Switched to Vodafone for a moment cause Optus still arnt pricing themselves like they torched their brand, and boost actively incentivise you to port out then port back in. Itβs not horrific, but man Iβm outta the house 50 minutes and notching the network gaps pretty bad!
Boost almost ALWAYS have a good deal going. Extra data for 3 months, or cashback on a prepaid sim. But for an existing customer? you get none of that. So you're better off porting in and porting out every time the deal ends. A bit like changing your NBN provider every 6 months.
