H Logging in to Wifi hotspots

• There are two versions of Openzone access as supplied with BT Broadband option 3 / BT Total Broadband
  1) Early version is by voucher. This was a numeric id plus password and could be used at any BTOpenzone site or any BTOpenzone partners. It was limited to 250 minutes per month.
  2) Later (FON based) version uses your primary BTBroadband email address and password and is ONLY available at FON points and BTOpenzone sites, NOT Partners!!  Openzone sites are restricted by a fair use policy. (500 minutes?)
• Caffe Nero are Openzone sites
• Cloud are apparently BTOpenzone partners. Can anyone confirm or refute please.
• McDonalds also allow free login by anyone and is nothing to do with BT or Openzone. It uses the CLOUD network but log in via the McDonalds access & save your Openzone minute allowance
• A FON point that is running on a BT Homehub has a very limited range and all you have to locate it is the postcode. It will be very hard to find and log onto it. My wifi will not reach to the road outside my house, never mind any of the other houses with the same postcode. BTFON connections are free.
• You can also log into ANY wifi point that you are given the SSID and WEP/WPA key for. 

Wherever you are ALWAYS check if there is a free option as the BTOpenzone is limited to 500 minutes
