Fixed data

One total allowance for selected validity, not a daily reset.

Unlimited Lite

Shown as United States of America Unlimited in the selector. Compare daily full-speed and reduced-speed terms.

Unlimited Essential

A balanced daily tier for maps, messages and bookings. Check the exact full-speed terms.

Unlimited Plus

For heavier use, compare daily allowance, duration 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 network coverage.

Boston arrival

Save the airport on your ticket, accommodation address and onward transport booking before leaving Wi-Fi. For city-specific travel details, see our existing Boston eSIM guide. This page is for a wider Massachusetts route, not another Boston-only guide.

Cape Cod coast

Check your departure point and travel time before heading to Cape Cod. Save lodging addresses, beach access rules and offline maps. Supported mobile signal can vary along coastal roads, beaches and inside buildings. The eSIM does not include transport or beach admission.

Martha's Vineyard and Nantucket

Keep ferry or flight reservations, meeting points and return schedules offline. Do not assume mobile coverage on a ferry, offshore or at every island location. Check the operator's current schedules and weather notices, and arrange a backup way to access tickets and contact details.

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, messaging and activation terms; do not assume calls or SMS come with the data eSIM.

Install and troubleshoot

  1. Choose a United States plan and validity, complete checkout and open the emailed QR code on another screen.
  2. 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.
  3. Label the line AloOui and follow the delivery email. Do not delete the installed eSIM.
  4. 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.
