0923 what network? If you’ve ever received a call from a number starting with 0923 and wondered which provider it belongs to, the answer is Smart Communications. The 0923 mobile network is part of Smart Communications, one of the Philippines’ leading telecommunications providers.
In the country’s diverse telecom landscape, mobile prefixes like 0923 serve as digital identifiers that instantly reveal the service provider behind any phone number. Whether you’re trying to identify an unknown caller, choose a new mobile number, or simply understand the complex web of Philippine telecom infrastructure, knowing the networks behind these prefixes is essential knowledge for any mobile user.
0923 Network Identity: Smart Communications Profile

The 0923 prefix (internationally dialed as 63923) is officially assigned to Smart Communications, the wireless services division of PLDT Inc., the Philippines’ largest telecommunications company. This prefix has been part of Smart’s number allocation since the early 2010s, representing one of their more established number blocks in their extensive prefix portfolio.
Smart Communications has maintained a strong market presence since its founding in 1991, and as of March 2025, holds approximately 42% of the Philippine mobile telecommunications market according to data from the National Telecommunications Commission (NTC). The company serves over 70 million subscribers across its various brands, including Smart, TNT (Talk ‘N Text), and previously, Sun Cellular (now fully integrated under the Smart brand).
“Smart Communications’ network infrastructure has seen over PHP 210 billion in investments between 2020 and 2025, significantly improving service quality across all prefix blocks, including the 0923 network,” noted telecommunications analyst Maria Santos in a recent industry report.
Smart’s parent company, PLDT, has leveraged its fixed-line network infrastructure to support Smart’s mobile services, creating one of the most extensive telecommunications networks in Southeast Asia. This integration has particular benefits for 0923 prefix users, who can access cross-platform services and bundled promotions across the PLDT ecosystem.
Technical Aspects of the 0923 Prefix
Understanding the technical structure behind the 0923 mobile network helps clarify how the Philippine numbering system operates. The prefix 0923 follows the standard Philippine mobile number format:
0 + Network Prefix (3 digits) + Subscriber Number (7 digits)
When dialing from international locations, the format becomes:
+63 + Network Prefix without the leading 0 (923) + Subscriber Number (7 digits)
This explains why 0923 and 63923 both identify the same Smart Communications network, with the difference being domestic versus international dialing formats.
Regarding technical infrastructure, Smart’s 0923 numbers operate on the following spectrum allocations:
| Band | Frequency | Technology | Primary Usage Areas |
|---|---|---|---|
| Band 1 | 2100 MHz | 3G/4G/5G | Urban centers, high-density areas |
| Band 3 | 1800 MHz | 4G LTE | Nationwide coverage |
| Band 5 | 850 MHz | 3G/4G | Extended coverage, rural areas |
| Band 28 | 700 MHz | 4G LTE | Building penetration, rural coverage |
| n78 | 3500 MHz | 5G NR | Metropolitan areas |
The 0923 prefix benefits from Smart’s recent infrastructure upgrades, with approximately 97% of these numbers now having 4G LTE access and about 78% falling within Smart’s 5G coverage areas in major cities like Metro Manila, Cebu, and Davao as of early 2025.
Smart Communications’ Complete Prefix Portfolio
While 0923 is one prominent Smart Communications prefix, the company manages numerous other prefix blocks. Below is a comprehensive breakdown of Smart’s prefix allocations as of March 2025:
Smart Postpaid and Prepaid Prefixes:
