I have just bought a panasonic dect KX-GT8522E.
I have fully charged, registered and received the set-up text from BT, biut I cannot send a text message
Ring Customer services free on your mobile to your supplier ( BT? ) and ask them to help you, as could be a network problem....if not, go back to the shop you purchased it from OR ring them in the morning and ask them to help you, carless......
