Why do iPhone 14 models act differently in old Sprint areas?

I was just in Sarasota, FL where TMO is heavily using Sprint frequencies. I've noticed that even in line of site conditions, my iPhone 14 Pro Max connects via LTE on band 41 then switches to (usually) band 2. During this period, the iPhone has slow/no connectivity. Sometimes the phone never connects to 5G. 

 

In my home area - MetroWest MA, the device initially connect on band 66 and, lately, has been switching to band 71. It never stays in LTE mode - at least perceptively. 
 

No settings were changed between the two locations. 
 

Asking the clowns who call themselves "experts" in customer support will yield no useful info. I'm hoping an RF geek here might educate me a little on how TMO's network works.

    Different areas have different coverage both by band and actual buildout.  Sprint is/was LTE  B25/B26/B41, TMobile 'was' B2/B66 (b4)/B12/B71, and n71 5g.  Where TMobile has completed its rebuild of Sprint, it will have B41/n41 and possibly n25. 

    Tmobile users typically can roam on Sprint.

     

  • also youre for sure positive the tower you were in “eye of sight” with is an actual Sprint/Tmo tower?
