I've got Do more unlimited and I'm having some issues with mobile hotspot. I do a speed test on my tablet and get good speeds for about 5-10 seconds, then it drops off completely. I use it for a tablet for work, and when I try to download an app, it gets to 80-90% and stops. I then try to watch a youtube video, it get about 10-15 seconds in, and starts buffering. I have do more unlimited and I'm only 1gb into the 15. So it shouldn't be throttling. I should have full speed.
