Just moved into a new apartment and we don't have WiFi yet, so I used my phone. I had 6 GB and used all that up, then that 'datastash' afterwards, and now I've still got internet but it's running slower now (as I was warned). I know there's a $15 charge for using the hotspot but are there any additional charges when you still continue to use the hotspot, even when it's running slow? My phone now says 7.5 GB/6 GB.
