Good morning @Maciek79, thanks for reaching out to us about this.
Can you please let me know a bit more about what's happening when you try to activate this?
If it's the link you received via text that isn't working, can you please give this a try in a different browser?
Peter
I'm trying to follow this link from BT and this message pops up
Thanks for sharing those details @Maciek79.
If you give our Customer care team a call, they should be able to send off a web form to get this checked out further at our end.
Peter
