i think 1 year validity no grace period.

i see... not sure for this tablet plan though.

last time my friend bought validity 365 (not tablet plan) and he thought have the grace period after the 365 days. so he didn't top up until 366th days all his rm400 credit inside gone together with his prepaid number. he went to maxis centrebut could not get his money back. they told him his number still available but he need to queue for the number to reborn, and as a postpaid line not prepaid already.
