Philips
Diga

The Philips Diga (TCD308) was introduced in 1997. It had a removable slider that protected the majority of the keyboard but did not cover the top two rows of keys, thereby allowing calls to be answered and made from the phone book without moving the slider. The monochrome screen could display a single line of text with additional fixed icons. The phone book comprised of a name list that stored telephone numbers and associated names within the SIM card. The main keypad keys 1 to 9 could be configured as hot keys. Specific functions were activated by holding one of the keys down. For example, key 1 could call the answer phone, a key could be defined as a flash dial key for a name list entry, another could turn the ringer off, another could redial the last called number and so on. In total there were 21 functions that could be assigned to a hot key. The call register logged the last 10 dialled calls and the last 10 received calls including both answered and missed calls. Call timers recorded the duration of the most recent call together with a cumulative total. There was a choice of 8 different ring tones and the Philips Diga was able to both send and receive SMS text messages. The Mobile Phone Museum also has a Cellnet-branded variant of this device.
