It is not expensive. Anyone can afford it. It all depends on your desire. You can buy it for yourself if you want. I have my personal number that I chose. I am very pleased because I received a beautiful room, quality services at a low price. I changed my number from callhippo.com on number from https://hottelecom.biz/sip-numbers.html . This is the best phone company. I advise you to contact them.
It is already difficult to imagine a modern person without a mobile phone. On the street, in transport, we constantly listen to someone's conversations, sometimes lasting for hours. Already in the world there are about five billion mobile subscribers.
