Travelling with my TMobile Home Internet device?

I'm hoping to take my box to Alabama for two weeks. I stayed with my relatives for a year and in my room I had an Smart TV everyone else was on cable. I also worked remotely on my computer and my sprint and boost phones were on the T-Mobile network. Needless to say I had no T-Mobile coverage from my phones . I did have to connect to the Wi-Fi to perform most task. It was inferred that I was using up the band with but I know it really was my nephew and his gaming. I kind of got kicked out of the house for that so I want to bring my device just in case I need to work remotely. Being that I had no T-Mobile service I'm hoping that at the box still works. At home I have no T-Mobile service on my phones but that box works like crazy. The speed that I received are nearly triple what was advertised but I've only had the box for three weeks. I still kept my raggedy Spectrm internet but once I determine that the T-Mobile home Internet is reliable I'm going to switch my ring system to the T-Mobile instead of the spectrum Internet. Last month the spectrum lines were cut to disable a ring cameras so I really want to make the switch to the T Mobile Internet to prevent the ring being disabled in this manner again. I'm  gonna cross my fingers that this home Internet box will work in this suburb of Birmingham because I don't want anybody to blame slow speeds from their Internet Wi-Fi on me.
