The Nokia 1100, and the closely-related variant the Nokia 1101, is a durable and very simple GSM mobile phone produced by Nokia with a 96 x 65 monochrome screen. It is targeted towards developing countries and users who do not require advanced features beyond making calls and SMS text messages, alarm clock, reminders, etc. The 1100 is similar to the now discontinued 5110/3210/3310 models that were among the most popular cell phones in the world a few years ago before handsets developed several new features such as cameras, polyphonic ringtones and colour screens.
