The Nokia 1011 (NHE-2X5, NHE-2XN) is the first mass-produced GSM phone. It was sold also as Mobira Cityman 2000. The typenumber refers to the launch date, 10 November 1992.
The black handset measured 195 x 60 x 45 mm and featured a monochrome LCD and an extendable antenna. The memory could hold 99 phone numbers. It did not yet employ Nokia's characteristic ringtone: that was only introduced in 1994. The phone operated in the 900 MHz GSM band. At that time the device cost about 2500 DM (about euros today).
The phone was able to receive SMS messages but not send them.
Nokia 1011 continued production until 1994, when Nokia 2010 and Nokia 2110 were introduced as successors.
Today Nokia 1011 can be found in museum collections, and it is considered to be one of the rarest Nokia phones to find.
