Should I set up my US eSIM before or after arrival?

We recommend installing your eSIM before departure — it only takes about 90 seconds.

Before leaving, adjust some phone settings so your device automatically connects to local networks upon arrival. Your data plan activates the moment you land — even before you unbuckle your seatbelt!

If you forget, no worries — you can install anytime with a Wi-Fi connection after arrival.

It depends on your usage. Google Maps navigation, Instagram, Uber rides, FaceTime calls — all need data.

Fortunately, our plans are flexible. Start with 1GB and add more if needed.

General guidelines: Light use ~500MB/day, moderate use ~1-2GB/day, heavy use (video streaming) — consider our unlimited plan.

Will I pay roaming charges with a US eSIM?

Absolutely zero roaming charges! Your eSIM connects directly to US local networks, bypassing your home carrier entirely.

To prevent your carrier from charging roaming fees, make sure to disable data roaming on your primary SIM card before departure.

Enjoy your US trip worry-free — stay connected from Times Square to the Golden Gate Bridge!
