We're glad that you've considered upgrading your plan.
The usual activation of the new plan may take within 4 to 24 hours once it was lodged. You may process the change of plan anytime you want, since any unused portion of your current billing will be used towards the new plan.
Some additional info on upgrading:
1) The change of plan fee (same location) is $0 ? Yes, there's no charge for changing your NBN plan.
2) Will I retain my UNI-V phone connection and NOT be required to switch to VOIP ? NBN uses VoIP technology to provide you the bundled phone service. You will use the same setup as it is already configured as VoIP. (Same UNI-V phone connection)
3) My current equipment is working perfectly (NO VOIP) and therefore would I require an equipment upgrade? No, you'll use the same equipment available.
Regards
Bryan
