Wherever you go, stay online withYonoSIM

Many travelers install shortly before departure or on arrival—follow your bundle's rules for activation. You'll need internet (Wi‑Fi is fine) to complete setup. See our step-by-step activation guide.

You need an eSIM-capable, carrier-unlocked device. Check our compatible devices list to confirm yours qualifies—compatibility is determined by your hardware, not YonoSIM.

We're the first travel eSIM store with a fully automatic 30-day refund. If your eSIM is unused within 30 days of purchase, we refund you automatically—no email, no ticket, no questions asked. You can also self-serve a refund on any unused eSIM anytime within 30 days. See our Terms for the fine print.

Every YonoSIM eSIM ships with data roaming included, but your phone keeps roaming switched off by default after install. Just go to Settings and turn on data roaming for the new eSIM. Tip: leave your home SIM's data roaming switched off to avoid surprise bills from your home carrier.

Yes. Your primary SIM stays active on your phone number for calls, SMS, and 2FA/verification codes—YonoSIM's eSIM handles data only. See our 2FA codes abroad guide for the full setup.

For most travelers, a Standard plan wins. Travel data is spiky—one heavy YouTube day, three Wi-Fi-mostly days—and a Day Pass gives you a fixed full-speed allowance each day (typically 500 MB–2 GB) before it slows down. A right-sized Standard plan usually costs less and gives you full speed on your heaviest day. See our standard vs Day Pass guide for the math.

Yes—Standard plans and Day Passes can both be topped up. When you're running low, open My eSIMs, tap Top up data, and pick a package. You keep the same eSIM: no new QR code, no reinstall, and no losing what's left. Standard plans top up with a data bucket; a Day Pass tops up by days, so you just add the extra days you need.
