0991 What Network: Perfect Guide to Dito Telecommunity Prefix

0991 What Network? The 0991 mobile network belongs to Dito Telecommunity. In the Philippines’ dynamic telecommunications landscape, understanding mobile network prefixes is essential for consumers. The 0991 mobile network has emerged as a significant prefix under Dito Telecommunity, the country’s third major telecom provider. This comprehensive guide explores everything you need to know about 0991 numbers, from network coverage and performance to pricing plans and compatibility issues.

What is the 0991 Mobile Network?

The 0991 prefix belongs exclusively to Dito Telecommunity Corporation, officially confirming that any mobile number beginning with 0991 (or +63991 in international format) is operating under Dito’s network infrastructure. This prefix was introduced in early 2021 as part of Dito’s initial launch in the Philippine market, marking the beginning of a new era in the country’s telecommunications industry.

Mobile prefixes in the Philippines follow a standardized format consisting of four digits after the country code. For Dito’s 0991 numbers, the complete format is:

• Local format: 0991-XXX-XXXX
• International format: +63991-XXX-XXXX

According to the National Telecommunications Commission (NTC), mobile number prefixes serve as identifiers that help route calls and messages to the correct network provider. This system allows for proper routing and billing across the country’s multiple telecom operators.

“The assignment of the 0991 prefix to Dito Telecommunity was part of the regulatory framework to ensure the new telco player could effectively compete in the market dominated by the Globe-PLDT/Smart duopoly,” noted telecommunications analyst Maria Santos of Digital Philippines Research.

About Dito Telecommunity

Dito Telecommunity entered the Philippine market as the third major telecommunications company following a government initiative to break the long-standing duopoly of Globe Telecom and PLDT/Smart Communications. Officially launched for commercial operations on March 8, 2021, Dito is a consortium backed by Udenna Corporation, Chelsea Logistics, and China Telecommunications Corporation.

The company represents a ₱257 billion investment in the country’s telecommunications infrastructure, with a commitment to cover 84% of the population and provide a minimum average internet speed of 27 Mbps in its first five years of operation.

By March 2025, Dito had established a significant market presence:

Metric	Value
Market Share	Approximately 12%
Active Subscribers	15.3 million
Cities/Municipalities Covered	560+
Cell Sites	7,000+
Initial Investment	₱257 billion

This rapid growth has positioned Dito as a legitimate competitor to the established players, particularly appealing to value-conscious consumers and those in previously underserved areas.

Complete List of Dito Telecommunity Prefixes

While this article focuses on the 0991 network, Dito Telecommunity operates several prefixes to accommodate its growing user base. As of March 2025, these include:

• 0991 – Initial launch prefix
• 0992 – Secondary prefix introduced in late 2021

• 0895 – Added in early 2023
• 0896 – Added in late 2023
• 0897 – Added in early 2024

This expansion of number blocks reflects Dito’s growing subscriber base and the NTC’s allocation of additional prefixes to support the company’s market expansion. By comparison, Globe operates prefixes including 0917, 0915, and 0905, while Smart utilizes 0919, 0920, and 0939, among others.

To verify if a number belongs to Dito’s network, you can:

• Check the first four digits (including the 0)
• Use online prefix checking tools like Prefix.ph or Network.ph
• Send an inquiry to Dito’s customer service via 198

Network Coverage and Performance

Dito Telecommunity’s network infrastructure is built on a combination of 4G LTE and 5G technology. The 0991 network, like all Dito prefixes, operates on this modern infrastructure, which has several technical advantages and limitations.

Coverage Map

As of March 2025, Dito’s network coverage has expanded significantly from its initial launch areas. The network now covers:

• 560+ cities and municipalities
• All major urban centers in Luzon, Visayas, and Mindanao
• Most provincial capitals and tourist destinations
• Select rural areas with high population density

However, coverage remains more limited in remote rural locations compared to the established networks of Globe and Smart, which have had decades to build out their infrastructure.

Performance Metrics

Independent tests by Philippines-based mobile analytics firm Opensignal revealed the following performance metrics for Dito’s network in Q1 2025:

• Average Download Speed: 42.3 Mbps
• Average Upload Speed: 8.7 Mbps
• Latency: 31ms
• Video Streaming Quality: Very Good
• Call Quality: Good
• 5G Availability: 38% in covered areas

These figures show significant improvement over Dito’s initial performance metrics and are competitive with, and in some categories surpassing, the established players.

“Dito’s network performance in urban areas has been impressive, particularly their consistent download speeds during peak hours. This suggests effective network management and sufficient capacity in their high-usage areas,” states Jun Reyes, network analyst at Mobile Philippines.

The 0991 network benefits from Dito’s newer infrastructure, which doesn’t carry the legacy technology burden of older providers. However, this also means that coverage expansion happens in phases rather than being universally available.

Pricing and Plans for 0991 Numbers

Dito Telecommunity has positioned itself as a value alternative to the established players, often offering more competitive data packages. For 0991 numbers, all standard Dito plans and promotions apply. As of March 2025, these include:

• DITO 199 – 25GB data (20GB all-access + 5GB daily YouTube) valid for 30 days with unlimited DITO-to-DITO calls and texts
• DITO 499 – Unlimited data with speed cap after 40GB, valid for 30 days with unlimited calls and texts to all networks
• DITO Data Sachets – Small data packages from ₱10 for 1GB (1-day validity) to ₱50 for 5GB (3-day validity)

A key differentiator for Dito’s offerings is the absence of separate pricing for 5G access – all plans include 5G connectivity where available, unlike some competitors who charge premium rates for 5G access.

SIM Registration Requirements for 0991 Numbers

Following the implementation of the SIM Registration Act (Republic Act No. 11934), all SIM cards in the Philippines, including Dito’s 0991 numbers, require registration. The process for registering a Dito 0991 SIM includes:

Required Documents

• Valid government-issued ID (e.g., Philippine Passport, Driver’s License, PhilSys ID)
• Proof of address (if not shown on the primary ID)

Registration Process

• Enter your 0991 mobile number and personal information

According to Dito’s official statistics, over 95% of their active SIMs had been registered by early 2025, with the company implementing various assistance programs to help users complete the process.

“The SIM registration process has been streamlined significantly since its initial implementation, with Dito investing in AI-assisted verification that has reduced processing times from days to hours in most cases,” reports the Department of Information and Communications Technology (DICT).

Failure to register SIM cards results in service deactivation, making compliance essential for continued use of 0991 numbers.

Transferring Your Number to/from 0991

The Mobile Number Portability (MNP) Act enables subscribers to keep their mobile numbers when switching between service providers. This means that:

• Existing Globe or Smart subscribers can transfer to Dito’s network while keeping their original number
• Dito subscribers with 0991 numbers can transfer to other networks while retaining their number

The MNP process typically follows these steps:

• Eligibility Check
  • No outstanding balances with current provider
  • SIM must be actively registered
  • Number must have been in use for at least 60 days
• Porting Request
  • Visit a Dito store (for transfers to Dito)
  • Complete the porting form
  • Present valid ID and proof of number ownership
• Processing Period
  • Standard processing takes 24-48 hours
  • Service interruption is typically minimal (1-2 hours)
• Activation
  • Receive confirmation SMS
  • Begin using the new network with your existing number

According to data from the Telecommunications Connectivity Initiative (TCI), approximately 120,000 numbers are ported between networks monthly, with Dito seeing a net positive influx of transfers in recent quarters.

To check your device’s compatibility, Dito offers an online checking tool on their website or you can verify the supported bands in your phone’s specifications against Dito’s frequency allocations.
