The app is clean and minimal

The app is clean and minimal, which I really appreciated. I could see my remaining data instantly without digging through menus. Used it daily around Lisbon and the UI never confused me.

Easy and simple activation

I bought the eSIM while boarding my flight to Barcelona. Setup took under 3 minutes and my plan activated once I landed at BCN. No QR-code, no APN. I was online before baggage claim which was exactly what I needed after a 6am flight

I decided to try this eSIM for my trip to Germany, but I didn't know that you need to set it up before the flight. When I arrived, I found free Wi-Fi and contacted support. They helped me with setup in less than 10 minutes! Very simple and useful thing for travel and awesome support!

Good eSIM for New Zealand

I used this eSIM in New Zealand and, since I'm not really a tech person, I was worried I might do something wrong, but TooSIM app was so simple I finished setting it up in 5 minutes. I also was impressed by their speeds. Not a single slow down during my 30 day trip. And I didn't even need to activate it myself, it started working when I stepped off the plane.

Cheap and fast eSIM

Great price for Europe and fine speed in Belgium. eSIM switches itself at the border. 5G everywhere, no signal drops. I'll continue using this app!

I really appreciate how straightforward…

I really appreciate how straightforward the app is to navigate. Setting up the eSIM is quick and effortless, and the step by the guide is extremely clear. The pricing is reasonable and whenever you need assistance, customer support is easy to reach and very responsive.

Great usage while working overseas

While working overseas, several friends recommended TooSim, so I downloaded the app.

It was exactly as they described, offering different packages with data, calls, or both, all at good prices and very reliable. I'll definitely use it again!
