That looks simple, but it doesn't show the surface mount chip (or chips) on the other side of the board!.

well... it doesnt have any chips!! the backside of the circuit is empty! this is, indeed a very simple device! and very handfull

I didn't realise it was so crude, it sounds like you have to take your phone to pieces and solder wires across it's keypad!.

well... yes! its a bit crude, but it only needs to solder to some number of the keypad! to make a speed-dial... soldering two wires to some cheap spare cellphone is easy!
