Great read, this spiraled me down a rabbit hole of research, posting it here in case someone has the same questions:

How phone numbers / phones work: https://www.youtube.com/watch?v=FZsajM6M3UY

How to buy a block of phone numbers: https://www.siptrunk.com/2015/12/how-to-find-did-number-bloc...

I'm trying to do a thought exercise on how I might approach building a Twilio side project, but after I buy phone numbers from sipTrunk, I wouldn't know how to connect it to sim cards.
