Nokia 6010/6020/6030: ~75million
Nokia's sold approximately 75 million of its 6010 entry-level handsets worldwide. While U.S. and European markets were important to the phone maker, emerging markets still -- even to this day -- hold the vast bulk of Nokia's revenue. The handset started shipping in the second quarter of 2004 and sold out in huge quantities despite not being made available from the networks. There were two additional iterations, the 6020 and the 6030, which also helped sales.
