Bit of a heads up for those that use a Premier Inn. 1 am this morning I receive an email thanking me for purchasing 24 hours of WiFi via Virgin WiFi at Premier Inn. Naturally I think its spam and start checking the email for legit-ness to find it its all kosher.

Rings the number on the email (after checking it out) to find out what is going on, I'm at home, not in a Premier Inn, little bit worried, gives the woman my email address and she asks if I've sold any devices/had anything stolen recently. Tracks my email down to a place in the Midlands that is when it all clicks in, sold a device quite a while ago.

What it would appear is that is caches the email address you use and if someone else buys WiFi and pays for it you still get an email, you have to phone up and get the device manually swapped to the other persons address, they cannot just delete it.

Not a bit of a flaw in the system I'd say but wanted to give you a heads up on here. Most of the time I use my MiFi but I had used that previous device when 4G wasn't too good.

Good point! this could actually apply with quite a few things as well possibly, I know a lot of free wifi networks can save your mac address so you dont need to register/join again and they dont say how long the mac remains in the system.
