I've been chasing T-Mobile's signal at my location for the last 15 years. They actually just finally co-located on the main tower in town so now I have a decent signal. Try going to Cellmapper and it will give you good information on what towers are near you provided they have been mapped. That being said, I used their home internet for a few years at another location with decent results. I didn't have an unlimited plan or anything but the router I ended up using was an expensive Huawei unit which I needed for band 12 access at the time, probably 6-7 years ago or so. I still have the equipment but got rid of the service because the plan options were not unlimited and did not fit my budget. I initially used a hotspot which I disliked but it worked well enough for monitoring the thermostat I have.
I also have quite a bit of experience chasing Clear internet's Wimax signal which became the band 41 that you want to be locked onto. The router I had at the time had an external antenna port. I ended up purchasing a yagi style antenna for it. 2500mhz band is inherently difficult at further distances. I haven't been following T-mobile's home internet equipment but I would see if they have a router with an external antenna port and then point an antenna at the tower you want.
Before I had service in my area I purchased a Wilson cell signal booster which I still have. I was able to have usable data inside my house using it. The tower was far away and had band 12. Usually couldn't get a signal lock in my driveway with my cellphone but with the booster on my rooftop I was able to get probably 2 bars inside my house.
