if you will avail a booster (SUPERSURF 999) on top of your MRF your peso value will consumables, having combos is just an option.
combo is required but booster is optional...
Combos and Boosters are not required. If you won't choose any booster, your peso value will be your consumable amount.
Combos are allocations that can be deducted to your peso value. You are not required to have one but it is advisable to avail combos.
Boosters are promos that you can register and will be charged on top of your bill.
Thanks everyone. Now I know which Plan to get.
