Hagenuk MT-2000

[1] The device was designed and manufactured by Hagenuk's development centre in Støvring, Denmark.

It was believed until recently that it was the first smartphone to have installed a video game but then it turned out that it was the third one – the first two were Siemens S1 (hidden Tetris – called "Klotz" here[3]) and the IBM Simon (Scramble) – both built in 1993 and released in 1994.

There were two variants of the phone produced – with and without dedicated physical buttons for volume up and down and power on/off.

The phones were at the beginning sold in two variants, in both the name of Hagenuk and Cetelco.

Their first GSM mobile, the MT-900, got it official type approval only 4 weeks after Nokia got type approval for their first GSM hand portable (the 1011) but Hagenuk beat Nokia by three years in getting a game of Tetris.
