0981 What Network Is It Assigned To?
Let’s get straight to the point: 0981 is a prefix assigned to Smart Communications. Smart is one of the leading mobile network operators in the Philippines and serves millions of prepaid and postpaid users across the country.
So, when you ask “0981 what network,” the answer is Smart. This means that if you’re calling or texting a number beginning with 0981, you’re contacting someone on the Smart network—unless the number has been ported to another network through Mobile Number Portability, which we’ll also cover later.
Why It’s Important to Know 0981 What Network

You might wonder, why does knowing the answer to 0981 what network even matter? Here are some practical reasons why this information is useful:
- Promo Compatibility: Many telecom promos—especially unlimited text or call bundles—are limited to same-network usage. If you’re a Smart user and your contact’s number starts with 0981, you’ll be covered.
- Cost Savings: In the Philippines, calls and texts to a different network (off-network) typically cost more than in-network communication. Identifying 0981 as part of Smart helps avoid those extra charges.
- Business Use: If you manage bulk messaging or client communications, knowing the networks of your recipients helps optimize costs and delivery success rates.
- Spam and Scam Awareness: Scam messages often come from random or less familiar prefixes. Knowing which ones are legitimate, like 0981 under Smart, helps build trust or spot suspicious numbers.
So, understanding 0981 what network is really about being more informed and financially efficient in your day-to-day mobile use.
How to Check If 0981 Is Still a Smart Number
As mentioned earlier, 0981 belongs to Smart, but there’s one caveat—Mobile Number Portability (MNP). Since MNP was implemented in the Philippines, mobile users can now switch networks while keeping their original number. This means a number that starts with 0981 may have been transferred to Globe or DITO, even though the prefix originally came from Smart.
To be sure of a number’s current network, here are some ways to check:
- Prefix Checker Apps: Download mobile apps like PreFIX PH, which identifies the current carrier based on real-time network data.
- Network Inquiry via Customer Support: Contact Smart or use online network identification tools provided by telecoms to verify if a number is still under their system.
- Send a Message: If your promo includes limited network-based messaging, a quick way to test is by sending a message. If the promo isn’t valid, the system might notify you that the number is out-of-network.
Despite MNP, most 0981 numbers remain with Smart. So, when asking 0981 what network, Smart is still the default and most likely answer.
Understanding Mobile Prefixes Like 0981 in the Philippines
Mobile number prefixes are the first four digits of an 11-digit mobile number (excluding the country code). These prefixes are issued by the National Telecommunications Commission (NTC) to different telecom providers to help identify which company owns a particular number range.
For example:
- Globe: 0917, 0956, 0966, 0977
- Smart: 0918, 0947, 0998, 0981
- DITO: 0991, 0992, 0895
This makes the prefix a quick identifier for mobile users. So when someone asks “0981 what network,” they’re essentially trying to determine the telco behind that number. This system makes it easier for users to manage promos, identify spam, and choose the best communication options.

Things to Consider When Calling or Texting 0981 Numbers
Even though 0981 numbers are under Smart, here are a few things to consider before making that call or sending that message:
- Is it Ported? As discussed, MNP could mean the 0981 number is now using a different network. Use apps or inquiry tools to verify.
- Promo Validity: If you’re using an unlimited or discounted promo, make sure it covers 0981 (or Smart numbers) to avoid unexpected charges.
- Roaming and International Use: If you’re abroad or calling an 0981 number from outside the Philippines, the prefix can help customer support or operators guide you through international dialing.
