I continuously hear some right-wing privacy advocates warning that spam via text message could be a bigger problem than e-mail spam. I, for one, receive on a weekly basis a good number of text message invites for product launches or bar parties. I would classify this as spam simply because the text is emanating from an unknown prepaid number. Aside from that, I hear of many cases where people also receive multiple text invites from unscrupulous content providers literally spamming subscribers without the carrier’s authority. The carriers recently initiated a crackdown and this served to minimize this type of intrusion. Of course, I simply just erase all this spam to free up space in my 400-text message capacity inbox. For most mobile phone users though it becomes a huge inconvenience; the limited storage capacity of their mobile phones makes them unable to receive legitimate text messages. Besides being irritating, it feels like an invasion of one’s privacy, most especially since cellphones are a personal mode of contact.
I, for one, don’t think the same catastrophic barrage of unsolicited marketing messages now plaguing e-mail accounts will ever be seen in our wireless space. The carriers have established firewalls on their networks that restrict the entry of most SMS messages from foreign gateway companies. As such, all SMS spam will only then be coming from within this country. If the spam message is coming from within the Philippines, then the carriers themselves may just as easily block its source. Also to reiterate this fact contrary to broad market belief, every text message has a corresponding cost. The days of free text messages are history, and I believe that this stands as a major factor in controlling mobile spam. I can’t imagine someone bothering to spend a million pesos for load to spam a million people!
The proactive way then to prevent spam is to guard your cell number wisely. Provide your landline number instead whenever your contact info is asked. Furthermore, be wary of some free tone or logo websites. These sites are usually established specifically to harvest cellphone numbers.
