Hi @mikeluck81, welcome to the forum and sorry that the app does not show your billing or usage.
Have you checked on the web at BT.com Log in and see if you can see the usage there or get the same error?
Are you using an IOS or Android device?
Try uninstalling and install the app again to see if that resolves the issue.
Cheers
John
Hi, it seems to be the same on the website:
Sorry we couldn't retrieve this data
You owe us £0.00
Hi @mikeluck81, thanks for checking that on the web.
Do you have more than 1 account linked to your BTID? If yes, then you will be able to change to the other account from the drop-down option beside your account number.
Cheers
John
I get the same for all 3 SIMs.
I think I'll have to give them a call.
