You can consider that, since biGBonis 28 comes with unlimited calls to all network as opposed to 150+150 minutes on Kaki Social 30.
Do note that once you change to biGBonus 28, your rollover data that you accumulated (if have) on your current Kaki Social 30, will be forfeited.

biGBonus 28 plan comes with 1GB/day from 1-7pm, but no more unlimited Facebook, Instagram and Twitter like Kaki Social 30. So do take note of that.

i took the promotion and regretted it because i use around 100mins call to all network monthly. now digi don't have good package for under rm30 with +mins call.

is it possible to get back kaki social 30?
heard from my friend about 'the rm1/day unlimited internet capped at 4mbps' can be requested thru live agent/call their cs. but the kaki social 30 one alrdy discontinued package. still possible to request from their cs?
