No, you will not be entitled to enjoy the RM15/month Jaringan PRIHATIN subsidy after you’ve changed to an ineligible plan.

However, you can opt-in again via selfcare after you have changed back to an eligible plan to continue enjoying the subsidy.

For example, if you changed from U28 (ineligible plan) to GX68 (eligible plan), you can continue to enjoy the monthly RM15 subsidy after you have performed the opt-in.
