Although designed with simplicity in mind, a carefully selected set of features adds to the utility of the Nokia 2135 without adding any unneeded complexity. An integrated speakerphone allows the whole family to join in the conversation at once, while user-assignable ringtones can announce who is calling without ever picking up the phone. For keeping everyday life organized, a built in calendar means that birthdays and anniversaries are never forgotten, and a built-in voice recorder can store up to 60 seconds of audio notes at a time, providing an effortless way to be reminded of everything from picking up milk at the store to where the car is parked at the mall.

The Nokia 2135 is expected to be available in North America during the fall of 2007.
