The main reason for the complete shambles is because 2 mail systems are running in parallel. Under the BTYahoo regime, account management was performed with a 'MYBT' identity which was just a text string and password with no linkage whatsoever with email address. Then, in their infinite wisdom, they introduced the 'BTID' concept with the transfer to BTMail, insisiting that users had a common identity and password with their email address. With the migration to BTMail now stalled, the whole system is in a state of complete limbo with 2 sets of credentials trying to work side by side.
I am not sure how you have been trying to change your BTID but I have used this method. I have shown this with a btinternet.com email address but as you are aware others have said that it can be any email address so you should try it with which ever email address you want but I strongly suspect it has to be a btinternet.com address in order to access all BT services without problem.
Log onto MyBT
Go to My Profile
Go to My Contact Details > Edit
Change email address to your email@example.com
Enter present password for your current BTID
Go to My security details
Click on Password > Edit and change to the same as your firstname.lastname@example.org email password
Enter present password and click save,
Your BTID is now the same as your email@example.com email address and password.
This now how you will log onto MyBT, BTWifi, BT Sport and your firstname.lastname@example.org email.
Utter pillocks, still they continue to come at it from the point of view that it's my fault. Yesterday I had someone get me to download a little prog from citrix that let them use my computer, their demonstration of how to do it was hilarious, type - hit return - get error - delete - type again - hit return - get error, 3 times they tried, 3 times nothing happened. They disapeared for a while then came back to tell me they'd fixed it their end and now I can have my email addy as my BTID user name. Lo and behold, it worked, I can now log in with my old username or my email address on BT.com, not that this matters because I could log in to BT.com anyway.
So, I put my new details into the BTWifi app and surprise surprise, it made no difference, I still can't use BTWifi. I'm given the usual 'get out' clause of "it might take 24 hours" and we end our chat. 24 hours or so later, it still does not work, what a shocker.
Today I got a phone call, I go through as brief an explaination as I think I can get away with, after all, they know the problem now right? Chap on the other end of the line puts me on hold for 3 minutes, comes back and tells me to try to connect now. 'Connect to what?' I ask, 'your laptop to your wifi' he says. My wifi? My chuffing wifi? there's nothing wrong with my wifi, that all works fine, I explained in a cool calm manner.
He disappears for another few minutes, when he comes back he tells me he can't do anything now and can he call back tomorrow? 'Why not?' I say, in fact, why not call me daily to waste my time. I didn't say that bit.
Still smiling, it's only wifi.
I know BT have said that you can log on with your BTID and that it does not need to be a btinternet.com email address but if you have a btinternet.com email address why don't you try changing the BTID to that to see if it will work?
Well, it was worth a try. I changed the email of my account to my btinternet one without any problem. I still can't change my ID name though, I'm not authorised according to the site. The app won't accept that email address as my login either, so still no luck.
I've written to the @BTCare team again, I just have to hope that eventually, my issue will get passed onto someone who can fix it.
Cheers, Neil 😄
