Thank you for replying, markp.
When I look at your product description, and the details of the package I am purchasing, they say "unlimited wifi" and "unlimited Openzone minutes" respectively. No qualification, and certainly no "single user" restriction.
Surely this is not another case of BT's marketing being lax with accuracy ? I would describe this as misleading at best. Please can you point me towards a statement to justify the interpretation of "unlimited wifi" that you have given in your answer above, because what you have described I would consider to be "extremely limited wifi".
My security concerns stem from having to use the main email address and password for the account in order to access BT wifi in the first place. That is the bit that I find troubling, especially given how easy it is to "fake" a wifi hotspot in order to harvest information. That's the aspect I would like BT to comment on...or better still, to offer an alternative that is inherently less risky.
Thank you,
John
