Best ISP in Mexico for 2026

Top ISPs in Mexico at a glance

ISP breakdown

1. Telmex Infinitum

Telmex Infinitum is Mexico's largest ISP with FTTH plans up to 1 Gbps. Fiber tests hit plan speed reliably. Legacy VDSL on older plans rarely exceeds 100 Mbps regardless of the advertised number.

2. Totalplay

Totalplay is Mexico's fastest-growing fiber ISP with symmetric plans up to 1 Gbps. Strongest in CDMX and Monterrey. Wired tests hit 900+ Mbps on the gigabit plan — competitive with Telmex Infinitum.

3. Megacable

Megacable is Mexico's largest cable ISP outside Telmex, strong in Guadalajara, Monterrey, and central Mexico. Cable plans cap upload; fiber plans are more consistent. Good mid-tier value.

How to check ISP availability at your address

ISP availability varies at the address level — two houses on the same street can have different technology (fiber vs cable vs DSL) available. Always check each provider's address-level tool, then run a speed test after installation to verify real-world performance.

Broadband landscape in Mexico

Mexico's fixed broadband penetration sits around 55% of households, well below the OECD average, but the gap is closing quickly as Telmex and Totalplay aggressively roll out fiber-to-the-home across the country's 32 states. Fiber (FTTH) has overtaken DSL as the dominant technology in most major cities, while cable (HFC) remains prevalent in areas where Megacable has a legacy footprint. The regulatory body overseeing the sector is the Instituto Federal de Telecomunicaciones (IFT), which sets rules on interconnection, open access, and consumer rights for internet services.

The urban–rural divide in Mexico is pronounced. In Mexico City (CDMX), Guadalajara, and Monterrey, consumers can choose among at least three fiber ISPs with gigabit plans. In rural states such as Oaxaca, Chiapas, and Guerrero, many homes still depend on mobile broadband or ADSL lines that rarely exceed 10 Mbps. The government's internet para todos program has expanded connectivity in underserved municipalities using a mix of satellite and fixed-wireless technology, but coverage remains incomplete.

Average fixed broadband download speeds in Mexico hover around 80–100 Mbps according to Ookla Speedtest data, below the global median of major economies. However, users on Totalplay or Telmex fiber in major metros regularly test above 300 Mbps, suggesting a large gap between what is technically available and what most households actually receive. Latency to US servers typically ranges from 20–50 ms from central Mexico.

How to choose the right ISP in Mexico

1. Check fiber availability at your exact address. Telmex, Totalplay, and Megacable all offer address-level coverage checkers on their websites. Enter your street, colonia, and postal code — availability can vary building by building, especially in dense urban areas.
2. Decide between Telmex Infinitum and Totalplay first. In most CDMX, Guadalajara, and Monterrey neighborhoods both ISPs are present. Totalplay's symmetric fiber is better for uploading, video conferencing, and gaming; Telmex has wider nationwide coverage and a larger support network.
3. Ask specifically for FTTH, not VDSL. Telmex still has VDSL (copper last-mile) plans in some areas sold under the Infinitum brand. Confirm with the agent that your address will receive a fiber-optic connection all the way to the building before signing a contract.
4. Factor in installation fees and contract terms. Most plans in Mexico carry a 12-month minimum commitment. Totalplay and Megacable sometimes offer the first month free or waive the router deposit during promotions — compare current offers on each provider's site.
5. Consider Megacable for mid-tier budgets. Megacable's cable plans in Guadalajara and central Mexico are competitively priced for 100–300 Mbps download speeds, even though upload remains asymmetric. Good choice if symmetry is not a priority.
6. Run a speed test after installation. Use a wired Ethernet connection to your router and test against a local Mexico City or Guadalajara server. If you see less than 80% of your advertised plan speed on wired Ethernet, contact your ISP to investigate the line.

Frequently Asked Questions

Is fiber internet widely available in Mexico?

Fiber-to-the-home is broadly available in Mexico City, Guadalajara, Monterrey, Puebla, and many other major cities. Telmex leads national coverage while Totalplay focuses on dense urban areas. Rural municipalities and smaller towns often rely on mobile broadband or DSL. The IFT's coverage maps can give you a rough sense of what technologies reach your municipality, but address-level checks with each ISP are always the most reliable method.

Which ISP is fastest in Mexico City?

In CDMX, Totalplay and Telmex Infinitum (on fiber) both deliver close to gigabit speeds on wired tests. Totalplay's symmetric 1 Gbps plan consistently tests at 900+ Mbps down and 900+ Mbps up, which is the highest real-world result among major ISPs in the capital. Megacable fiber is also present in parts of CDMX with strong download performance, though upload speeds are lower.

Do Mexican ISPs impose data caps?

Most fixed broadband plans from Telmex, Totalplay, and Megacable are sold as unlimited with no hard monthly data cap on their fiber and cable tiers. Some older Telmex VDSL plans include a "fair use" policy that can throttle speeds above a certain monthly threshold, but these clauses are rarely enforced aggressively on residential plans. Always confirm the exact terms when signing up, particularly for any plan under 100 Mbps which may still carry legacy cap language.
