If I were on Digi Postpaid 58 when I registered to Digi Internet Freedom 190 or Internet Freedom 290 but decided to upgrade my mobile plan to Digi Postpaid 80 after registration, will I be able to enjoy the ‘More Postpaid Lines, More Savings’ offer?

No, postpaid discounts will be given only at the point of Digi Internet Freedom registration, hence, any upgrades in postpaid mobile plan after registration will not make you eligible for ‘More Postpaid Lines, More Savings’ offer.
