We have put together a short survey to capture your feedback in terms of what BT can do when you experience home Wi-Fi issues. We would appreciate it if you could take a couple of minutes to complete a short survey. Read more from here, Fix my home Wi-Fi
I notice in the speed dal numbers of my BT premium it adds the number but it won't let you add the person it belongs to, this is a bit of a nuisance I think, I wish landlines could update via Bluetooth if the phone has it
Try the syncronisation of contact with device. If you do so then your personal contacts will appear on the speed dials of your device.
I syncronised the contacts from my iPhone but none of the contacts went into my speed dial they all went to my contacts list and when I tried to add a contact from the options in speed dial it said I have no contacts so whether it only adds contacts you place by hand in the speed dial list via the options I don't know!
