Fixed data
A total allowance for the selected validity, not a daily reset. The US selector includes a 1GB/7-day choice and larger fixed allowances.
Unlimited Lite
Shown as United States of America Unlimited in the selector. Compare its daily full-speed allowance and reduced-speed terms for lighter use.
Unlimited Essential
A balanced daily tier for city maps, messages and bookings. Check its 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 United States product. Check exact data, speed, duration, hotspot terms and live 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 Chicago
Save the airport on your ticket, accommodation address and transfer instructions before leaving Wi-Fi. Chicago has more than one commercial airport, so follow the arrival details on your booking rather than assuming a particular terminal. After your selected plan's activation steps, supported data can help with directions and contacting your host. Confirm transport schedules, fares and meeting points with the operator; an eSIM does not include an airport transfer.
City days and onward US travel
Use supported data for directions between your hotel, meetings and booked visits. If you continue to another US city, choose validity for the full itinerary and download essential tickets and offline maps before travel. Local coverage and speed vary by network, building, congestion and device. Do not assume that a US-only plan covers travel into Canada or Mexico; review listed destinations before crossing a border.
Install and troubleshoot
- Choose a United States plan and duration, complete checkout and open the emailed QR code on another screen.
- 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.
- Scan the code, label the new line AloOui and follow the delivery instructions. Do not delete the installed eSIM.
- On arrival, select AloOui for mobile data and follow the selected plan's activation guidance. 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. Visit the AloOui Help Center for assistance.
