T-mobile Home Internet Wifi Hub loses internet frequently, not reliable.

So, in effect they offload some users to other towers where it is guaranteed the service will be diminished but other users on the close tower remain. It comes down to implementation. One might think that is a win for those that remain on the close tower but in actuality that is probably not the case. The implementation of QoS, quality of service, for those on the tower will undoubtedly lead to reduced bandwidth per user so the service experience will probably not be much better. It always comes down to the return on the investment and pushing to make more money with less expenditure. If not done in a balanced, fair manner it will go sour in the end. I am sure each area will have limitations for tower and cell deployment so they have to decide to deliver a quality experience for the customer or a compromised solution. It might all go like it has for Netflix for them. Users tend to abandon service providers that do not deliver on a quality experience. There is almost always going to be someone else happy and capable to provide the service. 

Here it is rural so limited resources and fortunately they decided to load the tower and, so far, have not overloaded it. It may be only the n71 frequency but it holds stable and the dips in bandwidth when user load picks up has not been a major issue. Our new neighbor could not get on with T-Mobile as all the load for users is determined to be maxed out. They went with Verizon as options here are very limited. The only other option is HughesNet and well I don't consider that much of an option. I hope you find an option that works out for you. If the solution is not stable and reliable users will go elsewhere.
