If I upgrade my Digi Fibre plan, will I enjoy more rebates on my Digi Postpaid line?

No, your rebate on Digi Postpaid line will be maintained as per your initial Digi Fibre plan sign-up. For example, a subscriber who performs change of plan from Digi Fibre 90 to Digi Fibre 130 will continue to receive RM15 rebate on their Postpaid line.
