The telco has already offered free local, national and mobile calling from its 300 payphones around the quake-struck city, plus free call-forwarding for those hit by property damage.

Telecom, Vodafone and 2degrees have all reported that their mobile networks are now fully operational, albeit with some systems still running on backup power.
