Can I use the same eSIM for a trip to Napa or Sausalito?

Definitely — it's a national US plan, so the same eSIM works driving over the Golden Gate Bridge to Sausalito or up to Napa Valley wine country. You'll stay connected well beyond the city, with only occasional gaps on rural roads.

How much data suits a few days in San Francisco?

The city is compact and walkable, so between maps, transit apps, photos and browsing, 3–5GB covers a typical few-day visit. Scale up if you're hotspotting a laptop from cafés or streaming on longer day trips.

Good to know in San Francisco

San Francisco's microclimates are real — it can be sunny in the Mission and freezing at the Golden Gate the same afternoon — so check a live weather app before you set out. BART connects you straight from SFO into the city.

Two simple ways to buy

San Francisco eSIM plans: unlimited, or by the GB.

Every San Francisco eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in San Francisco — 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.

San Francisco eSIM: your local data guide.

San Francisco packs a lot into seven square miles, and a San Francisco eSIM keeps you oriented as you climb from Fisherman's Wharf to the murals of the Mission. You'll want live data to time a cable car, buy a Muni or BART ticket, and check whether Karl the Fog has swallowed the Golden Gate Bridge before you make the trip.

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

Landing at San Francisco International Airport (SFO)?

How much data for San Francisco

The city is walkable, so between maps, transit apps and photos, 3-5GB covers a few days; scale up to Unlimited if you'll hotspot a laptop from cafes or stream on longer day trips.

Peace of mind

Your San Francisco eSIM: data-only, zero bill shock.

Your San Francisco eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in San Francisco, no swapping your real SIM out.

Keep your number & WhatsApp

The eSIM is data-only and runs alongside your home SIM. Your number, iMessage and WhatsApp keep working exactly as they do at home.

No roaming bills, ever

Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.

One thing worth knowing

Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.
