There is a story to every single cell phone number in the Philippines. The very first few digits are not random — they carry meaning. They tell you who assigned that number, which operator it came from, and even sometimes what kind of SIM it is. These numbers are called mobile prefixes, and they aren’t what they seem.
So if you are here looking for what network 0939 is under in the Philippines, you are in the right location.
This 2025 guide informs you what carrier 0939 is under, why prefixes are not outdated, how to check if a 0939 number is still Smart or TNT, and why it pays to know your prefix because it can save you money and avoid errors.
What Is a Mobile Prefix?
A mobile prefix is the first four digits after the zero in any Philippine mobile phone number.
Example:

Prefixes are not random. Prefixes are assigned by the National Telecommunications Commission (NTC) to different telecom operators like Smart, Globe, TNT, and DITO.
They facilitate better tracing of which network originally assigned the number and to better control how carriers play across the country.
