Fantastica soluzione per chi viaggia!
Io sto facendo il giro del mondo a piedi e grazie a
Chatsim resto in contatto con tutti con un costo irrisorio.

It saves me a lot of money on mobile data for my exchange! It comes especially handy when I travel around that I don't have to buy a new simcard or data plan. Save the trouble of even searching about the price and plan of each country i visit. The connection is stable and reasonably fast. I was recommended by a friend who works in aviation and I would definitely recommend it to others.
Hace ya un año que disfruto del servicio de ChatSim. Cuando viaje al exterior me resulto de mucha utilidad!
Très pratique pour voyager. Nous permet de rester en contact avec nos amis et notre famille. Assez facile à utiliser. Un must avec des ados branchés.

I'm a frequent flyer and I have used chatsim in at least 10 different countries and it works! I have a dual sim card phone which makes chatsim even more perfect. Keeps me in touch with my loved ones back home and I absolutely just love it! Thumbs up!
