To celebrate the upcoming series Doctor Who staring Jodie Whittaker, I'm attempting to chronicle all the mobile phones used in previous shows.
If you think you've spotted something that's not listed here, or think I've made a mistake, drop it in the comments.
You can follow along with all 10 series.
Before the Flood
Not until episode 4 do we get a new phone for Clara.
Nice clear shot of the iPhone 4S. A phone first released in 2011, although the episode was shot in 2015. Perhaps Clara is now on an economy drive after splashing out on shiny new phones for so long. Unusually for Doctor Who the phone is a central MacGuffin in this story.
The Zygon Invasion - Osgood
Osgood takes shelter from the terrifying alien menace and places a desperate call to the TARDIS.
The prop team have helpfully stuck some black tape over the manufacturers name, but we get a clearer shot a moment later.
Regular readers will recognise this as the exact same phone Clara used last season in Mummy on the Orient Express.
Headcannon! Clara regifted her phone to Osgood as a Christmas present prior to the Christmas special.
The Zygon Invasion - The Doctor
A rare occurrence. The Doctor actually handling a mobile phone.
Not quite enough detail just from the camera to tell what it is. Patience, young grasshopper.
The Zygon Invasion - Kate
The Brigadier's daughter and successor has a heavily armoured phone in her possession.
Beneath all the casing we can see the iPhone 5.
The Zygon Inversion - The Doctor
Finally a shot of the front of the Doctor's phone.
More black sticky tape, but still quite recognisable as the Galaxy S II Plus. The same phone as the Elf used in Last Christmas. Perhaps a thank you pressie for the Time Lord from Santa?
Face the Raven - Rigsy
Rigsy from episode 9 of last season urgently calls the Doctor for assistance when an ominous tattoo suddenly appears on the back of his neck.
Another anonymous black rectangle.
We can just about make out the Microsoft logo. Based on the camera bump, this is the Microsoft Lumia 535. Very exciting, this is the first Windows Phone on Doctor Who!
Goodbye impossible girl
So that wraps things up for the Doctor and Clara partnership. A great shame as she had impeccable taste in phones.
