way to see if my tower near me is 5G

Another good resource is the app opensignal. Good for testing speeds on ur phone or wifi, looking at tower locations, etc. Now I just need an antenna

Using Cellmapper.net and the CGI information from your phone (or, in my case) the T-Mobile Home Internet app, you should be able to find the T-Mobile tower that you're connected to.  But keep in mind that the Cellmapper app is not necessarily up to date.  Along the lines of your complaint, I recently observed a pleasant increase in my download/upload speed.  Investigation found that T-Mobile had evidently placed a 5G installation about 2 miles from my location and speeds were wonderful (this location did not show up on Cellmapper but I found the installation via RF direction finding equipment that I have). All was great for about a couple of weeks, but now the 5G signal is gone and the previous throughput from the LTE tower that I was connected to for a year went from an average of 15Mbps to less about 2MBps.  Since I'm in a rural location, the problem is probably an oversubscription of users on the 5Mb bandwidth of the LTE link.  So, unless T-Mobile reactivates their 5G, I'll be forced to migrate to another carrier, most likely to Starlink, where throughput speeds (so far) are much better than the regression in performance from T-Mobile.

How exactly do you know what tower you are connected in the TMO app?

In Sussex county New Jersey the 5 g is out.

There is no 4g or4 g LTE either right now.

When will TMobile be supplying 5g again?

I hope before the snow and ice comes.
