7 Best Prepaid SIM Cards in Mexico: Buying Guide

Mexico – known for its ancient temples, beaches & food.

Many Americans visit Mexico yearly. And that is understandable. The two countries share a long border.

Brits and Canadians love Mexico. Followed by various South American travelers.

But is it worth visiting Mexico? For sure.

Xcaret Park is stunning. So is Dos Ojos Cenote with caves and exciting swimming locations.

The many Mayan pyramids across the country, such as Chichém Itzá and Zona Arqueológica Palenque, need to be seen too.

Or you can enjoy the thrilling nightlife in Cancún and México City and recover from your hangover on the beach during the day.

As you can see, there is no need to be bored in Mexico.

While Mexico may not be the cheapest travel destination in the Americas, it is certainly cheaper than many other countries, like the ones in the Caribbean.

That is why you should save on costs wherever possible, like international roaming rates.

International roaming can be expensive. Using a local SIM card, like a Mexican one, allows you to enjoy local rates, which are significanyly lower than roaming rates.

Fortunately, SIM cards in Mexico are inexpensive.

You can get a Mexican SIM card for as low as 29 MXN (1.40 USD) to 200 MXN (9.50 USD) in Telcel, Movistar, AT&T & OXXO stores. Resellers, like 7-Eleven and Walmart, sell SIM cards too. You can also get SIM cards at select international airports, including México City-Benito Juárez International Airport.

Those prices are not too bad, right? And they often include a starter plan.

So you are not just paying almost 10 USD for a SIM card (unlike Canada and the United States, for example).

Speaking of those countries, you may be thinking: but I can roam for free in Mexico with an American/Canadian SIM card! Why do I need a Mexican one?

Well, you probably can! Most American and Canadian mobile network operators allow for free roaming in North America.

The issue, however, is that your roaming speeds are often annoyingly slow.

While mobile data speeds in Mexico are not as high as in Canada and the United States, the network quality you endure while roaming in Mexico will be significantly worse than if you used a Mexican SIM card.

So yeah, get a Mexican SIM card – you will thank yourself later.

In this guide, I will tell you everything you need to know about buying a SIM card in Mexico. Let's do this.

Can You Buy a SIM Card in Mexico?

Anyone living in or visiting Mexico can buy a Mexican SIM card from the mobile network operators (Telcel, Movistar & AT&T) or the Mobile Virtual Network Operators (MVNOs – Oui Móvil, OXXO CEL, Unefon & weex) in their stores or from resellers (like convenience stores) without any restrictions.

You do need a phone that supports the frequencies used in the country (preferably all of them to have the most optimal experience while in Mexico).

Furthermore, you need to have a SIM-lock-free device.

Where Can You Buy a SIM Card in Mexico?

You can get a Mexican SIM card in Telcel, Movistar, AT&T & OXXO stores. Resellers, including convenience stores, grocery stores & electronic shops, sell SIM cards too. Select international airports, including México City-Benito Juárez International Airport, also have SIM cards.

You can buy a SIM card in the following airports:

  • Bahías – Bahías de Huatulco International Airport (OXXO store just outside the airport)
  • Guadalajara – Miguel Hidalgo y Costilla Guadalajara International Airport (OXXO store just outside the airport)
  • México City – México City-Benito Juárez International Airport

You can expect to pay the following for Mexican SIM cards:

  • Telcel: 79 MXN
  • Movistar México: 50 MXN & 60 MXN
  • AT&T Unidos México: 150 MXN & 200 MXN
  • Oui Móvil: free, but top-up or plan purchase required
  • OXXO CEL: 29 MXN, but a 50 MXN top-up is also required
  • Unefon: 50 MXN, 100 MXN & 150 MXN
  • weex: 50 MXN

Can You Use Your Phone in Mexico?

Mexico uses GSM technology for mobile communications primarily. CDMA phones will not work in Mexico. However, almost all phones use GSM anyway.

You also need to be aware of the ITU regions to determine whether your phone will work in other parts of the world.

Although there are three ITU regions, you only need to know these two terms: American Frequencies and European Frequencies.

Mexico uses American Frequencies, which are used in the Americas (North-, Central, and South America + the Caribbean – ITU Region 2).

Phones sold in the Americas typically have no issues when using their phone in other ITU Region 2 countries.

In Africa, Asia (including the Middle East), Europe, and Oceania (ITU Regions 1 & 3), they typically use European Frequencies, meaning phones bought in those regions can be used in countries using European Frequencies without issues.

ITU Regions Map
By Maximilian Dörrbecker (Chumwa) – Own work, using this file by Denelson83, CC BY-SA 2.5

If you purchased your phone in the Americas (ITU Region 2), you should not experience any issues with using your phone in Mexico.

If you bought your phone in Africa, Asia, Europe, or Oceania (ITU regions 1 & 3) and have a low/medium-end device without Tri-Band or Quad-Band support, then there is a possibility you cannot use your phone when in Mexico or can only use slower networks (3G or 2G).

If you have a medium/high-end device with Tri-Band or Quad-Band support, you can use your phone in Mexico (to some extent) – also on 4G/LTE.

Mobile Operators, Networks & Frequencies in Mexico

Mexico has three mobile network operators and four Mobile Virtual Network Operators (MVNOs) easily accessible to travelers offering prepaid services:

  • Telcel
  • Movistar México
  • AT&T Unidos México
  • Oui Móvil (Telcel MVNO)
  • OXXO CEL (FreedomPop México/Telcel MVNO)
  • Unefon (AT&T Unidos México sub-brand)
  • weex (Movistar México MVNO)

The following frequencies are used in Mexico:

  • 2G: 850 MHz & 1900 MHz
  • 3G: 850 MHz & 1900 MHz
  • 4G/LTE: 850 MHz (Band 5), 1700 MHz (Band 4 & Band 66), 1900 MHz & 2600 MHz (Band 7 & Band 38)

You can learn more about frequencies in the video below.

To check whether your phone will work in Mexico, check out this page by Will My Phone Work (may be outdated or inaccurate at times).

Again, make sure your phone is unlocked. Otherwise, you will not be able to use any SIM card except the one from your home operator (meaning you have to roam internationally or buy another unlocked phone that does support the frequencies listed above).

If you want to learn how international roaming works, this guide explains it in-depth. If you wonder why it is often so expensive to roam, this article explains the hidden reason they do not want you to know.

A Note about Various MVNOs in Mexico

Coming soon.

5G NR in Mexico

5G NR is not available in Mexico as of 2022, and the Mexican government has not made any indications of when it will auction 5G licenses. However, it is expected to happen in (mid-/late-2022.

Best SIM Card in Mexico

If you want to buy the best SIM card in Mexico, I recommend going with Telcel. It is the fastest mobile operator in the country, and it has the best coverage. Consider Movistar & AT&T for slightly lower prices. But your network performance will be significantly worse than on Telcel.

SIM Card Registration in Mexico

SIM card registration, with the use of your personal information (such as your passport), is not required when buying a SIM card in Mexico (for now).

However, some stores will still ask you for your passport – especially at airports.

Moreover, the Mexican government plans on introducing a SIM card registration scheme.

The bill passed the Senate in April 2021, but it is unclear when it will be implemented.

In addition to your standard passport registration like most countries in the world, Mexico wants to join the short list of countries that require biometrics as well.

Furthermore, photographs, fingerprints, and a detailed record of where you live (in Mexico) will be registered too.

To make matters even worse, voice recording may also be required.

Currently, no other country requires a voice recording, so I wonder if that will actually be implemented.

Only Afghanistan, Bahrain, Bangladesh, Benin, China, Nigeria, Oman, Pakistan, Peru, Saudi Arabia, Tajikistan, Tanzania, Thailand, Uganda, the United Arab Emirates & Venezuela require biometric registration for SIM cards.

It is not the first time Mexico tried to implement a SIM card registration scheme.

The government tried it back in 2008. But it was rejected in 2011.

For now, bring your passport with you when you plan on purchasing a Mexican SIM card – just in case.

Currency in Mexico

500 Mexican Peso Bank Note
© Bank of Mexico/Banco de México (BdeM/Banxico)

Mexico uses the Mexico Peso with the symbol MXN (which will be used throughout this guide).

However, prices are often listed as just $, MX$, or Mex$. For example, 25 MXN = $/MX$/Mex$25.

For reference, below are some exchange rates between MXN and USD (US Dollars):

  • 1 MXN = 0.05 USD
  • 10 MXN = 0.50 USD
  • 100 MXN= 4.80 USD
  • 1000 MXN = 47.70 USD

For up-to-date MXN:USD exchange rates, search MXN to USD on Google, or replace USD with the currency you use.

If your credit/debit card charges you foreign exchange fees, get yourself a Wise Borderless Account and Debit Card.

Their fees are MUCH lower than banks, and credit card companies charge you (and Wise is transparent about their fees, unlike banks).

I have saved literal THOUSANDS of Euros, my main currency, when using Wise abroad when traveling compared to my debit and credit cards. Open a Wise account FREE!

Telcel

Telcel Mexico Logo

Telcel is the largest mobile operator in Mexico.

It has a market share of between 60% to 70% in the country.

Telcel is the local mobile brand by Américan Móvil, which is known as Claro in Central America and South America.

Telcel and Américan Móvil are owned by Carlos Slim Helú – the richest Mexican and the 25th richest person worldwide in 2021.

He was the richest man between 2010 and 2013.

While Telcel had, and somewhat still, has a monopoly (or significant market power), it got a considerable amount of customer service and quality of service complaints.

In recent years, competition has increased, especially when AT&T from the United States entered the market and Altan Redes – an enabler of the many MVNOs in Mexico.

This resulted in Telcel dropping its prices and improving its network.

To this day, it is still the best option in Mexico. It is, however, (slightly) more expensive than the competition.

Telcel uses the following frequencies:

  • 2G: 1900 MHz
  • 3G: 850 MHz & 1900 MHz
  • 4G/LTE: 850 MHz (Band 5), 1700 MHz (Band 4 & Band 66) & 2600 MHz (Band 7)

Movistar México

Movistar México, just Movistar, is the second-largest mobile operator in Mexico.

It used to be Telcel's only true competitor until AT&T USA bought Iusacell and Nextel México in 2015 and invested heavily in its network.

Movistar, as a brand, is active in Central America, South America & Spain.

Movistar uses the following frequencies:

  • 2G: 850 MHz & 1900 MHz
  • 3G: 850 MHz & 1900 MHz
  • 4G/LTE: 1700 MHz (Band 4) & 1900 MHz (Band 2)

Coverage – Movistar México

Movistar has extensive (3G) coverage throughout Mexico.

However, its 4G/LTE coverage is lacking – big time.

Even ALTÁN Redes, a Mobile Virtual Network Aggregator (MVNA) that started building its network not even five years ago, has far better 4G/LTE reception.

AT&T Unidos México

AT&T Logo
© AT&T

AT&T Unidos México, just AT&T, is the smallest full-service mobile operator in Mexico.

It is by the American AT&T, which entered the Mexican telecom market by buying up Iusacell and Nextel México in 2015.

Both mobile operators had limited coverage and could not compete with Movistar México and certainly not with Telcel.

With close to 100 million subscribers in its home market, AT&T decided to export its expertise across the border.

While it still has a long way to catch up with Movistar México with customer numbers, AT&T does have (way) better 4G/LTE coverage.

AT&T uses the following frequencies:

  • 2G: N/A – shut down in 2017
  • 3G: 850 MHz & 1900 MHz
  • 4G/LTE: 1700 MHz (Band 4), 1900 MHz (Band 2) & 2600 MHz (Band 7 & Band 38)

This is what you will learn about AT&T:

* Coverage

* Topping Up Options & Methods + Balance Check
* Plans & Packages
* APN/Internet Settings

Coverage – AT&T Unidos México

AT&T has extensive (4G/LTE) coverage throughout Mexico.

Due to the lack of a 2G network, locations covered by Telcel or Movistar México with 2G could mean no reception for AT&T.

However, you need to go to extremely remote areas for that to happen.

But, AT&T does have the highest 4G/LTE availability.

Below is AT&T's official coverage map:

Here is a coverage map produced by Speedtest:

SIM Card Price – AT&T Unidos México

You can get an AT&T SIM card for 150 MXN with 150 MXN credit and 2.3 GB of data or 200 MXN with 200 MXN credit and 3 GB of data in AT&T stores. Resellers, including grocery stores and convenience stores, sell SIM cards too. SIM cards are also available at select airports, including México City International Airport.

Note that AT&T offers VoLTE (Voice over LTE (4G)) if your phone supports it and if you have enabled it in the settings.

It is also possible to get an AT&T eSIM for the same price as a regular SIM card.

To use an AT&T eSIM, you need to have one of the following devices:

  • iPhone 11 Pro/11 Pro Max
  • iPhone 12/12 Mini/12 Pro/12 Pro Max

OXXO CEL is a FreedomPop México MVNO, which is a Telcel MVNO.

It is the mobile brand by the convenience store chain OXXO.

Why OXXO CEL decided to partner up with FreedomPop México instead of going directly to Telcel, I cannot tell.

OXXO, as a company, is also active in Brazil, Colombia, Costa Rica, Chile, Peru & the United States.

This is what you will learn about OXXO CEL:

* Coverage

* Topping Up Options & Methods + Balance Check

Coverage – OXXO CEL

OXXO CEL is a FreedomPop México MVNO, which in turn is a Telcel MVNO.

This means that OXXO CEL and FreedomPop México use the Telcel network and do not have their own mobile infrastructure.

It is unclear whether FreedomPop México, and OXXO CEL for that matter, have full access to the Telcel network or not.

So I will show you the coverage maps of FreedomPop México.

Here is the 2G coverage map:

Then we have the FreedomPop México 3G coverage map:

Then we have the 4G/LTE coverage map:

SIM Card Price – OXXO CEL

You can get an OXXO CEL SIM card for 29 MXN in OXXO convenience stores. However, you need to recharge at least 50 MXN to activate your SIM card, meaning the total cost is 79 MXN for your SIM card.

Bahías de Huatulco International Airport and Miguel Hidalgo y Costilla Guadalajara International Airport have OXXO stores near the airport selling OXXO CEL SIM cards.

Other Ways to Stay Connected When Traveling in Mexico

I would highly encourage anyone visiting Mexico to get themselves a Mexiacan SIM card – you will be saving a lot of money when you do so.

However, for some, getting a Mexican SIM card is not an option. For example, your device may be SIM-locked, meaning that you cannot use any SIM card other than the SIM card provided by your operator.

There are other ways to stay online while in Mexico, but they may not be cheap.

However, these methods may be more expensive than getting a SIM card from the local mobile operators.

International Roaming

International roaming is the most convenient way to stay connected when traveling in other countries because you do not have to buy a new SIM card, have to deal with SIM card registration regulations, nor have multiple phone numbers to deal with.

However, international roaming has proven to be expensive in many cases, especially compared to buying local SIM cards.

That is why many travelers are not fond of international roaming.

International roaming has its pros and cons. However, it is important to know how it works. This in-depth guide explains it all.

Find out whether your mobile operator has attractive roaming rates for Mexico here.

Using an International SIM Card or Travel SIM Card

International SIM cards are SIM cards made for the traveler in mind. Using them is often cheaper than international roaming.

However, they are almost always more expensive than using a local SIM card.

There are many other advantages and disadvantages of getting international SIM cards, which you can learn about here.

Using a Mobile Hotspot (Pocket WIFI)

Mobile hotspots, or pocket WIFI, are small devices that connect to the local operators of the country you are visiting.

Mobile hotspots are ideal for families or those traveling in a large group, as they allow you to connect multiple devices to one hotspot without the need of each traveler having to buy a SIM card.

You can either buy a mobile hotspot or rent one.

Using Free WIFI Networks

Using free WIFI connections is the cheapest way to stay connected because they are free.

The major downside of trying to use WIFI hotspots is that you will have to locate them, and they are not available on every corner in Mexico.

Make sure to protect your internet traffic with a VPN so that hackers cannot steal your personal data.


The Preferred Way to Stay Connected When Traveling in Mexico

Getting a SIM card from Telcel would do you well when considering a Mexican SIM card.
