0943 What Network? The 0943 prefix belongs to Smart Communications, one of the Philippines’ largest telecommunications providers. When you encounter a mobile number beginning with 0943, you’re connecting with a Smart Communications subscriber on their nationwide network that covers approximately 96% of the Philippine population.
In the Philippines, mobile phone numbers follow a standard format: a four-digit network prefix followed by a seven-digit subscriber number. These prefixes serve as immediate identifiers of which telecommunications company provides service to a particular number. Understanding these prefixes is essential for consumers who want to identify which network they’re calling or texting, especially since cross-network rates and promotions can differ significantly.
The mobile telecommunications landscape in the Philippines is dominated by several key players: Smart Communications, Globe Telecom, DITO Telecommunity, and Sun Cellular (now fully integrated with Smart). Each company owns specific prefixes that help identify their subscribers within the national numbering plan regulated by the National Telecommunications Commission (NTC).
Among these prefixes, 0943 has become a common inquiry for many Filipinos trying to identify which network they’re connecting with.
What Network is 0943?
The 0943 prefix belongs to Smart Communications, one of the Philippines’ largest telecommunications providers. When you encounter a mobile number beginning with 0943 (or 63943 when dialed from international locations), you’re connecting with a Smart Communications subscriber.
Smart Communications was officially assigned this prefix as part of its number allocation from the NTC. For international callers, the format changes slightly – the leading 0 is replaced by the Philippines country code 63, making it 63943 followed by the seven-digit subscriber number.
This prefix was allocated to Smart Communications during one of their expansion phases as subscriber numbers grew and additional prefixes became necessary to accommodate new customers.
The Smart Communications Ecosystem
Smart Communications stands as one of the Philippine telecommunications industry pillars, serving millions of subscribers across the archipelago. Established in 1991, Smart operates as a wholly-owned subsidiary of PLDT Inc. (Philippine Long Distance Telephone Company), the country’s largest telecommunications conglomerate.
According to the company’s 2024 first-quarter report, Smart Communications maintains approximately 42% market share of the mobile telecommunications sector in the Philippines, with a subscriber base exceeding 30 million users. The company offers a comprehensive range of services including:

Smart’s network infrastructure covers approximately 96% of the Philippine population, with continued expansion into remote areas through its “Smart Communities” initiative that aims to bring connectivity to underserved regions.
“Smart Communications continues to lead digital innovation in the Philippines, focusing on expanding our 5G network coverage while ensuring reliable service across existing technologies.” – Manuel V. Pangilinan, PLDT Chairman (Annual Stockholders’ Meeting, March 2024)

Cross-Network Services and Compatibility
The Philippine telecommunications industry has evolved significantly with the implementation of Mobile Number Portability (MNP) in September 2021. This development allows subscribers to keep their existing numbers when switching between networks like Smart, Globe, or DITO.
Mobile Number Portability Guidelines
Under Republic Act No. 11202 (Mobile Number Portability Act), Filipinos can now switch networks without changing their numbers, including those beginning with 0943. However, there are important considerations:
- Subscribers must have no outstanding balances with their current provider
- The process typically takes 48-72 hours to complete
- A limit of one network switch every 60 days applies
- Porting requests can be submitted online or at physical service centers
According to the Telecommunications Connectivity Inc. (TCI), the joint venture handling MNP implementation, approximately 2.8 million Filipinos had utilized mobile number portability services by January 2025, representing about 2.5% of total mobile subscribers.
Smart-Specific MNP Considerations
For Smart Communications numbers (including those with the 0943 prefix):
- Visit any Smart Store with valid identification to initiate the porting process
- Alternatively, use the Smart Communications app to submit an online request
- Temporary service interruption typically lasts 2-4 hours during the transition
- Smart-to-Smart transfers (e.g., prepaid to postpaid) are processed more quickly, usually within 24 hours
Smart Communications calls this service “Smart Network Change” and has streamlined the process to minimize inconvenience for customers.
Smart Communications vs Other Philippine Networks
Understanding how Smart Communications compares to other major networks provides valuable context for consumers considering which network best suits their needs.
