Recently, Digi has launched the new package for its prepaid customer (Digi Prepaid NEXT confirmed) which is 40GB for RM35 & Unlimited Voice and 20GB for RM30 & Unlimited Voice (both is categorized as 'Unlimited Voice package'. This sounds interesting for me. Refer to the screenshot below.
UPDATE: This plan is NOT available for Digi Prepaid 2017 users. Not sure if Digi Prepaid LiVE can subscribe to this package or not.
UPDATE 2: This plan is only eligible to Digi Prepaid NEXT users and the promotion period is expected to end on this 15th November.
