Back in the 90’s, SMS used to be free and unlimited with every SIM. Then, the telcos cut them off and offered free SMS quotas. Then they introduced promos and offered back unlimited text messaging.
This time around though, its becoming more of a problem rather than a convenience. And during times like elections, the issue has become more prominent — SMS spam.
Before the unlimited SMS were re-introduced, text spamming can be costly — that’s like Php1.00 for every SMS sent. Today, the just go and but a prepaid SIM from each of the carriers, load it up with as low as Php15 and sign up for unlimited text for 24 hours. That’s it — they can spam all they want without fear of being caught (it’s a prepaid number anyway).
One other solution would be to require registration for every prepaid SIM card bought but that would be close to impossible here in the Philippines (we’re very privacy-sensitive around here).
Or maybe, just make spamming a little more expensive like putting a cap in SMS transmission (e.g. 1 SMS per 10 seconds) or maybe just hike the free daily SMS into the hundreds (500 SMS per day perhaps?).
Is there any better way to stop or even just minimize SMS spam? Or is the unlimited SMS promo just too lucrative a sales funnel to even bother?


I agree with Manong. Raise the price of prepaid SIM cards. It’s almost shocking how you can buy a SIM for as low as 10 pesos today when it was 1,000 pesos when I bought my first ever Globe SIM in year 2000.
