For years I've been using apps like FoxFi and such to use my mobilr hotspot because I don't have access to high speed internet where I live (not even satellite). Starting maybe a month or two ago it's been turning off and on when I turn it on. I turn it on and a few seconds later a message pops up asking me to please wait while verifying, then it turns off. Sometimes it turns off and then turns right back on. Is there anything I can do to get it working properly again without having to pay for it? They wanted to charge an extra $65 a month for it which is why I was using apps.
