Motorola
D520

The Motorola D520 (Type: MG2-4B11) was a GSM phone launched in 1998. Several variants of this design were manufactured including the Motorola C520 and Motorola Colorado.  It was one of the first Motorola mobile phones to use a smaller size SIM card which resulted in it being reasonably slim with a curved body shape which made it comfortable to hold. By choosing a slightly thicker back cover, the mobile could be converted to use four AA batteries. The screen could display 2 lines of 12 characters with additional fixed icons for signal strength and battery charge levels. An address book could store up to 90 telephone numbers with associated names within the phone's memory with speed dial access. A range of call timers recorded the combined duration of all calls, the duration of the most recent call and a programmable audible call alert timer which operated during a call. The call log recorded the last 10 telephone numbers dialled and also received. There was a choice of 11 ring tones and the mobile could both send and receive SMS text messages.
