What do I make of this text message? (Legit or scam?)

[Alpha_One]

I received the following text message this afternoon from an unknown number (hindi ko na ipapaskil for privacy reasons):

May importante akong sasabihin sayo. Hindi na ako makakareply call back ka nalang o share 5 pesos na load. Eto bagong number ko,

I'm inclined to think that this is a scam because:
- Hindi nagpakilala ("bagong number" raw, may presumption na kilala ko ang nagpadala)
- Kung importante, I'm sure it was worth his/her while to send me what he/she wanted to say in the first text message (i.e. yung nasa taas). If it was really that important, I'm sure the information was much more valuable than 5 pesos or a few minutes worth of load on a phone call.

On the one hand...:
- 5 pesos lang ang hinihinging load. Parang masyado maliit para sa isang scam

...but on the other hand:
- Pareho kami ng network. It's highly possible that this person's unlimited text session is running out and he/she's just fishing for some extra load for another unli-text session.

Hindi na ako sumagot. I don't reply to texts from unknown numbers whose senders don't identify themselves. Ang tanong ko lang is, what do you think of it? Nakatanggap na ba kayo ng ganitong message?
