Is my neighbor's 4G LTE Cellspot degrading my service?
For reference I live in an apartment building which has acceptable T-Mobile service as I've gone years without any issues living here. A new neighbor has moved in recently, and I noticed that I have been experiencing worse call quality and more calls have been dropping. Our building has a very spotty internet provider with high ping and slow upload speeds. A few things lead me to believe that my new neighbors have installed a T-Mobile 4G LTE Cellspot. I'm familiar with the Cellspot because my parents live in a rural area and have one in their home. In the past my phone used to display 5G service regularly, now instead it displays LTE exclusively. When stepping outside about twenty yards away from the building my 5G service returns. I also receive better speeds when running a speed test outside away from my building. Inside of my building I barely reach 40 mbs down and usually below 5 mbs upload speed which is important for calls and video calls. Speed and the quality of calls has never been an issue before. But only recently because of this I’m needing to leave my home to make calls. It's frustrating because like I said this is a recent issue and I can pin it to something that's making it worse. I use my T-Mobile service to get away from my terrible internet to begin with. I understand that there is no way to connect to the tower directly because the Cellspot is basically a small tower itself and the phone connects there by default. What are my options?
