The Nokia 2100 is a mobile phone announced in Nov 4, 2002, and released in Q1 2003. It is a derivative of the more popular Nokia 1100 and serves as a spiritual successor to the Nokia 8210, sharing a similar button layout, firmware and small dimensions. It is rebranded as Nokia 3610 for some markets.

It also included some of the popular Nokia games available, which were Space Impact, Snake II and Link5. Space Impact most notably, included better graphics than the Nokia 3310 and others, but being rather slow and having bad framerate.

Despite having black and white display, and it having low resolution, Nokia 2100 included graphic redactor for images, which people could then save and send via MMS.

On the back it included a slot, in which people could insert a small photograph, or a very slim object, and see it through the plastic cover.

It was succeeded by the Nokia 3510.
