Nokia 1100

The Nokia 1100 (and closely related variants, the Nokia 1101 and the Nokia 1108) is a basic GSM mobile phone produced by Nokia. Over 250 million 1100s have been sold since its launch in Q4 2003, making it the world's best selling phone handset and the best selling consumer electronics device in the world at the time. The model was announced on 27 August 2003 and was discontinued in Q1 2010. The 1100 was the last Nokia model to feature monophonic playback of ringtones, after the luxury 8910i, which was discontinued in 2007.

The Nokia 1100 was the company's cheapest mobile phone when it was released to the market. It runs on a stripped-down version of Series 30 with a single soft key and a feature set is similar to the previous 5110/3210/3310 models that were among the most popular mobile phones in the world during their time, before handsets developed several new features such as cameras, polyphonic ringtones and colour screens. The simplicity and low cost made it ideal in developing countries and users who do not require advanced features beyond making calls and SMS text messages, alarm clock, reminders, etc.
