guys, after reading few last pages about the discussion that validity365 not available for new hotlink plan, i need confirmation about this.
i have a hotlink number( not newly purchased, so i guess it supposed still in old plan), can i purchase the validity 365 first, only after that migrate to new hotlink plan, to get free whatsapp?
yeah, my only intention is to have free basic internet (whatsapp) with very low commitment, as already have postpaid number for voice call and sms.
my other choice is xpax; get the long validity (1 year/2 year), and reload for mobile data (rm 10 for 150mb), as what i understand its data can be used as long as line active.

guys, please advise... thanks in advance 

i subscribed to 2 years validity and social pack mainly for whatsapp.so far so good.

so 150mb for 2 years?

no lah. our intention is to use the data fully without time limitation, only limited by the validity period, which in this case its two years if subscribe to credit validity. obviously the quota will be finished before two years, but then can resubscribe again and again.
probably what he means is to resubscribe back the mi5 or mi10 once the quota finished.

i'm using the data fully for whatsapp only, phone rooted and firewalled, only allow data for whatsapp on mobiledata. i've also configured whatsapp to automatic download pictures only on mobiledata, videos only download if got wifi. subscribed mi10 back in february, now stil got 26mb left
