Landing day, two ways.
Same flight. Same jet lag. Very different first hour.
Option A
The airport SIM shuffle
- Queue at a kiosk that shut twenty minutes before you landed.
- Hand your passport to a stranger for a photocopy.
- Poke out your home SIM with an earring and lose it in a hotel drawer.
- Pay in local cash you haven't withdrawn yet.
- Or skip it, switch on roaming, and get a €340 bill in three weeks.
Option B
The Simba way
- Buy tonight, on the sofa, in about a minute.
- One QR code lands in your inbox. Scan it once, done.
- Your home number stays in your phone. Calls and texts keep arriving.
- Fixed price in your own currency, paid before you leave.
- Wheels down, airplane mode off, maps already loading.
Small print, but the good kind.

Your number stays yours
The eSIM adds data. Your home line keeps taking calls, texts, and two-factor codes.
Hotspot included
Share with a laptop, a tablet, or the friend who said they'd sort it at the airport.

“Installed it at the gate in Heathrow because I'd forgotten. Had signal in Bangkok before the seatbelt sign went off. Slightly annoyed at how easy that was.”
“Three of us in Italy for two weeks. One Explorer plan, hotspot on, €11.90 total. My old roaming pass was €12 a day. A day.”
“I work remotely from a new country every month, so I've tried all of these. This is the only one where the top-up didn't make me re-install anything.”
Croatia eSIM questions.
Which networks does the Croatia eSIM use?
Simba connects to 3 networks in Croatia and switches between them automatically, so you are on whichever signal is strongest where you are standing. 5G is included wherever the local network runs it, at no extra cost.
How much data do I need for Croatia?
Most travellers use around 5 GB on a ten-day trip — maps, messaging, a few hours of scrolling and a nightly video call. That is the Explorer plan. If you mostly use hotel Wi-Fi and just want maps and boarding passes, the 1 GB Cub plan at $4.10 is plenty.
Will this work on my phone?
If your phone was bought unlocked in the last few years, almost certainly. That covers iPhone XS and newer, Pixel 3 and newer, Samsung S20 and newer, and 200+ other models. Two catches: phones locked to a carrier cannot add an eSIM, and a handful of models sold in mainland China ship without eSIM hardware. Check yours in Settings before you buy — if it will not install, we refund in full.
When does my data start counting?
When you first connect to a network at your destination, not when you pay. So you can buy weeks early and install it at home in peace. The clock starts on arrival.
Do I keep my own number?
Yes. The eSIM sits next to your normal SIM and only handles data. Your usual number still rings, still gets texts, and still receives bank codes.
WhatsApp, iMessage, and Signal keep working on your existing account — they run over data, so they are unaffected by the switch.
What if I run out of data mid-trip?
Top up from the same eSIM in a few taps — nothing to re-install and no new QR code. We also message you at 80% used, so it rarely comes as a surprise.
Can I call and text on the eSIM?
These are data plans, so no local voice minutes or SMS on the eSIM itself. In practice that is fine: WhatsApp, FaceTime, and Signal calls all run over data, and your home number still handles anything that needs a real phone line.
Which countries are covered?
190+, from Japan to Peru to Tanzania. Multi-country trips are easier on a regional plan — one Europe plan covers 39 countries, and the Global plan covers 130. Search your destination in the box at the top of the page to see live pricing.
What's the catch on refunds?
Not much of one. If the eSIM will not install or you never connect to a network, you get a full refund, no questions. Once data has been used we can refund the unused portion within 30 days.
