I'm trying really hard to sympathize with you, but I just can't get there. I am on none of the plans you mention, because I never served in the military (and don't serve now), I'm not a First Responder (and never wanted to be) and I'm only 54. At 55, I could get on a 55+ plan, but hey guess what? 55+ plans are optimized for 2 lines. And I have nine lines with T-Mobile. I'd end up paying more.
I value my 2015 Simple Choice plan and because of that I do not chase promos or deals. My monthly price for service has never changed and I've never been screwed out of a promo because I've never been on a promo. In fact, the one time I asked about a promo it was a week after it expired (free line on us). I was initially denied, only for it to appear mysteriously on one of my lines a month later. That line has remained free since 2016.
Promos are dangerous. The terms change all the time and you can get screwed at any time. I'll stick with my 2015 pricing.
