Cell Phones, Internet, and Staying Connected in Los Cabos: The Complete 2026 Guide

You can run a business from Cabo — I've watched dozens of people do it, from real estate coaching calls to corporate executive roles to running e-commerce operations. But you need to understand the connectivity landscape first: which carriers actually work in Baja, where fiber reaches, where it doesn't, and why one satellite internet company fundamentally changed the real estate equation for half the peninsula.

Cell Phone Service in Los Cabos

Using Your US or Canadian Phone

The good news: your US or Canadian cell phone works in Los Cabos out of the box on most current plans. T-Mobile, AT&T, and Verizon all include Mexico in their standard North American roaming — calls, texts, and data work without additional per-use charges. T-Mobile tends to be the most generous with Mexico data, often providing full-speed roaming, while Verizon and AT&T plans vary.

The catch for full-time residents: carriers define these as "roaming" plans, meaning they expect your phone to be used primarily in the US/Canada. If the majority of your usage consistently occurs in Mexico over several months, your carrier may flag the account or throttle speeds. This rarely becomes an issue for snowbirds or part-time residents, but full-time Mexico residents should eventually get a Mexican SIM.

Getting a Mexican SIM Card

The standard move for full-time expats: buy a Telcel prepaid SIM card (chip Telcel) at any Telcel store, OXXO convenience store, or electronics retailer. You'll need:

• An unlocked phone (confirm with your US carrier before traveling; iPhones purchased in the US after 2015 are generally unlockable upon request)
• A valid ID (passport works)
• 100-200 pesos ($6-$12 USD) for the SIM and initial airtime

Telcel prepaid plans (Amigo Recarga) are loaded by purchasing airtime at OXXO, 7-Eleven, or through the Mi Telcel app. Plan options:

• Basic ($6/month): 1-2 GB data, limited calls/texts. Fine for casual use.
• Standard ($18-$30/month): 6-10 GB data, unlimited domestic calls, unlimited calls to US/Canada, social media data (WhatsApp, Facebook) that doesn't count against your cap.
• Premium ($30-$47/month): 15-20+ GB data, everything unlimited including US/Canada calls. This is what most remote workers use.

Many expats keep two SIMs — their US number on eSIM for the contacts and accounts that need it, and a Telcel physical SIM for daily Mexican use. Modern iPhones and most Android flagships support dual-SIM (one physical + one eSIM).

Coverage Map Reality

Telcel dominates Baja California Sur coverage. In central Cabo San Lucas, San Jose del Cabo, and the Corridor, you'll get full 4G/LTE (and 5G in some areas) from both Telcel and AT&T Mexico. Where they diverge:

• East Cape (Los Barriles, Zacatitos, Costa Palmas): Telcel has functional coverage along the main highway and in Los Barriles. AT&T Mexico is spotty to nonexistent. Dead zones exist between towns.
• Pacific Side (Todos Santos, El Pescadero, Cerritos): Telcel has coverage in the towns. AT&T is weaker. The stretch between Cabo San Lucas and Todos Santos has gaps.
• Sierra de la Laguna interior: No coverage from any carrier. If you're hiking into the mountains or visiting remote ranchos, you're offline.

Home Internet Options

Fiber Optic (Central Los Cabos)

In the urban footprint of Cabo San Lucas, San Jose del Cabo, and the Corridor, fiber-optic internet is available from three primary providers:

Provider	Technology	Speed Range	Monthly Cost	Coverage
Telmex (Infinitum)	Fiber / DSL	20-200 Mbps	$35-$65 USD	Broadest — most addresses served
Totalplay	Fiber	100-500 Mbps	$45-$88 USD	Growing — newer fiber network
Megacable	Cable / Fiber	100-300 Mbps	$40-$70 USD	Select areas

Fiber availability is address-specific. The provider's coverage map may show your area as served, but the actual connection depends on whether fiber has been pulled to your street and building. Always confirm with an in-person technician visit before signing up — the call-center rep and the reality on the ground sometimes disagree.

Most gated developments and HOAs have existing relationships with one or more providers. When buying a condo or home, ask the HOA which internet providers serve the development and what speeds residents actually get — the advertised speed and the delivered speed aren't always the same.

Starlink: The Game Changer

Starlink transformed the connectivity landscape for rural and semi-rural Baja California Sur properties. Before Starlink, buying a property on the East Cape or the Pacific side outside the towns meant accepting dial-up-era internet (3-10 Mbps DSL at best, nothing at worst). That was a dealbreaker for remote workers and a lifestyle limitation for everyone else.

Now:

• Hardware: ~$599 USD one-time for the dish and router
• Monthly: ~$120 USD
• Speeds: 50-200 Mbps download, 10-20 Mbps upload, 20-40 ms latency
• Setup: Self-install in 30 minutes — plug in, point at the sky, connect
• Availability: Anywhere in BCS with a clear view of the sky

For properties in Los Barriles, Zacatitos, El Pescadero, Cerritos, or rural lots outside the urban fiber footprint, Starlink is the primary internet solution. For properties in central Cabo with fiber access, Starlink serves as the ideal backup — a separate system on a different infrastructure that keeps you online when Telmex goes down (which happens more often than the advertised 99.9% uptime suggests).

The Remote Worker's Setup Guide

If you're working from Cabo and your livelihood depends on internet connectivity, here's the setup I recommend based on what actually works:

The Redundancy Stack

1. Primary: Fiber internet (Telmex or Totalplay, 100+ Mbps) for daily work — fast, stable, low latency.
2. Backup: Starlink on a separate circuit — different infrastructure, different failure modes. When Telmex goes down (and it will, usually for 30 minutes to a few hours), Starlink keeps you on your Zoom call.
3. Emergency: Telcel hotspot from your phone — 4G/LTE tethering gets you through a meeting if both wired connections fail simultaneously (rare but not impossible during chubascos or CFE outages).
4. Power: UPS battery backup on your router and modem — a $50-$150 UPS (available at Office Depot Cabo or ordered from Amazon Mexico) gives you 30-60 minutes of internet during a CFE power outage, which covers most brief interruptions.

Coworking Spaces

San Jose del Cabo's coworking scene is growing. Several spaces in the downtown area and near the art district offer day passes ($15-$25 USD) and monthly memberships ($150-$300 USD) with dedicated fiber internet, backup power, air conditioning, and the kind of professional environment that makes video calls feel like you're in an office rather than a beach house.

WhatsApp: The Default Communication Tool

This is the single most important connectivity adjustment for life in Mexico: WhatsApp is the default communication platform. Not email, not phone calls, not text messages. WhatsApp.

Your real estate agent communicates via WhatsApp. Your property manager sends photos and updates via WhatsApp. Your gardener, housekeeper, plumber, and electrician all use WhatsApp. Restaurants take reservations via WhatsApp. Some government offices even accept document submissions via WhatsApp.

If you're not already a WhatsApp user, download it, set it up with your phone number, and start using it before you arrive. It's free, encrypted, works on WiFi (important for areas with weak cell signal), and it's how Mexico communicates.

Connectivity Tips for New Residents

• Get a Telcel SIM in your first week. Don't wait until your US roaming plan causes problems — the cost is negligible and the coverage is better.
• Check internet at the property before you buy. Ask the HOA, ask the neighbors, do a speed test during your visit. "Internet available" on a listing doesn't tell you whether it's 10 Mbps DSL or 200 Mbps fiber.
• Budget for Starlink if you're buying outside central Cabo. Add $599 + $120/month to your carrying cost calculations for any East Cape or Pacific-side property.
• Set up autopay in pesos. Telmex, Telcel, and CFE all offer autopay, which prevents service interruption from a missed bill while you're traveling. Set them up through your Mexican bank account or Telcel/Telmex apps.
• Download offline maps. Google Maps and Apple Maps both support offline map downloads. Download the Los Cabos region before you need it — cell signal drops on remote stretches of highway, and GPS navigation without data is a lifesaver.
