if you are maxis loyal customer (few years with maxis i assume), your device advance will be waive
they scare you run away with the device subsidize, for example new customer sign up MOP158, pay RM4105 + 6%, then didnt continue to pay monthly 158.... if you are loyal customer, maxis will waive the device advance, because ipx 256gb is RRP5899, you only pay RM4105 + 6%, then you can walk away with it

who knows some people never continue to pay maxis
if you need to pay device advance, they will return you monthly, let say u pay RM834, they will credit back to you in few months on your bills...
let say credit back within 6 months, RM834 / 6, each month your bill is (RM158 + 6%) - RM139.... something like that

i assume 6 months, not so sure how long, maybe 12 months
p/s: BUT you cant really do that just walk away without pay monthly, telco can lock the phone if you owe them money....

Owh got it! Thanks bro. They will waive device advance automatically whn placing order i assume?
