Reviews
Taylor Gallagher
Activated the eSIM while still in the airport and got online almost instantly. Ordered a taxi and contacted my hotel without searching for WiFi.
Mykyta Skrypets
Works smoothly, no issues so far. Stable, fast and does what it promises. Have a detailed guide that really helps. Super easy to follow
Nanangtisna
The app itself is very convenient. I liked being able to manage everything from one place without scanning QR codes
Ali Shakir Mahmood
The most flexible data plans. Highly recommend using the calculator on their site. It allows complete freedom over your holiday internet data budget. Never overpaying for data again! ✨ Highly satisfied with service.
Egor
Great internet speed abroad. Streaming videos and using maps worked perfectly. Speed was surprisingly good in most places.
Benny Osafo
No confusing conditions or hidden payments. Everything is straightforward.
Matias Fernandez
Thought it might be tricky, but it was actually super easy. Got online in minutes and didn’t think about it again.
Matthew Scott
Only needed internet for a few days and didn’t want any long-term plans. What I liked is that you can just choose exactly how many days and how much data you need with their calculator. No fixed packages, no overpaying for extra GB you won’t use. And if you run out, you can always top up. Super flexible.
Just open the app, set it up, and forget about connection issues.
Manage everything from one app: buy a plan, activate your eSIM in a couple of taps, pause it between trips, and top up on the go. Check your data balance, switch plans, and keep your eSIMs available even offline — no settings to dig through, no instructions to read.
