Can you sign up to the nbn with Optus online and get the 3 months free deal? Or does it have to be done over the phone? If I’m currently with Optus but sign a new nbn contract will I get a new premium modem ?
You would be best off discussing your individual circumstances with Sales.
Online offers tend to be for "new customers" not "converting" customers, however, I don't see the harm in them trying. That said, they don't generally offer the "premium modem" for free.
