do I have to wait for my bt service to go live before I can crate a account
Welcome to this user forum for BT Retail phone and broadband customers.
You can do it now.
Start here https://my.bt.com/s/apps/appsconnectedcare/index.html#/createbtoneid
That link doesn’t work
It works here. Can you try it on a different device?
Make sure that you are not running any form of VPN or blocking software.
Your BT ID has to be an email address.
