Which local network does each travel eSIM use in Mexico?
A travel eSIM brand is not the same as the local network. In Mexico, eSIMs roam on one of three retail mobile network operators, or on the wholesale shared network that some virtual operators resell. The local network decides actual coverage, rural reach and 5G availability.
Mexico has three retail mobile network operators (MNOs) and one wholesale network:

- AT&T Mexico was formed after AT&T acquired Iusacell and Nextel Mexico in 2015 and has since invested in modernising and expanding its network. Source: Wikipedia, Telcel (retrieved 30 May 2026).
- Movistar (Telefónica) remains an independent operator; in 2022 it transferred its spectrum to the federal government and now runs its traffic over AT&T's network while keeping control of its own platforms. Source: Mexico Business News (retrieved 30 May 2026).
- Altan Redes / Red Compartida is a wholesale 4G-LTE and 5G shared network on the 700 MHz band; it does not sell to the public directly but supplies MVNOs and operators under a reference offer approved by the regulator. Source: Wikipedia, Red Compartida (retrieved 30 May 2026).
Mexico's telecommunications regulator is the Instituto Federal de Telecomunicaciones (IFT), which approved the Altan Redes wholesale reference offer in February 2018.

Does Mexico require ID to register a SIM?
This is the question that most often confuses travellers about Mexico, because the rules changed twice. Here is the verified position as of 30 May 2026.
For local Mexican lines: yes, registration is now required. A mandatory mobile registration rule took effect on 9 January 2026. All Mexican-issued mobile numbers, prepaid and postpaid, on a physical SIM or an eSIM sold by a Mexican carrier, must be linked to a person and a government-issued ID. Existing line holders have until 30 June 2026 to register, and unregistered numbers are set to be suspended from 1 July 2026. New lines must be registered within 30 days of activation. The identity record being built behind it is the CURP (the national population registry number). The Instituto Federal de Telecomunicaciones (IFT) is the enforcing authority. Source: Mexperience (retrieved 30 May 2026); Source: ID Tech Wire (retrieved 30 May 2026).
For foreign travel eSIMs: no, registration is not required. The 2026 rule applies only to numbers issued by Mexican mobile companies. A foreign-issued line, including an international travel eSIM from a brand like Airalo, Holafly or Nomad that roams on a Mexican network, does not need to be registered in Mexico. Source: Mexperience (retrieved 30 May 2026). This is the practical reason many visitors choose a travel eSIM rather than a local Mexican prepaid SIM: there is no in-country ID check or CURP step to complete.
Context: an earlier biometric registry was struck down. In April 2022, before the current rule, Mexico's Supreme Court declared an earlier national biometric mobile registry (known as PANAUT) unconstitutional, ruling that it failed to balance the need for data against the right to privacy. The 2026 rule is a separate, later measure. Source: Euronews (retrieved 30 May 2026).
How Mexico compares to its neighbours
Mexico sits in North America, bordering the United States to the north and Guatemala and Belize to the southeast. How a travel eSIM behaves here differs from those neighbours in a few important ways.
Mexico is part of the North America region alongside the United States and Canada, and shares a southern frontier with the Central American countries of Guatemala and Belize. Source: Wikipedia, Mexico (retrieved 30 May 2026). Unlike travel inside the European Union, there is no shared roam-like-at-home zone across North America, so a regional or North America plan, or a global plan, is usually what covers a trip that also touches the United States or Canada. A Mexico-only eSIM does not extend across the US border.
On the registration question, Mexico is now stricter for local lines than it used to be. Its 2026 SIM registration rule for Mexican-issued numbers is a meaningful change versus the more relaxed prepaid-SIM purchase that travellers historically encountered. The United States and Canada do not require the same CURP-style identity linkage for a tourist buying a local prepaid line, although their own rules vary by carrier. The key equaliser for visitors is that a foreign travel eSIM sidesteps all of these local registration regimes, in Mexico and in its neighbours, because it roams on a foreign-issued line.
Currency and language also shape the on-the-ground experience: Mexico uses the Mexican peso (MXN) and its primary language is Spanish, with the capital at Mexico City. Source: Wikipedia, Mexico (retrieved 30 May 2026). Most travel eSIM brands price in US dollars or euros regardless, so the peso rarely appears at checkout, but local top-up shops and Mexican-carrier SIMs will quote in pesos.
Unlimited data and fair use policy for Mexico eSIMs
Many travel eSIMs label plans as unlimited, but apply a fair use policy that reduces speed after a daily or total allowance. The table below compares the allowance, throttle speed, and hotspot rule for each brand once verified.

Frequently asked questions about Mexico eSIMs
Common traveller questions answered directly. Full FAQ content stays in the HTML so search and AI crawlers can read it.
Does Mexico require ID or registration for a travel eSIM?
No, not for a foreign travel eSIM. Mexico's 2026 SIM registration rule applies only to numbers issued by Mexican carriers, prepaid or postpaid, on SIM or eSIM. A foreign-issued travel eSIM that roams on a Mexican network is exempt, so there is no in-country ID or CURP step for visitors who use one.
What changed with Mexico's SIM registration law in 2026?
A mandatory registration rule took effect on 9 January 2026. All Mexican-issued mobile numbers must be linked to a person and a government ID, with the CURP as the identity record, enforced by the IFT. Existing holders have until 30 June 2026 to register or risk suspension. An earlier biometric registry, PANAUT, was struck down by the Supreme Court in April 2022.
Which local networks do travel eSIMs use in Mexico?
Mexico has three retail carriers, Telcel (América Móvil), AT&T Mexico and Movistar (Telefónica), plus the wholesale Altan Redes shared network. Telcel generally has the widest nationwide coverage. Each travel eSIM roams on one or more of these. The per-brand mapping on this page is pending verification.
Which eSIM has the best coverage in Mexico?
Coverage depends on which Mexican network the eSIM roams on. Telcel is generally regarded as having the widest nationwide reach, including rural and remote areas, so brands that connect to Telcel tend to do best outside the cities. Simscanner does not yet publish a verified per-brand coverage ranking for Mexico; the ranking table shows each brand's coverage score once verified.
Do I need a Mexico eSIM if my trip also includes the United States?
A Mexico-only eSIM does not extend across the US border, because North America has no shared roam-like-at-home zone like the EU. For a trip that touches both, a North America regional plan or a global plan usually covers you on both sides. Check each brand's country list before buying.
Can I use hotspot tethering on a Mexico eSIM?
Hotspot and tethering rules vary by brand. Some allow hotspot on all plans, some only on selected plans, and some restrict it on unlimited plans. The unlimited and FUP comparison on this page shows the hotspot rule for each brand for Mexico once the data is verified.
