Compare US data plans for Colorado travel

No Premium tier is selectable on this US product. Check exact data, speed, validity, hotspot terms and current price on the United States plan page. A larger data allowance does not extend network coverage.

Denver arrival

Save the airport on your ticket, your accommodation address and transfer details before leaving Wi-Fi. For a Denver-only stay, see our published Denver eSIM guide. If continuing into the mountains, download offline maps, booking confirmations and emergency contacts while connected.

Rocky Mountain National Park and mountain drives

For park and scenic-road days, check current entry rules, weather, road closures and altitude considerations with local authorities before traveling. Reception may vary or disappear along mountain roads, trails and inside buildings. Do not rely on an eSIM as your only navigation or emergency method. A data plan does not include park entry or transport.

Aspen and winter or summer trips

Choose validity for the whole trip and keep lodging, transport and activity details offline. Weather, terrain and congestion can affect local service; do not assume data on every ski run, trail or remote road. Check current local access and safety information before setting out.

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 the delivery email. Do not delete the installed eSIM.
4. 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.
