This link https://www.bt.com/help/landline/set-up-and-use-bt-text appears to say the text message to a landline will be delivered as a synthetic voice message
It also says 'We have contacted all users of the text service to inform them of the upcoming changes and will support them in finding alternative solutions with our partners if needed' well all I can say is they never contacted me as I was completely unaware BT had deleted this service.
I rather suspect as a mere home customer, one of those people that pays BT for a service, they decided I didn't count.
Poor form BT.
FWIW other suppliers of landline services seem to be going down the same 'deliver as synthetic voice' route. I know not is they actually warned their customers as BT didn't.
