Milwaukee is a market where T-Mobile lacks current low-band (< 1GHz) licenses. Which is a good reason for having poor indoor service. (Particularly considering the amount of insulation buildings need in Milwaukee.) T-Mobile will be deploying new 600 MHz signals over the next few years but this will require new (currently unavailable) phones to use.
I worked for many years in a building where I was not allowed to use a cell phone and there was, in any event, no T-Mobile signal. I just forwarded my incoming calls to my desk phone and took my calls that way. Of course, I had a personal, un-shared desk phone. I also live in an area where T-Mobile has no low-band service. I find that I must frequently connect to a store's WiFi signal to continue to have service inside. I also keep an old PagePlus PAYG flip phone active for about $32/year and sometimes conditionally forward calls to that phone when traveling where I might be in and out of T-Mobile service.
If none of these are viable options for you and depending on how you purchased your "$600 paperweight" you may be able to unlock your phone, port out of your T-Mobile service to a compatible carrier (e.g. AT&T) and continue making just the phone payments to T-Mobile.
