Online instantly in Rome without hunting for a SIM at the airport. Google Maps guided me reliably through the alleys of Trastevere. Exactly how it should be.
BEST decision ever!! 🙌 Posted from the beach, called from the Sagrada Família, all without a single dropout. Never again without!!
It just worked. Nothing to complain about.
Installation went great, network was fast. Only briefly a bit slower on the canal cruise, otherwise super.
We spent ten days in Lisbon and Sintra. At first I was sceptical whether an eSIM would really be enough – but honestly: I didn't miss my regular Wi-Fi once. Uploaded photos straight from the miradouro, looked up restaurants in the evening, booked train tickets in the morning. All smooth. Again on the next trip.
Two-minute setup, then it ran. Great.
No more roaming shock on the bill – that mattered most to me. Stable network throughout Prague, even in the old town.
Amazing how easy this is! On the Tube, on the bus, reception everywhere. Feels like home, just with a better view 😍
Posted stories straight from the sunset in Oia on Santorini. Fast, stable, and I never had to think about data.
Works as described. Good value for money.
Navigated and made calls above the rooftops of Istanbul – zero problems. Activation was faster than expected.
Island hopping along the Croatian coast, a different place every day – and still always online. Booked ferry tickets on the go, video-called the family from the boat. Didn't think it would work this smoothly.
Perfect!! Ready instantly. 10/10 🍀
Relaxed in the thermal baths, then looked up the route to the restaurant right away – network was always there. Didn't need support at all.
Set up quickly and cheaper than roaming. Reconnected briefly once or twice, but nothing major.
Uncomplicated and reliable. Happy to use again.
I'm usually the one who gets annoyed by tech – but this was child's play!! Scan the QR code, boom, online. In Madrid I was out day and night, tapas, flamenco, museums – and my phone just kept up. I'm telling everyone now 🥳
Acropolis, islands, ferries – reception everywhere. As a frequent traveller I appreciate that. Works.
All great, connected instantly.
Good network in the city, a dead spot on the way to Vesuvius – but that was more the area. Overall very satisfied.
Strolled along the Douro and picked out the prettiest cafés on the way. No cable clutter, no SIM fiddling. Just my thing.
Works. Period.
Super handy! Online instantly, no worries 😊
Short trip to Bruges, installed the eSIM the evening before, just got going in the morning. Travelling should always be this stress-free.
Seven days through Stockholm and the archipelago. I recommended the eSIM to my sister after mine worked so well – now we both swear by it. Card payments, navigation, sharing photos: all without a hitch. The fixed price really takes away the guilt about data usage.
Consistently fast network on the Côte d'Azur. Setup without issues. Absolutely fine for the price.
It's easy to get lost in the alleys of Venice – with a stable network and a map, no big deal. Saved me several times.
Pure Andalusia and always online! 🔥 Even at 40 degrees my phone ran better than I did. Absolute recommendation!!
Iceland road trip around the island. I was honestly nervous about the remoteness, but I had reception in the towns and at most stops. Weather and map apps really helped us at the waterfalls. The short dead spot in between was almost relaxing 😄
Fast 5G all the way from Manhattan to Brooklyn. As a USA traveller, exactly what I was looking for. Count me in next time.

FAQ
An eSIM is a digital SIM card already built into your phone. Instead of inserting a plastic card, you simply load it via QR code – ready in seconds, without removing your regular SIM.
Most smartphones from around 2018 support eSIM – e.g. iPhone XR/11 and newer, current Samsung Galaxy and Google Pixel. Check your model in seconds with the Device check.
Right after purchase you receive a QR code by email. Scan it in your settings under “Mobile Data → Add Plan” – done. Best to do this at home before you leave.
As soon as you arrive in Mongolia, the eSIM connects automatically. Beforehand you just enable data roaming for the eSIM once – this doesn't cause any extra costs.
Yes. Your regular SIM stays in your phone – you remain reachable on your number and use the eSIM only for internet. WhatsApp, iMessage & co. keep working as usual.
Unlimited means: you browse for the entire validity period without a data cap – there is no allowance that runs out. As stated in the activation policy, a fair-use rule applies: after 3 GB in a single day you keep browsing at a reduced speed (1 Mbit/s). So you always stay online, nothing is ever switched off – and after 24 hours you get the full 3 GB at full speed again.
Sure. You can share your internet without restriction with your laptop, tablet or travel companions.
Your eSIM connects automatically to the leading local mobile networks in Mongolia – with 4G/5G and nationwide coverage. In very remote areas speeds may vary.
Only once to install the QR code – ideally at home before you leave. After that everything runs automatically, no Wi-Fi needed.
Yes, no problem. Buy your eSIM now – your validity only starts once you activate it. That way everything is sorted before your trip and you start exactly when you want.
Should your eSIM ever not work or not be compatible with your phone, you get your money back – thanks to the 30-day money-back guarantee. And our 24/7 support is always there to help quickly.
