_{Frequently Asked Questions}

_{Why not just use my own SIM or local Wi-Fi?}

Using your home SIM abroad can mean high roaming charges, and relying on free Wi-Fi can be patchy and insecure. eSIMs give you reliable, affordable data from the moment you land.

_{Can I use my data as a hotspot?}

Yes, all the plans we list allow hotspot and tethering with no restrictions — so you can share your data with friends and other devices.

_{How do I know which plan is right for my trip?}

Choose based on how long you're staying and how much data you'll use — unlimited plans are great if you want to do a lot of streaming or gaming, while capped plans might be preferable for smartphone minimalists. Check out our Find My Plan tool to understand your own data needs in seconds.

_{How do I know which plan is right for my trip?}

You’ll get fast, reliable coverage (4G/5G) in all the major U.S. hubs—Honolulu, New York, Miami, Las Vegas, Los Angeles, San Francisco, and more. Just keep in mind that in remote mountain or desert spots (think Page or the Grand Canyon), signal strength can taper off.
