Globe Telecom said it has deactivated 14,013 SIMs, which have been found to be the sources of unwanted and unsolicited text messages.
The mobile operator said the disabled SIMs produced over 400 million spam SMS messages in 2017 which it was able to block using an automated mechanism.
“We understand the problems that could arise from these text messaging scams. This is why we have strengthened our campaign for a spam-free experience for all our customers. We will be constantly upgrading and improving our blocking and filtering mechanism to keep our network from these unwanted messages,” said Anton Bonifacio, Globe chief information security officer.
In 2014, Globe established an anti-spam solution and blocking mechanism, consisting of a new hardware and software solution that can filter up to one billion SMS a day. This mechanism enables Globe to prevent the transmittal of spam/scam messages which have been sent through the Globe network. The following year, the company said it upgraded and expanded the mechanism to effectively prevent spam-scam messages.
With the filtering function and blocking mechanism, Globe has lowered the spam attempts — from 2.9 million daily spam traffic in 2016 to 182,000 in 2017. This represents a 94-percent success rate.
In addition, the number of spam call complaints has been reduced to 1,085, which is 65-percent lower from 3,073 total calls accumulated from 2014 to 2016.
“Text spamming is an industry-wide issue, and we acknowledge that Globe Telecom’s anti-spam campaign will not be as effective without the help of our customers. We encourage our customers to be vigilant and report any text scam they receive,” Bonifacio said.
Customers can file their complaints through www.globe.com.ph/stopspam whenever they receive scam messages. All they need to do is provide details of the spam and scam messages they received on their mobile devices. When Globe has verified that the numbers have been constant sources of spam messages, it will disconnect these numbers from service.
