This was a version of tamagotchi released only in Japan. It has the special ability of connecting to cell phones. The owner of the cell phone has to download a tamagotchi game onto their cell phone. The Keitai has an aerial used for connecting to the cell phones. When connecting to the cell phone, the tamagotchi goes to the phone and on it can visit its parents, play games, or get married. It can also collect food from each region of Japan through ten-digit passwords generated by the phone. It is able to connect through infra red to the tamagotchi plus and the Deka tamagotchi. Below is a growth chart displaying all the possible characters. It is possible to get a special character by letting your tamagotchi grow old without mating it then mating it to another old tamagotchi. The offspring will evolve straight from a baby to the special character. This special character was included in most later versions such as the Entama, Uratama, Versions 1, 2, 3, 4, and 4.5.
The Keitai has three games to play. The first one is Get
's. In this game you have to use the A and C buttons to move to the left and right of the screen so as to catch the 's and avoid the's. This game was reused in the version 3.
The next game is a basketball game where you have to shoot hoops. The third is a racing game where you have to bet on whether your tamagotchi will get first, second, or third place. If you bet on first and win you get thirty points, if you bet on second and win you get 20, and if you bet on third and win you get 10.
