a question about voip.ms

Hi friends!
So I did it. I signed up for a voip.ms account and downloaded bria solo to my mac so I can get myself an extra number. Now, about how to actually do it.
Do I need to pay for each number I want separately? If so, depending on how often I find it necessary to change my number, this could get expensive quickly. I suppose I could look through the voip.ms site and find this answer, but their page has a lot of info and sifting through it all with my screen reader is sometimes more time consuming than just posting here and hoping someone has experience. :slight_smile:
Thanks in advance!
