If you spend much time at the Mexico City Airport (MEX) you'll want to know how to connect to the internet. Most Mexican airports do not offer free WiFi and, traditionally, it's been hard to connect to the internet at Mexico City's Benito Juarez International Airport.

Travelers visiting the Mexico City airport can access free WiFi, as well as an app with departures and arrivals, but the free part of it is time-limited. The airport network run by Totalplay (Salinas group) and Infinitum (Telmex) provides access to 20,000 users simultaneously in the airport's two terminals. Users have unlimited internet access for 45 minutes, after which they will need to purchase a service package. Clients of Telmex can access WiFi according to their plan.

While 45 minutes is helpful, you may find your connection interrupted in the middle of a work project or after reading just a few online articles. You'll probably want more time, especially if you are on a long layover.

VIP Lounges

Check WiFi options at VIP Lounges. For example, American Express operates 10 lounges exclusively for card members internationally and you'll find several in the Mexico City airport. The Centurion lounges offer WiFi.

Boingo Passpoint

You can connect to the internet at the airport with the Boingo Passpoint service, which is available for as little as $4.98 to start (it's a recurring charge that doubles after that first month). If you have that service, you'll be automatically connected when you are close to a hotspot and you can connect any four devices including laptops, tablets, and smartphones.

Cell Phone Service

Using your cell phone in Mexico is an option if you have purchased an International calling and data plan or if you have purchased a Mexican SIM card.

Alternatively, you can purchase a cheap phone in Mexico to use for making and receiving calls and texts, and keep your phone from home with the data and roaming off so that you just use it when you have WiFi.

The Starbucks Option

Customers of Starbucks get free, unlimited WiFi at the Mexico City airport. Purchase a cookie or a cup of coffee and you're in: Your username and password will be found on your receipt. It's not as easy as picking up WiFi at home, though.

The login page is in Spanish. After you select the "infinitum movil network, it will ask you which system you want to navigate with (navegar con). Use the default system, “Infinitum." Then fill in a username (usuario), Starbucks@infinitummovil,” and password (contraseña), found on the receipt.

Then enjoy free WiFi from anywhere in the airport for as long as you like. Some travelers have used the same password during several trips through the Mexico City airport, but it's not known how often Starbucks changes the password.

Some people report being bounced off the internet several times during their session so be sure and save (or photograph) your receipt with the password.
