Will I have signal in Olympic and Mount Rainier parks?

Only patchily. Both parks have large dead zones across their forests, coasts and mountain roads. Download offline maps, trail notes and tide tables before arriving, and treat the deeper wilderness as off-grid.

Does the eSIM cover the San Juan Islands ferries?

In the ferry towns like Anacortes and Friday Harbor, coverage is good for tickets and schedules. On the crossings and remote islands it thins, so download the ferry app and your maps in advance.

Good to know in Washington

Getting to the Olympic Peninsula and San Juan Islands often means ferries - use the Washington State Ferries app for real-time schedules and waits, and download it plus offline maps before you go, as terminals and crossings can lose signal.

Best time to visit Washington

July to September is the driest, warmest window with clear mountain views; the rest of the year is famously wet, though winter opens up skiing at Rainier and Baker.

Two simple ways to buy

Washington eSIM plans: unlimited, or by the GB.

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

Traveller streaming and browsing freely on an unlimited-data travel eSIM

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

3GB10GB20GB

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.

How much data do you need in Washington?

A rough, honest guide to sizing your Washington eSIM so you're not guessing. Most travellers in Washington are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Washington eSIM: your local data guide.

Washington State runs from Seattle's Pike Place Market and Space Needle to Mount Rainier's glaciers, the Olympic Peninsula's rainforests and the San Juan Islands. A Washington eSIM keeps ferry schedules, rideshare and trail navigation live, which matters when a morning coffee downtown can turn into an afternoon deep in a national park with no bars.

One eSIM for Washington and all of USA. It's the national USA eSIM — from $3.12/day with unlimited data, working the same in Washington as it does the moment you leave it.

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

Washington eSIM questions, answered.

No - this page covers Washington State on the Pacific coast, home to Seattle and Mount Rainier, not Washington DC on the east coast. That said, it's the national USA plan, so the very same eSIM works in both places and everywhere between.
