JB are having some awesome deals on mobile phone plan packages. The phones on the $150 cap are with $300 vouchers. The other phones are available on Cap plans as well making them really good value. For example I witnessed a customer today buy an E51 on a $49 cap plan - the phone was free and he got a $100 gift card for transferring and then there was also a special where anyone going on the $49 cap plan got a $100 voucher as a bonus.
So all up the customer got an E51 Phone with $200 voucher on $49 cap plan with the phone being free.
I asked if all $49 cap plans had a $100 bonus gift card on top of the gift cards you get with the phones and yes you do.
Then apparently prepaid porting is fine too - so getting a $49 prepaid Optus / Voda prepaid will still work out a good deal.
