Hard to imagine celcom offering extended validity to existing plans. It could happen but I wouldn't hold my breath.

As a general rule, all newer xpax prepaids with basic internet (magicsim, turbo, xpax kelentong) does not have 1 year / 2 years extended validity. ........ Except those who were forced migration from older xpax to xpax kelentong like mua ....

All older xpax still have EXP1 / EXP2 extended validity option.
