Definitely got the tower to yourself! Are you using the T-Mobile gateway included with the service?Two years and 2 months later. Still about as happy as can be with this service. They certainly haven't oversold it in my area. That said, if you're in a crappy area for it, you're going to get crap speeds. Just the nature of the beast.

I wish I had that luck with my connection. Originally I got roughly 750 down and 400 up consistently. I guess my neighbors have jumped onto T-mobile also. I get 400 down and only 20-50 up. I did connect an external waveform antenna to the modem and went into the menu to change to external antenna. Didn't help. I am not disappointed with the download speeds but the upload speeds kill the experience when trying to VPN home or trying to pull camera streams when away.
My RM551 in a M.2 to ethernet sled is still going strong with the $10.00 tablet SIM. Not sure if I had a tower upgrade or not but I'm now getting four times carrier aggregation with four 5G stand alone bands.
I have never used AT&T. Do people use their SIMS in their own devices? With my setup I can do band locking which totally ignores whatever bands you don't want. And, you don't have to mess around with moving the gateway around.That is awesome getting 4 bands connected at once. At one remote location I have, AT&T was the only provider with good speed and they started offering a regular home internet package there ~($60/mo). It is a heavily wooded area otherwise I'd have done starlink instead.
Anyway the AT&T modem that came with their home internet service will only connect to 1 band at a time, and the band it prefers gives about 400 Mbps download with 1 Mbps upload. No typo there. I'm not sure how they even pull this off because I thought more than 1 Mbps upload was required to hit 400 Mbps download over TCP connections, due to all the acknowledgement packets that need to go out. So it is pretty bad for camera remote access. But we figured out if we put the modem on the floor, that reduces the signal strength of its preferred band and it frequently moves to a different band that has ~20 Mbps upload, which is much more usable.
