wrong lei, you can choose to activate on another day after you collect the sim.
I collected the sim card from the closest MRT station to me as it is free and i activated it > 1 week later online, just 3 days before my billing date for another provider ( my republic) . Activation takes a day, porting takes a day.
Do take note that activating and port might not occur on a sunday or PH.
First month vivifi will pro-rate to end of month and send u a combined bill at end of month 2.
1. Nope, same day cannot unless u heng heng the CSO process your order. Cos they will take some time to process and email you the collection email
2. Yes u can , as my replies above.
3. I say port over on monday. no need cut it so close.
