CallZone

CallZone was a service offered by SingTel (then known as Telecommunications Equipment) in the 1990s. The service allowed users to make, but not receive, calls using a special handset made by Motorola, in certain zones.

Description

The CallZone service was introduced sometime in 1990 or 1992.

Users who subscribed to the service were given a Motorola-made flip-phone to make calls. These calls could only be made in certain areas with a CALLZONE sign. It is widely reported that areas with CALLZONE towers also had payphones located in the vicinity, thus negating the need for one.

Two models of CallZone phones were made. The premium model had a built-in pager. Both were flip-phones, and had rubber trimming on the sides that came in multiple colours.

The network was shut down in 1997. It is thought that this was due to M1 entering the telco market, thus offering competition.

The CallZone name was resurrected for a service, also offered by SingTel. The service allows SingTel subscribers to make free calls, using a special device connected to a SingNet Broadband modem.
