enjoy Mexico more freely with Yeohaengyusim.

Why an eSIM really helps for travelling in Mexico

Mexico is a vast country with long distances between places. It is so big that even flying from Cancún to Mexico City takes over 2 hours, and if you hunt for a new SIM or search for Wi-Fi in every city, you waste precious travel time. You can buy a local SIM in Mexico at the airport or a convenience store, but English guidance is scarce, and if you do not speak Spanish it is often hard to pick exactly the plan you want. Mexico also relies heavily on Uber and Google Maps, so getting around without internet is very inconvenient. A stable data connection is essential in particular when travelling between the Cancún Hotel Zone and the centro, or heading out to outlying areas such as Tulum. Install your Yeohaengyusim eSIM on your smartphone in Korea before you depart and it connects to the Telcel network automatically as soon as you enter Mexico. There is no SIM card to swap and you keep your existing Korean number, so receiving urgent calls is no problem either. Thanks to the Telcel network, with coverage across 85% of Mexico, you can use data reliably not only in the cities but also in provincial areas such as the Yucatán Peninsula and Oaxaca.
