Will I have signal on the long desert drives?

Towns and the main highways have coverage, but there are genuine dead zones on the empty desert stretches between them. Download offline maps and tell someone your route before setting off.

Is one eSIM enough for Puerto Peñasco and Hermosillo?

Yes. It's a single national Mexico plan, so the same eSIM covers the whole state, beaches, capital and colonial towns alike, and everywhere else in Mexico you travel.

Good to know in Sonora

Sonora's desert highways run for long, remote stretches with no signal, few services and searing summer heat. Fuel up, carry water, and download offline maps before setting out, as you can't count on live navigation between towns.

Best time to visit Sonora

October to April brings comfortable desert temperatures; summers are extremely hot, often topping 40°C, so most travellers visit outside the peak-heat months.

Two simple ways to buy

Sonora eSIM plans: unlimited, or by the GB.

Every Sonora eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Sonora — you can always top up or switch on your next trip.

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Sonora eSIM: your local data guide.

Sonora sweeps from the capital Hermosillo across cactus desert to the Sea of Cortez beaches of Puerto Peñasco (Rocky Point) and San Carlos, down to the silver-era colonial town of Álamos. A Sonora eSIM helps you navigate the long, empty desert highways, book fishing and beach trips on the Sea of Cortez, and find shade and fuel stops on the drive from the Arizona border.

One eSIM for Sonora and all of Mexico. It's the national Mexico eSIM — from $3.04/day with unlimited data, working the same in Sonora as it does the moment you leave it.
