My first non-prepaid plan must have been around 2006-2007, with a slide phone and the very minimum plan I could get which was, IIRC, 50 minutes, unlimited nights and weekends, and exactly zero text messages included, no caller ID nor voicemail 😂 First time I had a data plan was in late 2011, when I got my first smartphone (Galaxy SII), and that was definitely less than 1GB/month…
