Separately, Millicom launched a new voice messaging service for cellular phones on both the Cellnet and Vodaphone networks: Callbank diverts incoming calls at inconvenient times to a pre-arranged personal number: stored calls can then be replayed by the user by keying in a four-digit security number followed by the Callbank number; connection to Callbank is UKP10, with a monthly subscription of UKP4 – connection to CallBank Standard Plus, which offers the same service but alerts the user that a message has been diverted through a built-in tone pager, with a (possibly irritating) bleep at regular intervals until the messages have been retrieved, costs UKP30, with a monthly fee of UKP18.
