Have you received a call or text from a number starting with 0977 and you’re not sure if it’s from Globe or Smart? In the Philippines, mobile prefixes play an essential role in identifying which network a mobile number originally came from. This guide explains everything about the 0977 prefix, the network it belongs to, and how mobile number portability affects it today.
Understanding Mobile Prefixes in the Philippines
What Are Mobile Prefixes?
A mobile prefix in the Philippines is the first four digits of an 11-digit phone number. For example, in 0977-123-4567, 0977 is the prefix that initially identifies the network provider.
Why Mobile Prefixes Matter
Recognizing prefixes helps you:
- Choose the right promo for your network
- Avoid higher cross-network charges
- Ensure better communication efficiency for personal or business use
What Network Is 0977?
Official Network Assignment
The 0977 mobile prefix is officially assigned to Globe Telecom, one of the largest telecommunications providers in the Philippines.
| Prefix | Network Provider | Type | Parent Company |
| 0977 | Globe Telecom | Prepaid/Postpaid | Globe Group |
So if you’re reaching out to a 0977 number, you’re most likely connecting to a Globe subscriber—unless the number has been ported.
About Globe Telecom
Globe Overview
Globe Telecom offers a wide range of services, including prepaid and postpaid mobile plans, broadband internet, and enterprise solutions. It’s part of the Ayala Corporation, a long-standing conglomerate in the country.
Subsidiary Brands and Integration
Globe also operates TM (Touch Mobile), which shares infrastructure and often allows intra-network promos to apply between TM and Globe users.
Mobile Number Portability (MNP) in the Philippines
What Is MNP?
Mobile Number Portability (MNP) allows users to switch telecom providers without changing their mobile number—including the prefix. So while 0977 is a Globe prefix, it could now belong to Smart, DITO, or other networks if ported.
How This Affects the 0977 Prefix
With MNP:
- A 0977 number might appear to be from Globe, but it could be registered to another provider.
- Verifying the current network is important if you’re using network-specific promos.
How to Verify a 0977 Number’s Current Network
Options for Checking Network Status
To know if a 0977 number is still with Globe, you can:
- Use online or app-based network checker tools
- Contact your network’s customer service
- Test with a network-specific promo and check if it gets charged extra
Business Perspective
For businesses that use bulk messaging or customer support lines:
- Verifying actual network helps reduce communication costs
- Ensures promo compatibility
- Prevents failed message deliveries due to cross-network issues

Benefits of Knowing If 0977 Is a Globe Number
Promo Compatibility
If you’re subscribed to Globe-exclusive call or text promos, confirming the 0977 number’s network status helps you avoid unnecessary charges.
Cost-Saving
Calling within the same network typically reduces communication expenses. Knowing that 0977 is a Globe prefix allows you to communicate affordably using intra-network offers.
App Registrations and Service Compatibility
Apps or services that require a Globe number for activation or registration often verify the prefix. Knowing that 0977 is officially Globe helps ensure smooth setup.
