Those USD conversions help put the local prices beside Roafly's USD pricing, but the products are not identical. Mexican prepaid service may include a local number, calls or SMS depending on the package, while buying it requires a local line, registration and potentially a separate SIM charge.
Can Tourists Buy a SIM Card in Mexico in 2026?
Yes. Foreign visitors can use Mexico's prepaid mobile market, and current operator registration procedures provide a passport route for people who do not have Mexican identity documents.
Mexico's mobile-line identification requirement took effect on January 9, 2026. Newly activated lines must be linked before normal service becomes available, while older lines follow the regulator's registration timetable.
Foreign visitors should have:
-
Valid passport from their country of origin
-
Unlocked and compatible phone
-
Access to the phone during activation
-
Accepted payment method for the chosen seller
-
Camera access when the operator's remote identity process requires it
The official Mexican mobile-line identification rules establish the nationwide framework.
Older Mexico SIM guides can therefore be misleading when they describe prepaid lines as something tourists can simply buy anonymously and start using immediately.
Best Local Prepaid SIM Options in Mexico
Telcel Amigo: useful prepaid choice, but check the SIM price
Telcel's Amigo prepaid service gives visitors a wide range of recharge amounts. Paquete Amigo Sin Límite 100 is a useful current benchmark because it costs MXN 100, includes 1.5 GB for general browsing and lasts 15 days.
The MXN 100 figure is the package price, not a safe estimate of the full amount required to walk away with a new physical Telcel SIM.
Check these points before paying:
-
Physical chip price
-
Package already included with the chip, if any
-
First recharge required at purchase
-
Full amount due for a working new line
-
Registration steps for a foreign passport
Telcel also includes calls, SMS and selected app benefits with qualifying Amigo Sin Límite packages. Those benefits belong to the local Telcel product and should not be assumed to apply to Roafly.
Tourists who value Telcel prepaid service should choose the package around trip length rather than buying a much larger allowance automatically. Someone staying week and someone staying month may need very different recharge amounts.
AT&T Prepago: straightforward 30-day package pricing
AT&T publishes a simple prepaid ladder, which makes the package component easier to understand. Its MXN 200 option provides 4 GB of general internet allowance for 30 days.
Current AT&T Prepago terms also include unlimited voice and SMS within the applicable package conditions. New activations are eligible for the regular prepaid offer, so tourists do not need to qualify for a contract plan just to use this benchmark.
The physical SIM remains a separate cost consideration. AT&T says customers can request a prepaid SIM in an AT&T store, while its standard chip terms require at least a MXN 50 recharge for activation unless the chip already comes with benefits.
Someone choosing the MXN 200 package should therefore think of the starting cost as:
MXN 200 recharge + the physical SIM price quoted at purchase.
The current package ladder and purchase steps are available on the official AT&T Prepago page.
AT&T also sells local eSIM products, but comparing every local digital-SIM variation would pull this guide away from its main purpose: helping tourists decide whether to buy Mexican prepaid service or use a travel eSIM instead.
Movistar Chip: lowest clearly published promotional entry price
Movistar has the clearest complete physical-SIM promotion among the options checked for this guide.
The dedicated Chip Movistar offer currently costs MXN 60 and provides 20 GB of general browsing data for 14 days, along with included minutes, SMS and selected app benefits. No additional initial recharge is required to receive those promotional benefits.
Using the Banco de México reference rate above, MXN 60 is roughly USD 3.52.
The attractive price comes with important restrictions:
-
Promotion runs from July 31 to September 20, 2026
-
Availability is limited to Canal Especialista
-
Terms can change when the promotion ends
-
Future recharges follow the prepaid offer available at that time
Those details make Movistar a strong short-trip value today, but not an evergreen MXN 60 recommendation.
Check the exact promotion on the official Chip Movistar page before buying.
Mexico SIM Registration: Passport and Identity Rules
Registration deserves attention before comparing another gigabyte or two.
New lines activated from January 9, 2026 require identity linking to receive service. AT&T and Movistar both explicitly allow foreigners to complete the process using a valid passport from their country of origin.
Movistar's current foreign-user procedure also includes a proof-of-life step using the device camera. AT&T supports remote or in-person linking and confirms that an unlinked new recharge line remains without normal service until registration succeeds.
The practical sequence looks like this:
-
Buy the prepaid SIM and receive the new line.
-
Insert and activate the SIM according to the operator's instructions.
-
Open the operator's official identity-linking process.
-
Submit the required passport information.
-
Complete any camera or identity-validation step requested.
-
Wait for successful linking confirmation before depending on the line.
Physical passport access is the safer approach. Relying on a stored photograph may fail when the operator needs to capture the document through its registration flow.
Tourists using the foreign-passport procedure should not assume that a Mexican CURP is required. Current AT&T and Movistar instructions specifically provide a route based on a valid foreign passport.
Where to Buy a SIM Card in Mexico
Official operator channels are the simplest place to separate the chip price from the recharge amount and get help with registration.
Useful buying routes include:
-
Telcel: Customer Service Centers and authorized sales channels
-
AT&T: AT&T stores and supported prepaid points of sale
-
Movistar: the channel specified for the current promotion or Movistar sales locations for other prepaid products
Retail availability varies, so seeing an operator logo at a convenience store does not prove that the exact package or promotional chip in this guide will be in stock there.
Ask the seller for the total amount due for a new active line before paying. The answer should make clear whether the quoted price covers the SIM, the recharge, or both.
Mexico City Airport creates a separate buying decision because airport retailers, stock and opening hours are location-specific. Travelers arriving there can compare SIM card options at Mexico City Airport instead of treating airport seller as representative of the whole country.
Local SIM vs Roafly eSIM in Mexico
Price alone does not decide this comparison.
Mexican prepaid service can be excellent value when you want a local line, included calls or SMS, or of the large promotional allowances offered by local operators. Registration and an in-country SIM purchase are the trade-offs.
Roafly removes the physical SIM purchase from the process. Owner-verified Mexico product details are:
-
Validity: 30 days
-
Listed local network(s): Telcel,AT&T
-
Service type: data-only
-
Hotspot/tethering: Supported across the purchased data allowance; no separate hotspot quota.
Keeping your primary physical SIM installed can also be useful when you still need access to your usual number while traveling. Roafly covers 200+ destinations, which may help on trips that extend beyond Mexico.
The listed Telcel,AT&T network information should not be interpreted as guaranteed automatic switching, guaranteed coverage, a speed promise or 5G confirmation.
Local prepaid service has the clearer advantage when you need:
-
Mexican mobile number
-
Local calling and SMS benefits
-
Very large promotional data allowances
-
Longer-term prepaid use
-
Service on a phone without eSIM support
Roafly fits better when you prioritize:
-
Setup without buying a physical SIM after arrival
-
Keeping your primary SIM in the phone
-
Data-only connectivity
-
Hotspot use from the purchased allowance
-
Less dependence on local shop stock and opening hours
Roafly focuses on visitors who mainly need mobile data without replacing their physical SIM. Current packages are available through Mexico eSIM plans.
Different connectivity methods suit different trips. Internet options for Mexico covers the wider choice between roaming, SIMs, eSIMs and Wi-Fi without turning this page into a general connectivity guide.
Does Your Phone Need to Be Unlocked?
Yes, when you plan to use a SIM or eSIM from a provider other than the carrier that originally supplied a locked device.
Carrier-locked phones can reject another mobile profile even when the device supports the right SIM format. eSIM compatibility is a separate requirement, so an unlocked phone does not automatically mean eSIM support.
Checking both issues before departure saves time at the counter. Use phone compatibility in Mexico when you need the device-specific details.
Which Mexico SIM Option Fits Your Trip?
Lowest currently verified physical-SIM entry price: Movistar's MXN 60 Chip promotion stands out while the current offer remains active. The 14-day validity and September 20 end date make it especially relevant to shorter trips.
Straightforward 30-day local package: AT&T's MXN 200 / 4 GB benchmark works well for a typical multi-week stay, though the separate SIM price still needs to be added.
Telcel prepaid preference: Paquete Amigo Sin Límite 100 gives a useful 15-day starting point at MXN 100. Confirm the chip price before treating that amount as your total purchase cost.
Data with less arrival-day setup: Roafly avoids the local physical-SIM purchase and lets compatible travelers keep their primary SIM installed. Local prepaid remains the stronger choice when a Mexican number or local voice service matters.
FAQ
Can foreigners register a prepaid SIM in Mexico with a passport?
Yes. Current AT&T and Movistar registration procedures explicitly allow foreign users to link a mobile line using a valid passport from their country of origin.
Telcel's tourist eSIM registration also accepts a valid passport and requires identity verification before service can be used.
Do tourists need a Mexican CURP to register a SIM?
Tourists using the published foreign-user routes from AT&T and Movistar can register with a valid foreign passport. Those procedures do not instruct foreign visitors to obtain a Mexican CURP first.
Operator processes can change, so use the current registration instructions instead of relying on older travel articles.
How much is MXN 200 in US dollars?
Using the Banco de México FIX reference of MXN 17.0218 per USD, MXN 200 equals roughly USD 11.75.
Actual card, ATM and cash-exchange rates may differ from the reference rate.
Is buying a SIM at Mexico City Airport cheaper than buying in the city?
No reliable nationwide rule supports that assumption. Airport and city prices should be compared using the exact seller, SIM fee, recharge and promotion available on the day you buy.
Convenience may matter more than a small price difference after a long flight, but the complete checkout amount is what should be compared.
Is a local SIM cheaper than Roafly in Mexico?
Some current local offers have a lower headline price, especially Movistar's temporary MXN 60 promotion. The comparison changes you consider trip length, SIM fees, registration, whether you need a Mexican number and how much data you actually need.
Roafly solves a different problem: data connectivity without a physical SIM swap or local shop purchase.
Final Recommendation
Movistar currently has the most compelling verified low-cost physical-SIM promotion for a short visit, provided the Canal Especialista restriction works for your trip. AT&T offers a clearer 30-day prepaid benchmark, while Telcel remains a practical choice when its Amigo packages better match your preferred local service.
Roafly becomes more attractive when convenience matters more than obtaining a Mexican number. Setup without a physical SIM purchase, 30-day validity and hotspot support make it easier to prepare mobile data without managing a new local prepaid account after arrival.
Whichever route you choose, compare the complete upfront cost rather than the headline recharge alone. SIM price, mandatory first payment, validity and registration requirements can change the real value substantially.
Roafly publishes this guide and offers the travel-eSIM alternative discussed above.
