1. Vietnam GEO Overview: Why Affiliates Should Care
Vietnam is one of the strongest mobile-first GEOs in Southeast Asia and a long-term growth market for affiliate marketing. With a population of over 100 million people, high smartphone penetration, and an audience that is highly engaged with mobile content, Vietnam consistently delivers scalable traffic for affiliates who know how to work with local specifics.
This is a GEO where mobile traffic dominates, multiple SIM usage is common, and users are already comfortable with mobile payments, digital wallets, and carrier-based services. For affiliates working with mobile subscriptions, fintech, apps, gaming, or e-commerce, Vietnam is not a “test GEO” — it is a scalable core market.
Key macro facts:
- Population: ~100–101 million
- Mobile connections exceed population size (multi-SIM behavior)
- Majority of users access the internet via smartphones
- Social and video platforms are core traffic sources
Vietnam is not Tier-1 by payouts, but it compensates with volume, stable conversion rates, and long-term LTV when funnels are built correctly.
2. Mobile Market Structure in Vietnam
Vietnam’s telecom market is highly concentrated. Three operators control the vast majority of mobile subscribers, which simplifies scaling but also requires understanding operator-specific behavior, policies, and billing logic.
Top Mobile Operators by Market Power
1. Viettel — Absolute Market Leader
Viettel is the number one operator in Vietnam, controlling the largest share of mobile subscribers in the country.
- Estimated market share: ~45–50 percent
- Strongest nationwide coverage (urban + rural)
- Government-linked structure, very stable infrastructure
- Deep ecosystem: mobile internet, mobile money, fintech, enterprise services
Why Viettel matters for affiliates
- Best operator for carrier billing and mobile subscription flows
- Strong SMS and VAS infrastructure
- High trust level among users
- Excellent reach outside Tier-1 cities, where traffic is cheaper
If you run mVAS, carrier billing, app installs, fintech, or paid content, Viettel traffic usually delivers the best volume and the most predictable results.
2. VinaPhone (VNPT Group)
VinaPhone is part of the VNPT state telecom group and is the second major player in Vietnam.
- Strong presence in cities and suburban areas
- High-quality mobile data network
- Integrated with fixed internet and corporate services
Affiliate perspective
- Good operator for data-heavy offers (streaming, apps, subscriptions)
- Stable traffic quality
- Slightly more conservative with billing rules compared to Viettel
3. MobiFone
MobiFone is the third major operator and still controls a significant share of the market.
- Solid urban penetration
- Competitive data packages
- Actively targets younger demographics
Affiliate perspective
- Performs well with youth-oriented offers
- Often good for social traffic and entertainment subscriptions
- Needs careful funnel optimization to maintain approval rates
4. Vietnamobile
Smaller operator focused on price-sensitive users.
- Budget tariffs
- Promotional packages
- Smaller coverage
Affiliate perspective
- Works for low-ticket offers
- Can be tested for SMS or entry-level subscriptions
- Limited scaling potential
5. Gmobile
Niche operator with limited influence.
- Very small market share
- Used mostly for specific use cases
Affiliate perspective
- Not a core scaling operator
- Only relevant in very specific setups
3. Mobile User Behavior & Cultural Factors
Understanding local behavior is critical in Vietnam. This GEO is not about aggressive funnels — it is about mobile-native UX and trust.
Mobile-First Mentality
Vietnamese users live on their phones. Most:
- Browse social media
- Shop online
- Watch videos
- Pay for services
all directly from mobile devices.
If your landing page is not perfectly optimized for mobile, you will lose money.
Payments & Trust
Vietnam is rapidly adopting:
- Mobile wallets (MoMo, ZaloPay, ViettelPay)
- In-app payments
- Carrier billing for digital services
At the same time, users are sensitive to:
- Hidden charges
- Unclear subscription terms
- Complicated unsubscribe flows
For affiliates running subscriptions, transparency is mandatory. Clear pricing and visible cancellation options are not optional — they directly affect approval rates and long-term payouts.
Content & Messaging
- Local language performs significantly better than English
- Short video formats dominate
- Emotional, simple, benefit-driven messaging converts best
- Overly aggressive “get rich quick” or misleading creatives get burned fast
4. What Works Best in Vietnam Affiliate Marketing
High-Performing Verticals
Mobile Subscriptions and mVAS
Vietnam is one of the strongest GEOs in SEA for:
- Entertainment subscriptions
- Utility content
- Short-term paid services
Carrier billing works especially well with Viettel and VinaPhone, provided that flows are compliant.
Fintech & Mobile Wallets
Digital finance adoption is growing fast:
- Mobile wallets
- Microloans
- Payment apps
These offers work best with educational or trust-based prelanders.
Mobile Gaming & Apps
Mobile gaming is massive in Vietnam.
- In-app purchases
- Game subscriptions
- App installs with monetization
Perfect match for social traffic and video ads.
E-commerce
Mobile e-commerce is mainstream:
- Fashion
- Beauty
- Gadgets
Works well with native content and retargeting.
5. Traffic Sources That Perform
Top traffic channels:
- TikTok Ads (short videos, strong engagement)
- Facebook and Instagram
- YouTube Shorts
- In-app traffic
- Push notifications
Local platforms like Zalo should not be ignored — they can outperform global channels for specific offers.
6. Carrier Billing & Subscriptions: Key Notes
Carrier billing is powerful in Vietnam, but only if:
- Pricing is clearly displayed
- Subscription terms are transparent
- Unsubscribe flow is simple
- Postbacks and tracking are clean
Operators actively monitor:
- Complaint rates
- Refund requests
- Fraud patterns
Poor-quality traffic gets shut down fast. Clean traffic scales. Dirty traffic dies.
7. Anti-Fraud & Technical Setup
Vietnam is not immune to:
- Click flooding
- Fake installs
- Incent traffic abuse
Affiliate Dragons recommendations:
- Use device fingerprinting
- Apply IP and UA filtering
- Monitor abnormal conversion spikes
- Track refunds and complaints, not only conversions
Long-term profit in Vietnam comes from traffic quality, not short-term spikes.
8. Actionable Recommendations for Affiliate Dragons
- Prioritize Viettel traffic for any mobile or billing-based offer.
- Always localize creatives and landing pages.
- Use short-form video as your main acquisition format.
- Combine carrier billing with local mobile wallets when possible.
- Build transparent funnels — Vietnam rewards trust.
- Invest in anti-fraud from day one.
- Optimize for LTV, not just first conversion.
Final Takeaway
Vietnam is a high-volume, mobile-driven affiliate GEO with massive upside for teams that understand telecom structure, user psychology, and local payment behavior.
For Affiliate Dragons, Vietnam should be treated as a strategic scaling GEO, not an experimental one. With the right operators, compliant subscription flows, and mobile-native creatives, this market can deliver stable revenue and long-term growth.
