I have a "dumbphone".... Samsung T199.
I've had it for 7 years, that is, since I retired.
Before that I had..... nothing. Really, no smart phone, Cricket phone, Star Trek flip phone, nada.
I pay $5 per month for 30 minutes of talk time (no texting, no camera, certainly no web access).
30 minutes is enough time to call a tow truck and give him my location.
I have a phone at home for everything else, and it is (wait for it)... a LL (Cue the Luddite chorus).
Anyway, the carrier is T-mobile.
So my question is: why does my phone still work with the new 5G.... thing? I can still make calls.
(As you can see I am totally ignorant of this particular "tech").
Can someone explain this to me in short sentences and using one syllable words?
