Reisende, in ihren eigenen Worten.

Very happy with the performance and simplicity. Tried the others and best by far.

Wir haben schon einige E SIM fürs Ausland gehabt aber One Sim ist das beste was uns passieren konnte. Top Service. Hammer leichte Installation. Bei Fragen steht der Kundenservice über WhatsApp sofort zur Verfügung. Sehr gutes Preisleistungs Angebot.

Sehr gute Internetverbindung im Ausland. Die Aktivierung war einfach und das Internet hat zuverlässig funktioniert. Ich bin sehr zufrieden und kann One Sim weiterempfehlen.

Used it for a week in Malta, it worked superbly. Not a single complaint!

Jedes Land wo drauf ist sehr gut funktioniert

Hab es für 2 Wochen im Kosovo benutzt. Es war sehr gut und einfach zu benutzen.

Bin in der Türkei kann ich nur empfehlen

It is an amazing esim provider. I have used it during my trip in the Balkans and it worked amazingly. Very easy to set up and had a fast and stable connection throught the whole trip. Definitely worth the 5 star review.

Hab erst jetst gefunden, hab das benutzt ab Deutschland bis Mazedonien und úberall gibt es signale. Sehr gutes preis und gutes Qualität! Empfehle ich gerne weiter!

Super user friendly, works literally everywhere and the best prices compared to other options in the market.

The app downloaded and set up perfectly. No errors while i was in germany.

I dont think i will ever change this esim again, its the best.

Besuche jedes Jahr meine Familie im Balkan, und onesim ist echt Gold wert. eSIM schon vor der Landung startklar, Aufladen geht in Sekunden, und viel billiger als Roaming. Sehr zu empfehlen!

App was great, really easy to use.

Excellent service. Easy to set up, reliable internet connection, and great coverage. The 24/7 customer support is very helpful and responsive. Everything worked perfectly. Highly recommended.

No words needed, works amazing! I highly recommend.

Super fast internet, very easy set-up.

I had a very good experience with onesim. Activation was fast and simple, and the internet worked without problems the whole time.

Works great. One eSIM for the whole world, easy package purchases, and reliable internet wherever I travel.

The setup was incredibly simple and I was connected the moment I arrived. The service was smooth, pricing was fair and everything worked exactly as promised.

Reliable and very easy to use, having a single esim is a life saver.

I traveled from Kosovo to Tirana (Albania) and then to Barcelona (Spain). During the drive through Albania, we had no problems with the internet, which was covered by the Vodafone network. The connection was stable. When we arrived in Barcelona, it automatically connected to the internet right after landing. … Overall, everything worked very well, and I had a great experience using this app.

One of the best esim apps I have ever used and believe me I have used too many. The fact that you only install the esim once and refill it for every destination is a lifesaver.

App works great and the idea of having only one esim and just refilling it makes it very easy to use.

A very good app, easy to use, and the internet works every moment.

Easy to use and very nice prices. Overall great experience.

Convenient, easy, and fast. Just used it in my last travel to Switzerland and it worked perfectly. The best thing, I will never need another SIM card!

Great app, easy to use and great service.

Compared to other eSIM, the UI is very user friendly!
