I've been a beta customer since October 2022, and I ported my main phone number in January. I have never been more happy with a paid service, and I feel the same excitement I did when I first got involved with free open-source software over 16 years ago. The team are super helpful, the service has been great, and the minor bugs I've encountered have often been fixed in hours. You can be confident that this isn't just a marketing stunt: they are definitely beyond beta quality.
Being untethered from traditional phone providers while running FOSS is a dream come true!
