Worked the second I landed.

I was online before my luggage hit the belt. No app, no setup stress, no €10/day roaming bill from my carrier. Total game changer.

Sarah J.New York · Spain trip Verified

Cheaper than I thought, actually fast.

Used it across Thailand, Japan, and Singapore. Same eSIM, full 5G, never throttled. Saved me hundreds versus my carrier's roaming.

Michael C.San Francisco · Asia tour Verified

Finally a no-fuss travel eSIM.

I switch countries every few weeks. Uonfly is the only one I've stuck with — install once, top up in seconds, never had a dead day.

Emma W.London · Digital nomad Verified

Saved me at the airport.

Forgot to set anything up before flying. Bought it standing at baggage claim, scanned the QR, was online in under a minute.

David M.Toronto · Thailand Verified

Worked across 5 countries seamlessly.

Bought a Europe regional plan. Crossed borders by train, signal just kept working. Maps, Uber, WhatsApp — never lost connection.

Sophie A.Sydney · Europe trip Verified

Real customer support is rare.

Had a question late at night before a flight. Got a real human reply within minutes — not a bot, not a 24-hour ticket. That's why I keep buying.

Frequently asked questions

Go to help center
Will my phone work with Uonfly eSIM?

Most phones from 2018 onward support eSIM. That includes iPhone XR/XS or newer, Samsung Galaxy S20+, Google Pixel 3+, and most modern Android flagships.

Two things to check: your phone needs to be unlocked (not locked to a carrier contract), and eSIM must be enabled. We run an automatic compatibility check before you pay — so there are no surprises after purchase.

When should I activate my eSIM?

Install it before you fly, but don't activate until you land. Most plans only start counting once your phone first connects to a network in the destination country.

Step-by-step: scan the QR code at home → eSIM installed → keep airplane mode on or your home SIM as primary → land → switch the eSIM on → connected.

Can I keep using WhatsApp on my normal number?

Yes, absolutely. WhatsApp, iMessage, and most messaging apps run on internet — not on cellular voice. Your home number stays linked to your physical SIM (or eSIM), the Uonfly eSIM just provides the internet connection.

Tip: keep your home SIM active but turn data roaming OFF for it, so you don't accidentally get charged.

How fast do I get my eSIM after payment?

Instantly. The QR code lands in your inbox within seconds of payment. If it's not there in 60 seconds, check spam — and if still nothing, contact support and we'll resend immediately.

Can I use the eSIM as a hotspot?

Yes — tethering and hotspot are fully supported on all our plans. Share with your laptop, tablet, or travel buddies. Speed and stability stay the same as your phone connection.

What if it doesn't work after I land?

That's exactly when good support matters. Reach us via the in-app chat, email, or WhatsApp — average reply time is under 3 minutes, 24/7.

If we can't get you online within an hour of you reaching out, you get a full refund, no questions asked. That's our 30-day money-back guarantee.

Can I use one eSIM in multiple countries?

Yes — we offer regional plans covering Europe (45+ countries), Asia (20+ countries), Latin America, and global. Buy once, cross borders, stay connected.

For longer multi-country trips, our Global plan works in 130+ countries on a single eSIM.

Is there speed throttling or a fair-use policy?

On our Unlimited plans: 2 GB highspeed per day, then unlimited at 1 Mbps for the rest of the day. Resets at midnight local time. We tell you this before you buy — not in fine print after.

On regular GB plans (1 GB, 5 GB, 10 GB...): no throttling at all. You get what you paid for.
