For people like me who subscribe to different mobile services that takes advantage of same-network rates, knowing the mobile prefix number of each telco is something we need to do.
Above is an image of the list of mobile prefix numbers used in the Philippines which you can save on your phone for quick reference. I have lots of friends and relatives having multiple numbers and I want to take advantage of the cheap rates (Trinet 400 baby!) I get for calling numbers within the same network.
With the image above, I now have a reference so I choose which number to call or text for cheaper rates. Woot!
