What Cell Coverage Is Like in Todos Santos 2026

What you actually need to know before you arrive: will your specific carrier work, where will you lose signal, how fast is the WiFi at vacation rentals, and what do you do if you need to work remotely or stay reliably connected? Here is the honest, specific answer to all of it.

The short version (for those in a hurry)

• In Todos Santos town: cell service is decent. T-Mobile and AT&T users will find reasonably reliable 4G signal in the town centre. Calls, texts, maps, and social media all work.
• In El Pescadero and Cerritos Beach: signal exists but is patchier. Expect 3G or weaker 4G in some spots. WiFi at your rental matters more than your carrier here.
• On Highway 19 between Cabo and Todos Santos: mostly fine, with a few dead zones in the desert stretches. Most visitors drive this road from Los Cabos International, if you are still figuring out flights and arrival logistics, read our guide What Airport Do You Fly Into for Todos Santos? 
• On rural roads, remote beaches, and anywhere off the highway: assume no signal until proven otherwise.
• For reliable internet at your villa: Starlink has changed everything. Properties in this area with Starlink are delivering 70–85 Mbps, which is genuinely fast. Check before you book.

Understanding the Baja cell landscape

Mexico has one dominant carrier: Telcel. It is the country’s largest network by far and provides the strongest and most consistent coverage across Baja California Sur. Almost everything else you experience on your US or Canadian phone, whether you’re on AT&T, T-Mobile, Verizon, or Rogers,  is routed through Telcel towers when you are in Mexico.

US and Canadian carriers offer roaming plans that work well in towns and cities, but signal often drops in remote areas. For stronger and more affordable coverage during a longer stay, purchasing a local Telcel SIM card is worth considering.

The key thing to understand is that your US carrier’s coverage in Baja is only as good as its agreement with Telcel, and not all agreements are equal. Some carriers have their own infrastructure in certain areas, while in most of the rest of Baja including Todos Santos, everything runs on Telcel’s network.

Carrier by carrier: what to expect

T-Mobile

T-Mobile is consistently the best-performing US carrier for travel to Mexico. Almost all T-Mobile postpaid plans include unlimited talk, text, and high-speed data in Mexico with no setup and no roaming charges, your phone works the moment you land.

Depending on your specific plan, you get between 5GB and 30GB of high-speed data, after which data continues at reduced speeds of up to 256 Kbps. For most travellers on a week or two-week trip, the high-speed allotment is enough for maps, messaging, social media, and light browsing. For remote workers or longer-stay guests, you will burn through it faster than expected, more on that below.

In Todos Santos, T-Mobile users on most postpaid plans typically get a usable 4G signal in town. In Pescadero and Cerritos, expect it to fluctuate.

AT&T

AT&T also includes Mexico roaming on most of its unlimited plans, with calls, texts, and data included. AT&T has its own towers in La Paz and the Cabo corridor, where service is strong. In most other areas of Baja including Todos Santos, it roams on Telcel towers, and speeds can be throttled to below 1 Mbps, fine for calls, texts, and emails, but not for video calls or heavy data use.

If you are an AT&T user, test your speeds when you arrive. If you are getting throttled on Telcel towers, a local Telcel SIM for data is worth the small investment.

Verizon

Verizon may work in resort and town areas but has less consistent coverage across Baja. Verify your international plan settings before you leave. Verizon users travelling to Todos Santos should absolutely activate international roaming before departure and consider carrying a backup option — either a Telcel SIM or a travel eSIM.

Canadian carriers (Rogers, Bell, Telus)

Canadian carriers include Mexico in their various travel add-on packages. Coverage in Todos Santos follows the same Telcel-dependent pattern as US carriers — decent in town, patchy in rural and beach areas. Check your specific plan for high-speed data limits before you go, as overage charges can add up quickly.

The best solution: a local Telcel SIM card

If you are staying more than a few days and want reliable data without worrying about roaming charges, picking up a local Telcel prepaid SIM is the easiest and most affordable option (other carriers like Oxxo Cel are also an option).

Prepaid SIM cards for tourists are available everywhere, any OXXO convenience store, local supermarkets, and anywhere you see a Telcel sign. You do not need to visit an official store. $10–$20 USD will typically last you a month of normal use, calls, maps, messaging, and everyday browsing. Heavy data users will burn through it faster, but for a typical vacation it is more than enough.

For remote work and anything data-intensive, a prepaid SIM alone is not the answer. WiFi at your rental is far more important than your cellular plan for video calls, large uploads, or a full working day online. Prioritise a property with fast, verified internet, ideally Starlink, and use your Telcel SIM for everything else when you are out and about.

Alternatively, a travel eSIM removes the need to swap physical cards. Services like Airalo, Gohub, and Holafly sell Mexico eSIMs that you download directly to compatible iPhones and Android devices before you leave home. You activate it on arrival and run it alongside your regular plan. This lets you use the eSIM for mobile data while keeping your home SIM active for calls, texts, and verification codes. Highly recommended for anyone who wants the convenience of their home number without paying roaming data rates.

WiFi in Todos Santos Mexico

For guests staying at a vacation rental in Todos Santos, El Pescadero, or Cerritos Beach, the most important connectivity question is not your carrier, it is your rental’s internet setup.

This has changed dramatically over the past two years. Starlink satellite internet is now widely available and operational across this area, and properties that have it are delivering genuinely fast speeds. Typical Starlink speeds in Todos Santos run 70–85 Mbps, fast enough for multiple simultaneous video calls, 4K streaming, large file uploads, and anything else you would do on a solid home internet connection.

For context, that is faster than the average home broadband connection in many US cities. It has transformed Todos Santos and Pescadero from “great for a getaway, difficult for remote work” into a legitimate base for digital nomads and location-independent workers.

Not every property has Starlink yet. Some still rely on local fixed-line internet, which is functional but slower and less consistent. Before you book any vacation rental for a trip where connectivity matters, whether you need to work, stream, video call family, or simply not feel cut off, ask specifically:

• Does the property have Starlink or fibre broadband?
• What are the typical download speeds?
• Is there a backup connection if the primary goes down?

Where you will and will not have signal

Todos Santos town: Workable 4G from T-Mobile and AT&T around the plaza and main streets. Google Maps, WhatsApp, and social media all function normally.

El Pescadero and Cerritos Beach: Good signal throughout both areas, though it becomes less consistent once you are on the shore itself.

Highway 19 (Cabo to Todos Santos): Mostly covered with a few dead zones in the open desert stretches,  typically 10–20 minute gaps. Download offline maps before you drive.

Highway 1 north toward La Paz: More variable. Expect genuine dead zones through the mountains and desert interior. Mountain and desert routes are where full dead zones are most likely, plan accordingly.

Remote beaches and dirt roads: Remote beach areas have weak signal or none at all. Prepare accordingly.

Practical tips before you go

Download offline maps. Google Maps and Maps.me both allow offline downloads. Download the Baja California Sur region before you leave home. This is the single most useful connectivity preparation you can make.

Enable international roaming before departure. Some carriers require you to activate international roaming manually, either through their app or by calling customer service. Do this before you board, not when you land.

Save key contacts and addresses offline. Your rental address, the nearest hospital (Hospital General in Todos Santos or the Hospital Salvatierra in La Paz for anything serious), and your emergency contacts should all be accessible without internet.

WhatsApp over SMS. The vast majority of locals, businesses, and service providers in Todos Santos communicate via WhatsApp. If you don’t have it already, install it before you travel. 

Carry a portable battery bank. Not specifically a connectivity issue, but power outages in Baja can happen, particularly in storm season. A charged power bank keeps your phone alive when the grid doesn’t.

Ask your rental about WiFi before you arrive. Especially if you are travelling for work, on an extended stay, or with children who will want to stream. A simple message to your property manager before check-in is all it takes.

Check the water too. Another common pre-trip question alongside connectivity, read our blog Can You Drink the Water in Todos Santos, Mexico?

The bottom line

Todos Santos is not off the grid. You will have a working phone, functional WiFi at virtually any quality vacation rental, and enough connectivity to navigate, communicate, and share your trip in real time.

What you will not have is the seamless, always-on connectivity of a major city. Signal drops in rural areas. Data speeds vary. Power cuts happen occasionally. And honestly, for most guests, that is part of the appeal, a place where you are present enough to notice the sunset rather than scrolling through it.

Come prepared with offline maps, a WhatsApp account, and a clear understanding of your carrier’s Mexico plan, and you will not be caught out. If connectivity is critical for your stay prioritise a rental with verified Starlink internet and you will be pleasantly surprised at how well it works.

And once you are connected and settled in, the best thing you can do is put the phone down. Read our guide Tours in Todos Santos, Mexico for ideas on how to spend your days out in the world.
