Been wanting to integrate SMS authentication for a while... read a lot
about SMS gateways in linux/rpi, but finding an actual modem that
supports SMS with US carriers has been the harder part, and really
didn't want to pay what could be larger fees to Twilio for logins.

works, will update if it does. Looks like tello has a $5/mo plan w/ no
data, 100 minutes (won't be using) and free texts.

Apparently, needed a different modem for US use...
