1) Upfront Payment: Let say it RM600, 600/10=60. Then it will rebate from your monthly payment - RM108-60=RM48 (not include any tax if have). Every month till 10 months.

2) Yes, u will tie with DIGI for 24 months.

It depends on terms and conditions for that telco. Each telco different term and conditions. For example, I use celcom postpaid package with iphone and 24 months contract. I need to stick with it for 24 months and cannot downgrade to cheapest package or have other better promotion from celcom.

If upgrade from i98 to i128 can if im not mistaken. Only upgrade is possible within the time of that contract. If downgrade have some fine will be charge. Change postpaid number to prepaid im not sure.

This is what I know, if have mistake, other forumer please correct me.
