I don't know if anyone needs this info or not, but I figured since you mentioned a Lightning-powered SMS service in the OP, just to let you know, there is an alternative that is up and working, that I have personally used a bunch of times without issue - it's quite good and the prices are very reasonable, it's a great way to verify via SMS for some of those annoying websites which want to require your phone number, and to remain 'anonymous' (or as much as we want to trick ourselves into thinking this). Their website is https://sms4sats.com - costs 3k sats for the basic service, but they have other stuff on there (such as renting a number to use for longer time periods).
