JOINING BOOST & ACTIVATING YOUR SIM
SETUP & PHONE SUPPORT
RECHARGE & NETWORK SUPPORT
Will save you the reading of my attempts and tries.
Solution!!! (For post-paid anyway...)
Call Boost (1800 100 933)
Hang up when they read you options
Call again, then press 3 (technical support)
Tell them to delete your activation attempt and tell them that you are porting over from a POST-PAID not PREPAID account.
Best of luck,
