The best current phone plans limit high speed hotspot usage to 50 GB per month.  After that it will be 3G speed.  My house uses 20 GB of home internet service per day. 

If you leave the house with your phone, all of your household’s devices lose connection.

Thanks but this new screen has just erased my problem description. And I am so irritated I am not going to waist my time I spend over $4,800 per year for my very large Catholic family. And it time I find a better service. At least for home internet service. Good bye and !!!
