My son added 2 more people on our plan & then my hotspot stopped working. It was right in the middle of our plan. I have talked to customer service but never got a real answers why. There has to be some kind of glitch. All he kept saying is my hotspot was over. It was working find until the 2 people were added onto the plan. Plus since the 2 people were added on my internet is slow & freezes up all the time!
