Spam telephone calls in Colombia increased by 70% in 2025 [1].
This surge highlights a growing vulnerability in mobile security as automated systems outpace traditional blocking methods, leaving consumers exposed to scams.
Data indicates that approximately 16.6 billion spam calls were recorded in Colombia during 2025 [1]. The growth is primarily driven by the use of automated robocall systems and the constant rotation of phone numbers. These tactics allow marketing and scam campaigns to evade traditional blocking filters that typically rely on static lists of known offenders.
Telecom experts and platforms such as Truecaller said that simply rejecting or ignoring a call does not stop the influx of spam. Because these systems are automated, they can generate thousands of calls per minute across a wide variety of numbers, making manual blocking ineffective for the average user.
Experts said that the rise in these calls is linked to more aggressive marketing strategies and a sophisticated increase in fraudulent activities. These campaigns often target broad demographics to find susceptible individuals for various scams.
To combat the trend, technical experts recommend using advanced filtering apps, and supporting regulatory measures to hold automated callers accountable. While individual blocks provide temporary relief, the scale of the problem suggests a need for systemic changes in how telecom providers handle automated traffic.

The massive scale of automated calls in Colombia reflects a global trend where AI and robocall technology lower the cost for scammers to reach millions of people. When the volume reaches billions of calls, the burden of security shifts from the consumer to the telecommunications infrastructure, necessitating stronger network-level authentication to verify callers.
