The first payment that you're going to make is RM 1758.

Let's take the Note 2 - U58 plan that you wanted to take as an example.
In the U Mobile's comparison, it compares between:
retail price of the phone + U58 vs discounted price for the phone + U58 for a period of one year.

Retail Price + U58 = 1999 + (12 * 58) = RM 2695
Discounted Price + U58 = 1468 + 290(290 / 58 = 5 months of U58 upfront payment) + 406(remaining months that are to be paid = 7 * 58) = RM 2164

Savings: RM 2695 - 2164 = RM 531(which tallies to the amount that is on the site as well)

but seriously, these plans are only good if you're to buy a phone when it has just been released to the market......... 

yeah, and from a quick search in lelong, ori set note 2 is 1499.

so total =1499+(12*58)=2195

slightly more expensive than the package, but you are not tied down to the contract, you can switch and terminate within the 12 months.(IINM la, have to recheck since I am using prepaid, so i am not sure whether there is a contract  if you take a postpaid plan without any subsidized phone)
