Jackie Tyler owned a mobile phone.
History[[edit] | [edit source]]
During the Battle of Canary Wharf in 2007, the Tenth Doctor borrowed Jackie's phone to contact Rose Tyler through her own mobile phone, which she discretely answered whilst in the presence of the Cult of Skaro. As well as confirming that Rose was alive, this allowed the Doctor to listen to the Daleks, being made aware of the Genesis Ark. Later, Jackie received a phone call from the Doctor and informed him that she had escaped the Cybus Cybermen as well as her location within the Torchwood Tower. (TV: Doomsday)
