KEY POINTS:
Telstra is more than two months ahead of schedule on the rollout of its 3G mobile network in Australia.
The company is spending A$1.1 billion replacing its CDMA network - the same technology as Telecom's mobile network.
Telecom mobile customers use Telstra's CDMA network when roaming in Australia.
A Telecom spokesperson said they were not aware of any change in the timetable for switching off CDMA in Australia.
Telstra's CDMA network is due to be shut down in January next year.
