How this is estimated. Coverage comes from the FCC National Broadband Map (Broadband Data Collection): each U.S. provider files a propagation model of where it claims 4G LTE service, published per ~0.1 km² hexagon for outdoor and in-vehicle use (the strongest of the two is used here). Hexagons modelled at −100 dBm or stronger count as 4G/5G, weaker filed coverage counts as degraded signal, and no filed hexagon counts as no signal. This is a provider filing, not a field measurement — real signal varies with terrain, weather and network load.

Frequently asked questions
How much data do I need for Pacific Coast Highway (California SR-1, San Francisco–Los Angeles)?
Aim for at least 500 MB a day — comfortable headroom for daily navigation, booking accommodation, messaging home and uploading photos. The featured plan is picked on exactly that rule; size up if you stream, video-call or share your connection.
When do the plan days start counting?
On first use — installing the eSIM and connecting starts the clock, not the purchase date. You can safely buy weeks before your trip.
Does my phone support eSIM?
Most phones released since 2019 support eSIM, including iPhone XS and later, Google Pixel 3 and later, and most recent Samsung Galaxy models. Your phone must also be carrier-unlocked.
What if I change my mind after buying?
Uninstalled eSIMs qualify for a full self-service refund within 14 days of purchase — no questions asked. Once the eSIM is installed on a device it can no longer be returned. See the refund policy.
