No Premium tier is selectable on this US product. Check data, speed, validity, hotspot terms and live price on the United States plan page. Extra data does not extend remote-area coverage.

Seattle arrival and city stay

Save the airport on your ticket, accommodation address and transfer details before leaving Wi-Fi. For city-specific tips, see our published Seattle eSIM guide. Indoor and underground reception can vary; keep essential travel details offline.

Mount Rainier and Olympic National Park

Before heading into either park, download maps, entry information and emergency details while connected. Mountains, forests and distance from supported networks can limit service on roads and trails. Check current park access, road status and weather with the relevant authorities. A data eSIM does not include park admission or guarantee reception at every viewpoint or campground.

Coastal and border itineraries

For Washington's coast, ferry journeys or a route toward Canada, save transport bookings and directions offline. Do not assume reception offshore or on a boat, and do not assume a United States-only plan works after a Canadian border crossing. Check listed destinations on the selected product before traveling internationally.

Install and troubleshoot

1. Choose a United States data plan and duration, complete checkout and open the emailed QR code on another screen.
2. Connect an unlocked, eSIM-compatible phone to stable Wi-Fi. On iPhone, open Settings > Cellular/Mobile Data > Add eSIM > Use QR Code. On Android, find Add eSIM in SIM manager or Network & internet; labels vary.
3. Scan the code, label the line AloOui and follow your delivery email. Do not delete the installed eSIM.
4. On arrival, select AloOui for mobile data and follow the selected plan's activation instructions. If data fails, check validity, mobile data and instructed roaming, toggle airplane mode, verify any APN instructions in your email and try automatic network selection.
