Montana eSIM Glacier and Big Sky Travel Guide
Choose a US eSIM for a Montana mountain trip
Planning Glacier National Park, Whitefish or Big Sky? Compare AloOui's existing United States eSIM for mobile data where supported local coverage exists. Your QR code is emailed after purchase. This is a Montana travel guide, not a Montana-only product and not a promise of signal inside parks or on remote roads.

Fixed data
One total allowance over 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 tier for directions, bookings and messages when there is signal. Check full-speed terms.
Unlimited Plus
For heavier use where connected, compare allowance, validity and hotspot terms. Plus is not Premium.
No Premium tier is selectable on the US product. Compare data, speed, hotspot terms and current price on the United States plan page. Extra data cannot create mobile coverage in an unserved location.
Whitefish and Glacier National Park
Save the airport on your ticket, accommodation, park access details and offline maps before leaving a connected area. Check road openings, entry rules, weather and wildlife-safety notices directly with park authorities. Mountains and distance from supported networks can limit service on park roads, at trailheads and inside buildings. The eSIM does not include admission or transport, and should never be your only emergency plan.
Big Sky and Bozeman travel
Save lodging addresses, meeting points and return transport information while on Wi-Fi. Weather, terrain and congestion may affect service on mountain roads, ski areas and trails. Select enough validity for all days, but do not mistake longer validity or more data for wider coverage.
Border and long-distance routes
Glacier-area routes may approach Canada. A United States-only plan should not be assumed to work across that international border; check the selected plan's listed destinations first. Carry offline directions and emergency information for remote Montana drives.
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 its calling and messaging terms before buying; it cannot create a cellular signal where none exists.
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.
- Where a supported network is available, select AloOui for mobile data and follow your activation instructions. If data fails in a connected area, check validity and instructed roaming, toggle airplane mode and follow any APN guidance. Visit the AloOui Help Center for help. Settings cannot fix a place with no network signal.
