Changing between primary and secondary lines for SMS - IPhone Xr
Am having iPhone Xr and actually facing a problem in the SMS section when i want to change between the 2 lines am having while sending a message in an existing chat.
So for example when am sending messages to a specific contact using my primary line and then i want to change it to the secondary line to same contact , when i click the name of sender and then info, i find "Using primary for this conversation" which is not changeable by any means !
Having the option to swap between primary and secondary lines to send message from is only available while sending new message to a new contact who i don't have any previous conversation with.
Thanks
