“ Our company is engaged in the supply of food to Russia. Thanks to our familiarity with SIP.SIM, our communication costs have been reduced by an order of magnitude. We transferred all the managers of the direction of Russia on their rates. The quality of communication is amazing. Incoming calls work stably. Customers are very satisfied! ”

“ Thanks to SIP.SIM, I found a really profitable and reliable connection. I can instantly reach out to old men in the outback, where the phone still somehow takes, and there is no Internet at all. We chat for hours on end. I'm happy :)) ”

“ SIP.SIM is a reliable partner! Personal manager is fantastic, all questions are solved in real time. Connected instantly. Communication is beyond praise. Counterparts without any problems dial the personal Russian mobile number given to me. With payment, too, no problems. I put honest 5 stars! ”

“ I use the connection from SIP.SIM and to communicate with relatives, and they are people of the age, they are hard on new technologies like smartphones. And for business issues, because I am engaged in design, I have to communicate with clients a lot, and it’s not enough that it's not convenient to catch everyone in messengers, it’s also not solid. And then I call from the Russian number and receive calls to him, as if I am in Russia, and at the same time I can be in Tae, at least in Prague. Thanks for the service! ”
