Fixed data
One total allowance for selected validity, not a daily reset.
Unlimited Lite
Shown as United States of America Unlimited. Compare daily full-speed allowance and reduced-speed terms.
Unlimited Essential
A balanced daily tier for maps, bookings and messages. Check exact full-speed terms.
Unlimited Plus
For heavier use, compare daily allowance, validity and hotspot terms. Plus is not Premium.
No Premium tier is selectable on the US product. Check data, speed, hotspot terms and live price on the United States plan page. More data does not extend signal offshore or on remote shores.
Detroit arrival
Save the airport on your ticket, accommodation address and onward transport bookings before leaving Wi-Fi. For a city-focused visit, see our Detroit eSIM guide. This page covers the wider Michigan trip. If you cross into Canada from Detroit, do not assume a United States-only plan covers the Canadian side.
Mackinac Island trip
Save ferry tickets, departure location, lodging details and return schedules offline. Check current operator rules and weather conditions. Do not assume a mobile signal on the ferry, offshore or at every island location; the eSIM does not include ferry transport or tours.
Sleeping Bear Dunes and Lake Michigan coast
Download trail maps, booking details and safety information before leaving connected towns. Coverage can vary on dunes, beaches and remote roads. Check current park access and weather conditions with local authorities, and do not rely on mobile data as your only emergency plan.
Need a US phone number too?
The data eSIM and the United States Virtual Phone Number are separate products. The virtual number is a monthly subscription that renews automatically. Check calling and messaging terms before buying; do not assume a number, calls or SMS come with the data eSIM.
Install and troubleshoot
- Choose a United States plan and validity, complete checkout and open the emailed QR code on another screen.
- Connect an unlocked eSIM-compatible phone to Wi-Fi. Add an eSIM from iPhone Cellular/Mobile Data settings or Android SIM manager/Network settings, then scan the code.
- Label the line AloOui and follow the delivery email. Do not delete the installed eSIM.
- On arrival, select AloOui for mobile data and follow the plan's activation instructions. If data fails, check validity and instructed roaming, toggle airplane mode and check any APN instructions. Visit the AloOui Help Center for help.
