I use an EE 4G SIM card to create a broadband linked WiFi network in my house.
It basically works well - but my data allowance is being eaten up by repeated 50Mb usages - some just two or three minutes apart. I'm sure that this isn't email / web browsing - but neither I nor EE know what it is for.
Has anyone else found the same issue? Any thoughts / clues? Any likely culprits. Apple Photostream or Dropbox could be part of the problem - but that is just a hunch.
Any responses appreciated.
