The Nokia E52 and Nokia E55 are mobile phones from Nokia's business-oriented Eseries range. They run Symbian OS v9.3 (S60 3rd Edition FP1). The E55 was announced on 16 February 2009, whilst the E52 was announced later on 6 May 2009. They are both physically and functionally identical, except that the E55 has a 'half-QWERTY' keyboard, similar to the SureType keyboard on BlackBerry Pearl, whereas the E52 revision has a traditional T9 keypad.^[5]

They are available in Black, Black Aluminum, Metal Grey aluminium, White Aluminium and Gold. They came with a 1 GB microSD memory card,^[6] but it supports microSD cards with up to 32 GB memory. It also has 60 MB free user memory. The E52 is the successor to Nokia's successful E51 model.^[7] Latest firmware version is v091.004 released on June 2, 2012.

The E52 and E55 were, at 9.9 mm thickness, very slim for its time, and feature mostly metallic bodies.^[8][9] Nokia called the E55 the world's thinnest smartphone (it was just 0.1 mm thinner than Nokia E71).^[10] The E55 model has a unique 'compact' QWERTY keyboard featuring two letters in the QWERTY order on a single key.
