I went to the local Boost Mobile store to see if I can get a new SIM card and it looked abandoned. The doors were locked; there was no Closed sign out. They're supposed to be open today, and even if they close early 3:30 seems ridiculous.
When I got home I called Boost. There were no paths thru the phone menu to get to a real person, so I just started pressing '0'. Some times that works, and sometimes the robot just hangs up on you. This time it connected me to a sales tech or something. I asked about getting a new SIM card and she said my phone is not compatible with their Enhanced Network. I said, "Are you sure about that? It should be compatible but will only connect at 4G instead of 5G." She said if I'm happy with my existing service nothing will change in January. (that's when they shut down all their 3G towers.)
I am skeptical. But if I lose my cell service for a few days in January, it won't be the end of the world like it would be if I was a Millennial. I'm a Boomer so I sometimes go for *days* without looking at my phone.
