My BIL has switched to T-mobile Home. Streaming seemed OK over Tgiving.  T-mobile cell works in his urban area but failed when he visited here in the hinterlands.

I can't comment about T-Mobile Home broadband, but a neighbor has Verizon 5G Home and loves it.  He quit Comcast.

I have been very tempted to make the switch. Need to find some people locally to see what their experience with it is.
