Tried all that, still no joy

Hi ​@Lleuadwen,

We're sorry to hear you're having trouble making calls to landline numbers.

If you're able to call mobile numbers but receive a "Call Failed" message when calling landlines, it may be that the landline numbers you're calling are classed as out-of-plan chargeable numbers. In this case, you'll need to make sure your bill cap is set high enough to allow the call to connect.

To check or change your bill cap:

• Log in to the iD Mobile app or your online account.
• Go to Bills.
• Select Manage Bill Cap.
• Increase it to a suitable amount if required.

If your bill cap is already high enough and you're still experiencing the issue, please let us know and we'll be happy to help you investigate further.

Regards,
