Other mobile numbering developments up to 2010 include:
Number range Carrier/allocation ============ ================== +27 76 reserved - carrier unknown +27 79 reserved - carrier unknown +27 81 Telkom 8ta (pronounced Heita) mobile +27 84 Cell C +27 87 reserved - carrier unknownNextel (new fixed/wireline operator) used Telkom numbering ranges. Mobile number portability is in effect, therefore numbers may not necessarily indicate the current carrier belonging to a wireless number.

Telkom news releases of November 2001 previously indicated the original intention to introduce this overlay code.

Closed 10-digit dialling and number portability were presumably postponed.
Other articles from 2002 on 10-digit dialling proposals:
ITWEB article of 29 September 2003: 10-digit dialling may remain on backburner
ITWEB article of 9 October 2002, Telkom refutes 10-digit dialling rumours - where Telkom refuted rumours that there would be extra charges to callers not using 10-digit local dialling.
Reference: ICASA document (via ITU).
Regulator ICASA intended that 10-digit dialling would be mandatory for local as well as long distance calls. However, the mandatory phase was not implemented.
Permissive operation of either 7-digit or 10-digit local calling began on 6 November 2001.
Mandatory dialling of 10-digit format for all calls would have taken effect 8 May 2002 under the original plan.
However, ICASA announced 4 April 2002 that the parallel operation of 10-digit dialing would continue until six months after "promulgation of the numbering plan regulations". Source: News 24: "Icasa extends dialling phase-in"
Vodacom added +27 72 to its existing +27 82.
MTN added +27 73 to its existing +27 83.
+27 7 and +28 8 ranges are intended for mobile numbers under proposed future national numbering plans.

Also, an area code overlay in Gauteng Central Area (Johannesburg) was proposed, +27 10 added to the +27 11 region.
