Fixed data
A total allowance for selected validity, not a daily reset. The US selector has a 1GB/7-day option and larger fixed allowances.
Unlimited Lite
Shown as United States of America Unlimited in the selector. Compare the daily full-speed allowance and reduced-speed terms for lighter use.
Unlimited Essential
A balanced daily tier for maps, messages and bookings. Review exact full-speed and continued-data terms.
Unlimited Plus
Compare this daily tier for heavier use. Confirm its allowance, validity and hotspot terms; Plus is not Premium.
No Premium tier is selectable on this US product. Check data, speed, duration, hotspot terms and current price on the United States product page. Fixed data has a total allowance; the Unlimited tiers have their own daily full-speed terms.
Arriving in San Diego
Save the airport shown on your ticket, your accommodation address and transfer details before leaving Wi-Fi. After following your selected plan's activation guidance, supported mobile data can help with directions and contacting your host. Confirm pickup points, fares and schedules with your transport provider. The eSIM does not include airport transport or guarantee reception inside every terminal.
Coastal days and cross-border plans
Use supported data for directions to your hotel, meetings and booked city visits. Save tickets and offline maps before heading out, especially for areas where local network service may vary. A United States-only plan should not be assumed to cover Mexico, even on a short trip from San Diego; check listed destinations and buy appropriate coverage before crossing the border.
Need a US phone number too?
The data eSIM and the United States Virtual Phone Number are separate products. The virtual number is offered as a monthly subscription that renews automatically. Check its calling, messaging, activation and acceptable-use terms before purchasing; do not assume a number is included with your eSIM.
