Mexico City Airport (MEX) SIM Card Options 2026: Stores, Registration, WiFi & eSIM

Quick answer: Yes, prepaid SIM cards are reliably available at Aeropuerto Internacional Benito Juárez de la Ciudad de México (Mexico City International Airport), with official Telcel locations in Terminals 1 and 2. If you need a Mexican number, a staffed local-SIM counter is the practical choice; if you mainly need data or arrive outside useful store hours, an eSIM avoids searching for physical stock.

Mexico City Airport SIM card options at a glance

Airport stores, package prices and opening hours were checked on August 13, 2026 and may change without notice.

AICM's official communications directory confirms Telcel and MOBO mobile-phone outlets at MEX. Telcel is listed in T1 from 09:00–19:00 and in T2 from 07:00–22:00; AICM also lists multiple MOBO locations with longer operating hours.

The main uncertainty is price, not whether mobile-phone sellers exist. AICM does not publish a complete tourist checkout total combining the physical SIM, prepaid package and any retailer service charge.

Where to buy a physical SIM at MEX

Telcel — Terminal 1

Verdict: The clearest staffed option for T1 arrivals who specifically want a Mexican Telcel number.

• AICM lists Telcel on the upper floor of Terminal 1, open daily from 09:00 to 19:00.

• AICM's broader commercial directory places the Telcel unit in the Terminal 1 financial center and also gives 09:00–19:00 hours.

• Ask for the SIM price, package price and final amount before paying.

• Complete the required identity-linking process and test mobile data before leaving the counter.

Telcel — Terminal 2

Verdict: The strongest T2 choice, with longer official opening hours than the T1 Telcel location.

• AICM lists Telcel on the ground floor of Terminal 2.

• Published hours are 07:00–22:00 daily.

• The communications directory currently identifies the unit as ALL32.

• Because AICM's separate commercial listings are not fully consistent about unit numbering, use the terminal and floor details and confirm the current position with airport information if signage differs.

MOBO — observed AT&T availability

Verdict: A useful alternative when you find an open MOBO counter, but operator stock should be checked before relying on it.

• AICM officially lists numerous MOBO mobile-phone shops across T1 and T2, including several locations with early or late hours.

• A July 2, 2026 on-site report observed AT&T SIM cards at selected Terminal 1 MOBO counters near Puertas 3, 5 and 7.

• Observed airport availability, checked July 2, 2026.

• AICM does not publish the current operator inventory for each MOBO branch, so AT&T stock is not guaranteed at every counter.

OXXO and 7-Eleven — late-hours backup

Verdict: Potentially convenient outside Telcel shop hours, but less dependable for stock and setup assistance.

• AICM confirms OXXO and 7-Eleven locations in Terminal 1, including 24-hour branches.

• Recent on-site evidence observed Telcel SIM cards at selected T1 OXXO and 7-Eleven stores.

• Observed airport availability, checked July 2, 2026.

• Buying the card and completing registration are separate steps, so confirm that your line is fully active before depending on it.

How much does a SIM card cost at Mexico City Airport?

A reliable complete airport checkout price is not currently published. Recent on-site reporting from July 2, 2026 cited Telcel prepaid package examples of about MXN 300 for roughly 5 GB and MXN 500 for a larger data allowance, but those figures are package references rather than guaranteed SIM-plus-package airport totals.

Telcel's official prepaid pages continue to list Amigo Sin Límite packages in denominations including MXN 300 and MXN 500, while activation is supported through channels such as customer centers and authorized distributors.

Before paying at MEX, confirm:

• the physical SIM or starter-card charge;

• the prepaid package or recharge amount;

• any activation, setup or retailer service fee;

• the final amount payable;

• validity and included general-purpose data.

Do not treat a nationally published Telcel package price as the complete airport purchase price. Airport-counter payment methods are also not reliably published for every seller, so carrying an alternative payment method is sensible.

SIM registration in Mexico: what tourists need in 2026

Mexico now requires mobile lines to be associated with an identified user. The official DOF mobile-line rules state that foreigners can be identified using their name, country of origin and passport number.

For an arriving tourist, the practical requirements are:

• Bring a valid passport. Foreign users can use passport information to link a Mexican mobile line under the current rules.

• Expect registration before normal use. Telcel states that the identification requirement has applied to mobile lines since January 9, 2026, including tourist eSIMs.

• Complete any identity checks requested by the operator. Telcel's remote process may use passport capture and a liveness check.

• Do not assume inserting the SIM completes activation. Confirm that the line has been linked successfully.

• Test the connection before leaving a staffed shop. This is especially useful if you need immediate data or a Mexican number after landing.

Older Mexico SIM guides that say tourists can simply buy an anonymous prepaid SIM are therefore no longer a reliable description of the 2026 process.
