What Network 0077? Discover the Telecom Provider and Benefits in the Philippines

You glance at your phone. An incoming call flashes: 0077-XXX-XXXX. Your first instinct? “What network 0077?” If you’re like most Filipinos, unfamiliar phone prefixes trigger immediate questions—and sometimes concern. Whether you’ve received a mysterious call from this number or you’re simply trying to identify which telecom provider uses this prefix, understanding what 0077 really means is essential.

Here’s the straight answer: 0077 is not a mobile network like Globe, Smart, or PLDT. Instead, it’s a special routing prefix used primarily for international calls and specific telecom services. Understanding what network 0077 belongs to—or more accurately, what purpose it serves—can save you money, protect you from potential scams, and help you make informed decisions about answering or returning calls.

In this comprehensive guide, we’ll break down everything you need to know about the 0077 prefix—from its technical purpose to practical cost implications and verification methods.

Understanding the 0077 Prefix: What It Really Means

The Truth About 0077

Let’s clear up the confusion immediately. The 0077 prefix doesn’t belong to any of the three major mobile networks in the Philippines:

• Not Globe Telecom (which uses prefixes like 0917, 0905, 0906, 0915, 0926, 0927, 0935, 0936, 0937, 0945, 0953, 0954, 0955, 0956, 0965, 0966, 0967, 0975, 0976, 0977, 0978, 0979, 0994, 0995, 0996, 0997)
• Not Smart Communications (which uses 0907, 0908, 0909, 0910, 0911, 0912, 0913, 0914, 0918, 0919, 0920, 0921, 0928, 0929, 0930, 0938, 0939, 0946, 0947, 0948, 0949, 0950, 0951, 0961, 0963, 0970, 0971, 0980, 0981, 0989, 0992, 0998, 0999)
• Not DITO Telecommunity (which uses 0895, 0896, 0897, 0898)

Instead, 0077 functions as an international gateway prefix or special service routing code used by Philippine telecom operators to direct calls through specific channels—particularly for international dialing and value-added services.

How Phone Prefix Systems Work in the Philippines

To understand 0077, you need to know how the Philippine telecommunications numbering system operates:

Prefix Type	Format	Example	Purpose
Mobile Networks	09XX-XXX-XXXX	0917-123-4567	Standard mobile calls
Landlines (Metro Manila)	02-XXXX-XXXX	02-8123-4567	Fixed-line services
Provincial Landlines	0XX-XXX-XXXX	032-234-5678	Regional fixed lines
Special Routing	00XX-XXX-XXXX	0077-123-4567	International/special services

The “00” prefix traditionally signals international dialing or special telecom services. Think of it as a signal to the network: “This call needs special routing.”

Why 0077 Confuses Users

Several factors contribute to the confusion around 0077:

1. It appears unexpectedly on caller ID without explanation
2. Telecom providers don’t widely publicize these special prefixes
3. It resembles mobile number formats at first glance
4. Scammers occasionally spoof international prefixes to seem legitimate

According to the National Telecommunications Commission (NTC), inquiries about unfamiliar prefixes increased by 34% between 2023 and 2024, with international routing codes among the most common sources of confusion.

International Dialing and Special Routing: The 0077 Connection

How International Call Routing Works

When someone calls the Philippines from abroad, or when Philippine-based services route calls internationally, telecom providers use gateway systems to manage these connections. Here’s the simplified process:

Overseas caller dials → International gateway → Philippine telecom network → Your phone displays routing prefix (like 0077)

These routing prefixes serve several purposes:

• Track call origins for billing
• Direct calls through specific carrier agreements
• Enable specialized features like call forwarding
• Facilitate VoIP (Voice over Internet Protocol) integration

Legitimate Uses of 0077

Before assuming every 0077 call is suspicious, consider these common legitimate scenarios:

1. Overseas Family Members Calling Home

If you have relatives working abroad as OFWs (Overseas Filipino Workers), they might use international calling cards or services that route through 0077. These services often provide cheaper rates than standard international dialing.

Example: Your sister in Dubai uses a calling card service that partners with Philippine telecoms. When she calls you, it might appear as 0077 followed by additional digits.

2. Business and Corporate VoIP Systems

Many multinational companies and BPO (Business Process Outsourcing) operations in the Philippines use VoIP systems that integrate with traditional phone networks. These systems sometimes display 0077 when routing calls.

3. International Conference Calls

Professional conferencing platforms that connect participants from multiple countries may use special routing prefixes when displaying Philippine-based numbers.

4. Call-Back Services from Overseas Contacts

Some international customer service centers use automated call-back systems. When they return your call, the routing may show 0077 instead of the actual overseas number.

“We receive numerous inquiries about international prefixes like 0077,” notes a customer service representative from a major Philippine telecom provider. “Most cases involve legitimate international calls that users simply don’t recognize because the prefix differs from standard mobile formats.”

Major Telecom Providers and Their Use of 0077

While 0077 isn’t owned by a specific network, all major Philippine telecom operators utilize international routing systems that may involve this prefix.

PLDT’s International Services

PLDT (Philippine Long Distance Telephone Company), the country’s oldest telecom provider, offers extensive international calling services:

• PLDT Home subscribers can access International Direct Dialing (IDD) services
• PLDT Global provides discounted international rates to key destinations
• Enterprise solutions include virtual numbers and international call forwarding

When PLDT routes international calls to or from the Philippines, various prefixes including 0077 may appear depending on the specific gateway used.

Typical international call rates from PLDT:

• Calls to USA/Canada: ₱12-15 per minute
• Calls to Middle East: ₱18-25 per minute
• Calls to Asian countries: ₱8-20 per minute

Globe Telecom’s International Framework

Globe Telecom operates one of the most extensive international networks in the Philippines:

• Globe international roaming services in over 200 countries
• Call forwarding capabilities that work across borders
• TM (Touch Mobile) prepaid international calling options

Globe’s partnerships with international carriers mean that calls routed through their network may display various special prefixes, including 0077, depending on the origin and routing path.

Smart Communications International Services

Smart Communications and its subsidiary TNT (Talk ‘N Text) provide:

• International call packages with competitive per-minute rates
• Smart Buddy IDD services for prepaid users
• Corporate international calling solutions

Smart’s international gateway agreements with carriers worldwide can result in 0077 prefixes appearing on calls routed through their infrastructure.

Third-Party VoIP and Call Services

The rise of internet-based communication has added complexity to phone prefix identification. Services like:

• Skype (using SkypeOut features)
• WhatsApp calling with number integration
• Viber Out for calling non-Viber numbers
• Specialized international calling apps

These platforms sometimes partner with Philippine telecom operators to complete calls to regular phone numbers. The technical handoff between internet and traditional phone networks can generate unfamiliar prefixes like 0077.

According to industry data, VoIP usage in the Philippines grew by 42% between 2022 and 2024, driven largely by cost-conscious consumers seeking alternatives to traditional international calling.

Cost Implications: What You Need to Know

Understanding the financial side of 0077 calls is crucial for avoiding unexpected charges.

Potential Charges When Dealing with 0077

Receiving Calls from 0077: Generally, receiving calls is free regardless of the prefix. Philippine mobile networks operate on a “calling party pays” system, meaning the person making the call bears the cost, not the recipient.

However, there are exceptions:

• If you’re roaming internationally when you receive the call
• If you’ve activated special premium services that charge for incoming calls (rare)
• If the call is part of a collect call arrangement (which requires your consent)

Returning Calls to 0077: This is where unexpected charges commonly occur. If you try calling back a 0077 number without understanding its nature, you might trigger:

• International calling rates (₱15-75 per minute depending on destination)
• Special service fees if the number connects to premium services
• Roaming charges if you’re traveling

Cost Comparison Table:

Scenario	Typical Cost	Notes
Receiving 0077 call (local)	Free	Standard for all networks
Receiving 0077 call (roaming)	₱15-50/min	Varies by country
Calling back 0077 (if international)	₱15-75/min	Depends on destination country
International IDD rates (USA)	₱12-15/min	Using carrier direct
International IDD rates (Middle East)	₱18-25/min	Using carrier direct

Money-Saving Tips

Before calling back any 0077 number:

1. Check with your telecom provider first – Call customer service (PLDT: 171, Globe: 211, Smart: 888) and ask them to identify the number
2. Use your provider’s app – GlobeOne, Smart app, or MyPLDT can show detailed call information
3. Consider VoIP alternatives – If you need to reach someone internationally, use Messenger, Viber, or WhatsApp calls instead
4. Review your plan’s inclusions – Some postpaid plans include international minutes
5. Set spending limits – Most providers allow you to cap international calling expenses

How to Verify and Trace 0077 Calls

Verification is your best defense against both unexpected charges and potential scams.

Official Verification Methods

1. Contact Your Telecom Provider Directly

This is the most reliable method. Call your provider’s customer service:

• PLDT: 171 (for PLDT subscribers)
• Globe: 211 (for Globe/TM subscribers)
• Smart: 888 (for Smart/TNT subscribers)

Provide the complete number including the 0077 prefix. Representatives can tell you:

• Whether it’s an international call
• The approximate origin country
• Whether returning the call will incur charges
• If the number is associated with known scam patterns

2. Check Your Billing Statement

Your monthly bill or prepaid transaction history contains detailed information about:

• Incoming call sources
• Duration and time of calls
• Any charges incurred
• Call classification (local, international, special services)

3. Use Official Telecom Apps

Modern telecom apps provide real-time call information:

• GlobeOne (Globe/TM): Shows call logs with detailed metadata
• Smart Communications App: Provides call classification
• MyPLDT: Offers call tracking for both mobile and fixed-line services

Online Tools and Resources

Several online platforms claim to identify phone numbers, but use them with extreme caution:

Safer options:

• Official NTC (National Telecommunications Commission) website for advisories
• Philippine telecom provider directories
• Legitimate consumer forums like TipidCP or PinoyExchange telecommunications sections

Avoid:

• Third-party apps requesting excessive permissions (contacts, messages, location)
• Websites requiring payment for basic number lookup
• Services promising “instant identification” of unknown numbers

Red Flags: Identifying Scam Calls

The NTC and Philippine National Police Anti-Cybercrime Group have identified common scam tactics involving international prefixes:

Warning signs of fraudulent calls:

• Pressure tactics: “Your account will be closed in 24 hours unless you act now”
• Requests for sensitive information: OTP codes, bank details, credit card numbers
• Prize or lottery claims: “You’ve won ₱500,000—just pay the processing fee”
• Government impersonation: Fake NBI, BIR, or immigration officials demanding immediate payment
• Threatening language: Claims of arrest warrants, deportation, or legal action

According to PNP Anti-Cybercrime Group data from early 2024, phone scams involving international prefixes increased by 28% compared to the previous year, with an average victim loss of ₱45,000.

Remember: Legitimate organizations will never ask for:

• Your full bank account number over the phone
• Credit card CVV codes
• One-time passwords (OTPs)
• Money transfers to “verify” your identity

What to Do If You Suspect Fraud

If a 0077 call seems suspicious:

1. End the call immediately – Don’t engage or provide any information
2. Document everything – Screenshot the number, note the time and claims made
3. Report to authorities:
   • NTC hotline: 1-3-1
   • PNP Anti-Cybercrime Group: (02) 8723-0401 local 7491
   • Your bank’s fraud hotline (if financial information was discussed)
4. Block the number on your device
5. Warn others – Share your experience on legitimate consumer protection platforms

Frequently Asked Questions About What network 0077

Is 0077 a legitimate phone prefix in the Philippines?

Yes, 0077 is a legitimate special routing prefix used by Philippine telecom operators for international calls and specific services. However, its legitimacy depends on context. If you’re expecting a call from abroad or have international business contacts, a 0077 call is likely genuine. If you receive unexpected 0077 calls with suspicious requests, treat them with caution and verify through official channels.

Can I call a 0077 number back without incurring charges?

This depends entirely on where the call is actually routed. If the 0077 number connects to an international destination, you’ll incur international calling rates (₱15-75 per minute). Always verify with your telecom provider before calling back. Use their customer service hotline or mobile app to check if charges will apply.

Why am I receiving calls from 0077?

Common reasons include:

• Family or friends calling from overseas
• International business contacts

• VoIP services routing through Philippine networks
• Unfortunately, also potential scam attempts

Context matters. If you have legitimate international connections, 0077 calls may be routine. If calls are unexpected and suspicious, verify before engaging.

Are there special promos for international calls using 0077?

The 0077 prefix itself doesn’t have specific promos, but all major Philippine telecoms offer international calling packages:

PLDT: PLDT Global plans with discounted IDD rates Globe: International calling add-ons starting at ₱50 for specific minutes Smart: IDD packages for frequent international callers

Contact your provider to inquire about current international calling promotions that might reduce your costs.

How do I block unwanted 0077 calls?

What’s the difference between 0077 and other 00XX prefixes?

The “00” prefix family (0077, 0078, 0079, etc.) generally indicates international or special service routing. The specific digits after “00” may route calls through different international gateways or service platforms. Functionally, for most users, these prefixes serve similar purposes—marking calls that involve international connections or specialized telecom services.

Can OFWs use 0077 to call home cheaply?

The 0077 prefix is a routing indicator, not a calling method. OFWs looking for affordable ways to call the Philippines should consider:

• VoIP services: Viber, WhatsApp, Messenger (free with internet)
• International calling cards: Often cheaper than direct dialing
• Telecom-specific apps: Globe’s GCall, Smart’s Talk2PH
• Special OFW rates: Many carriers offer discounted rates for calls originating from countries with large Filipino populations

Conclusion: Knowledge Protects and Empowers

The 0077 prefix isn’t a mysterious mobile network—it’s a technical routing indicator for international and special service calls in the Philippine telecommunications system. While all major providers (PLDT, Globe, Smart) use such prefixes in their international call infrastructure, understanding what 0077 represents gives you three critical advantages:

1. Security: You can distinguish potentially legitimate international calls from suspicious activity
2. Cost control: You’ll avoid expensive accidental call-backs and choose appropriate communication methods
3. Confidence: You’ll handle unfamiliar phone numbers with knowledge rather than uncertainty

Before responding to any 0077 call: Verify the source, check potential costs, and trust your instincts. When in doubt, contact your telecom provider’s customer service for clarification.

The next time your phone displays a 0077 number, you’ll know exactly what it means—and how to respond appropriately.
