The mobile prefix 0981 is officially assigned to Smart Communications, one of the largest and most widely used telecom providers in the Philippines. So, when you ask “0981 what network,” the accurate and up-to-date answer is Smart. Smart Communications is known for its wide network coverage, strong signal quality, and an extensive list of prepaid and postpaid mobile services.
Prefixes like 0981 are designated by the National Telecommunications Commission (NTC), which regulates telecommunications in the Philippines. These prefixes are distributed among telcos like Smart, Globe, DITO, and others to distinguish which network a mobile number belongs to.
Why It Matters to Know 0981 What Network

Many people wonder why it’s even important to know the answer to 0981 what network Here are a few everyday reasons why this simple information can be quite valuable:

To check the actual current carrier of a mobile number post-portability, you might need to:
- Send a test message and observe the response time or promo usage.
- Use an app that can check the real-time carrier.
- Contact the telecom provider for confirmation.
