If you're reading this thread and wondering how to get started with a double edged safety razor, try this starter kit from Maggard. I wanted to try it for years but never knew where to start. I've solely been using this kit for about a year.

I'm on an MVNO that uses AT&T service, Redpocket. I had a phone (LG G8) that WAS on the whitelist and AT&T dissabled it after the 3G shutdown. I was without service for over a month until I gave up and bought a newer phone. Customer service had no clue what to do.
