Los Cabos Fiber and Broadband: Which Developments Have Real Internet in 2026

I work remotely from Los Cabos, and the first thing I test in any property is the internet — not the view, not the pool, the internet. Because a $2 million condo with 5 Mbps DSL is not a vacation home for a remote worker. It is a very expensive place to be frustrated.

Here is the actual state of fiber and broadband infrastructure across Los Cabos in 2026, mapped by neighborhood and development. No marketing spin — just what providers are available, what speeds they deliver, and where you still need Starlink as your primary connection.

The Provider Landscape: Who Delivers What

Los Cabos has three primary broadband providers, each with different technology, coverage, and reliability profiles:

Telmex (Infinitum)

Mexico's national telecom, owned by América Móvil (Carlos Slim's company). Telmex offers both DSL and fiber-to-the-home (FTTH) service. The fiber product delivers symmetric speeds — meaning upload and download are the same — up to 200 Mbps. Pricing runs MX$499 to MX$899 per month ($28 to $50 USD). Telmex has the broadest coverage in Los Cabos' urban areas — San Jose del Cabo Centro, Fonatur, and most of downtown Cabo San Lucas are well-served. The weakness: Telmex is slow to extend fiber to newer suburban and resort developments, and their customer service reputation is what you would expect from a monopoly-era telecom.

TotalPlay

Grupo Salinas' fiber-optic broadband service. TotalPlay offers symmetric fiber up to 500 Mbps — the fastest wired speeds available in Los Cabos outside of private infrastructure. Pricing runs MX$599 to MX$999 per month ($33 to $55 USD). TotalPlay's coverage in Los Cabos has expanded significantly in 2026, with new buildouts along the Corridor and into suburban developments. Their network is newer than Telmex's, which generally means fewer legacy equipment issues. The weakness: coverage is still patchy — check availability for your specific address before committing to a property.

Megacable

Cable-based broadband offering download speeds up to 1 Gbps in select areas. Megacable is particularly strong in El Tezal and downtown Cabo San Lucas. Pricing runs MX$599 to MX$999 per month ($33 to $55 USD). The advantage: raw download speed. The disadvantage: cable infrastructure delivers asymmetric speeds (upload is significantly slower than download) and can suffer congestion during peak hours because bandwidth is shared among neighborhood users. For video conferencing, upload speed matters — a 500 Mbps download with 50 Mbps upload can bottleneck a multi-participant Zoom call.

Coverage by Area: The Honest Map

Here is what each area actually has:

San Jose del Cabo Centro — Excellent (95% fiber coverage)

The best broadband coverage in all of Los Cabos. Both Telmex and TotalPlay fiber are available in most of the downtown grid. Fonatur — the planned residential zone adjacent to downtown — has near-universal fiber coverage. If internet reliability is your top priority, San Jose Centro and Fonatur are the safest bets. See our Fonatur guide for the neighborhood details.

Cabo San Lucas Urban — Good (70-80% coverage)

Downtown Cabo San Lucas, the marina area, and El Medano have solid Telmex and Megacable coverage. El Tezal has particularly strong Megacable infrastructure — several sources report up to 1 Gbps available. Older neighborhoods in the Cabo hillsides may still have DSL rather than fiber — check the specific address.

The Tourist Corridor — Mixed (50-60% coverage)

This is where the coverage map gets complicated. The Corridor is a 20-mile stretch of Highway 1 between the two towns, and broadband availability varies wildly by specific development:

• Querencia — Private fiber infrastructure, dedicated bandwidth. Among the best internet in all of Los Cabos.
• Chileno Bay — Fiber infrastructure, reliable service.
• Cabo del Sol — Newer sections have fiber; older sections may rely on cable or DSL.
• Palmilla — Mixed. Some areas have fiber, others rely on cable. Upgrades are ongoing.
• Solaz, Zadún area — TotalPlay fiber expanding into this section in 2026.
• Rancho Paraiso — Cable-based, TotalPlay fiber arriving.

The pattern: newer developments built in the last 5 to 8 years generally have fiber in the ground because they were designed for it. Older developments are playing catch-up, and upgrades depend on the HOA or developer negotiating with providers to extend service.

East Cape — Limited (15-25% coverage)

The East Cape — including Los Barriles, Zacatitos, and Costa Palmas — is still largely Starlink territory. Telmex fiber reached Los Barriles town center in 2025 and has been expanding to Costa Palmas, but coverage outside the main towns is sparse. If you are buying in the East Cape for remote work, plan on Starlink as your primary connection with terrestrial fiber as a possible future upgrade.

Pacific Side — Limited (10-20% coverage)

Todos Santos town center has basic Telmex DSL and some cable service. Cerritos Beach and El Pescadero have minimal terrestrial broadband. Starlink is the primary internet solution for most Pacific Side properties. If you are buying in this area, factor Starlink into your budget and expectations — see our Starlink setup guide.

What Remote Workers Actually Need

Let me cut through the bandwidth confusion with what actually matters for different remote work scenarios:

• Email, Slack, documents: 5-10 Mbps down, 2-5 Mbps up. Even basic DSL handles this.
• Video conferencing (1-on-1): 5-10 Mbps down, 5 Mbps up. Any fiber or cable connection works.
• Video conferencing (group calls): 15-25 Mbps down, 10-15 Mbps up. This is where cable connections with low upload speeds can struggle. Fiber is strongly preferred.
• Software development, large file transfers: 50-100 Mbps symmetric. Fiber required.
• Video production, streaming: 100+ Mbps symmetric. TotalPlay 500 Mbps or Megacable 1 Gbps in supported areas.

The number most people ignore: upload speed. Cable connections advertise impressive download numbers (500 Mbps!) but upload speeds are often 10 to 20 percent of that. If you are on a video call sharing your screen, your upload speed is the bottleneck — not your download. Fiber connections deliver symmetric speeds (same up and down), which is why fiber is the strong preference for remote work.

Also consider latency — the time it takes for data to travel between your computer and the server. Fiber latency in Los Cabos runs 15 to 30ms to US servers. Starlink latency runs 25 to 60ms. Both are acceptable for video calls, but fiber is noticeably more responsive for real-time collaboration tools.

The Dual Connection Strategy

Serious remote workers in Cabo run two connections. This is not paranoia — it is insurance against losing a day of work to a provider outage.

• Primary: Telmex or TotalPlay fiber (whichever is available at your address)
• Backup: Starlink, configured as automatic failover

Total monthly cost: approximately $80 to $130 USD for both services. The Starlink equipment costs roughly $470 USD one-time. Many remote workers consider this a business expense that pays for itself the first time a Telmex outage hits during a client meeting.

For router configuration, a dual-WAN router like the TP-Link ER605 or Peplink Balance 20X automatically switches between your primary fiber and Starlink backup when it detects an outage. Setup takes about an hour and eliminates the manual switching that most people default to.

What to Verify Before You Buy

Do not trust the listing. Do not trust the agent (unless it is us). Verify internet yourself:

1. Ask the development which ISPs serve the property. Get the provider name and service tier, not "the internet is great."
2. Run a speed test during your visit. Use Speedtest.net at different times of day — morning, afternoon, and evening. Evening speeds (8 to 11 PM) reveal congestion issues that morning tests miss.
3. Ask the HOA about infrastructure plans. Is the development negotiating with TotalPlay or Telmex for fiber upgrades? Has the HOA invested in community-wide networking infrastructure?
4. Talk to current residents. Nothing beats asking someone who actually works from the property every day. They will tell you about the outages, the workarounds, and the reality.

The Bottom Line

Los Cabos internet infrastructure has improved dramatically since 2020. Fiber is genuinely available in most urban areas and an increasing number of resort developments. But the coverage is uneven, and the gap between best-case (symmetric fiber in Querencia) and worst-case (3 Mbps DSL in an older Corridor neighborhood) is enormous.

If you work remotely and your income depends on a reliable connection, prioritize San Jose del Cabo Centro, Fonatur, El Tezal, or a newer Corridor development with confirmed fiber. Budget for a dual-connection setup. And test the internet yourself before you sign anything — because "the internet is fine" is the second most common lie in Cabo real estate, right after "this property is a great investment."
