Frequently Asked Questions
Everything you need to know about eSIMs, device compatibility, setup, messaging apps, and staying connected while traveling.
Military Travel & Choosing the Right Plan
Why should military travelers use an eSIM while overseas?
Reliable mobile data helps military members and families stay connected during PCS moves, deployments, TDYs, leave travel, and international trips. Having mobile data access can help with navigation, rideshare apps, translation apps, messaging, travel updates, hotel access, and staying in contact when local Wi-Fi is unreliable.
Why not rely only on Wi-Fi while traveling?
Public Wi-Fi can be inconsistent, slow, unsecured, or unavailable when you need it most. Mobile data provides more reliable access for maps, communication apps, transportation, and travel coordination while moving between airports, bases, hotels, and cities.
What can I use mobile date for while overseas?
Common uses include:
- Google Maps and Apple Maps
- WhatsApp and Signal FaceTime and Messenger calls
- Email and banking apps
- Translation apps Ride-share services
- Travel reservations and airline apps
- Streaming music or video
which plan should I choose: 10GB or 20GB?
A 10GB plan is usually enough for lighter travel use such as navigation, messaging, email, and occasional social media.
A 20GB plan may be better for longer stays, PCS transitions, video calls, streaming, hotspot use, or heavy daily usage.
Should I schoose a 15-day or 30-day plan?
15-day plans work well for shorter TDYs, vacations, or temporary trips.
30-day plans are often better for PCS moves, deployments, extended travel, or longer international stays.
Will I use more data than expected overseas?
Many travelers use more mobile data than expected because they rely more heavily on navigation, messaging apps, travel apps, and hotspot usage while abroad. Downloading maps and using Wi-Fi when available can help conserve data.
