Do you wonder as to whose network that unknown number belongs too? As you all know, most of the promos of the networks cover only calls between the same network. Just like me, I bet, you don't want to be charged with inter-network charges as much as possible.
To save you from your predicament, I decided to make a list of Mobile Network Prefixes in the Philippines.
Here are the list of the mobile number prefixes so you would not wonder anymore if you'll reply to them or not.
Smart numbers and TNT numbers

Globe Numbers and Touch Mobile Numbers
Here are the prefixes of the numbers of Globe Telecommunications and its subsidiary, Touch Mobile.
If you're wondering what the heck is Next Mobile. Then wonder no more, Next Mobile is the mobile network owned by the Iglesia Ni Cristo.
