here is the email i just received just to clear things up:
Hello Matthew
Thanks for contacting us about ‘all you can eat’ (AYCE) data and our new price guide.
When we say AYCE data, we truly mean as much data as you can use on your mobile phone. However, there are a couple of changes in the new price plans.
Using your phone as a personal hotspot, is now allowed on all phone price plans and you can use up to 2GB per month as a personal hotspot, or however much data you have, if it’s less than 2GB.
Our SIM Only price plans have just been revised and are now similar to the phone price plans. We no longer have a price plan which includes unlimited personal hotspot.
If you joined or upgraded with us on or before 17th March, you’ll most likely be on one of our older price plans. You can find information about these by visiting:
http://www.three.co.uk/priceguide and choosing the right price guide for when you joined us.
I’ve checked the most recent price guide and the 25GB data limit is only mentioned when you’re using your phone in a ‘Feel at Home’ country. This would be one of the 16 countries where you can use your Three phone and price plan, as if you were still in the UK.
I hope that clears things up, but if you have any other questions about it, you can reply to this email. Or, give me a call at the [removed by mod]. We’re open Monday to Friday, from 9am until 6.30pm.
Thanks again
