Duong Dong SIM Shops 2025 Guide
Many travelers in Phu Quoc ask where to buy affordable mobile data. Duong Dong town is the busiest hub for this, with plenty of telecom outlets. This 2025 guide covers Duong Dong SIM shops, real local prices, their limitations, and how they compare to online eSIM options. For the full breakdown, see the Phu Quoc SIM & eSIM pillar guide.
🏙️ Why Duong Dong SIM Shops Are Popular
Duong Dong is Phu Quoc’s main town, home to markets, hotels, and official Viettel, MobiFone, and VinaPhone outlets. Prices here are usually lower than airport kiosks, but still come with important limitations travelers should know about.
📊 Real SIM Prices in Duong Dong (2025)
These are typical rates at Duong Dong SIM shops in 2025, converted into USD for easier comparison:
| Provider | Plan Example | Data | Validity | Price (USD) | Limitations |
|---|---|---|---|---|---|
| Viettel | Tourist SIM Basic | 10GB (fixed) | 15 days | $8 – $10 | Low data cap, requires passport |
| MobiFone | Tourist SIM Standard | 15GB (fixed) | 30 days | $12 – $15 | No daily reset, possible top-up hassles |
| VinaPhone | Tourist SIM Plus | 20GB (fixed) | 30 days | $16 – $22 | Runs out fast if streaming; paperwork needed |
All physical SIMs in Vietnam require passport registration. Most are capped at 10–20GB total, meaning heavy users may need to top up mid-trip.

| Vietnam eSIM with Phone Number | MobiFone / VinaPhone | 3–5GB/day | 10 / 15 / 30 days | $8.50 – $19.50 | Local number included |
Unlike fixed-data SIMs, these eSIMs provide daily allowances, often adding up to 100–150GB per month.
🛬 Airport vs Duong Dong Shops
Airport kiosks typically charge $20–$25 for 10–15GB valid 10–15 days. In Duong Dong, the same plan costs $8–$15. However, both require a passport and only offer fixed data. By comparison, pre-ordered eSIMs deliver more data and remove the need to queue.
🌐 Coverage & Speed
Based on 2025 field tests:
- Duong Dong town: 35–45 Mbps (stable)
- Long Beach: 30–40 Mbps
- Outskirts: 15–25 Mbps
Viettel leads in rural coverage, while MobiFone and VinaPhone work well in central Phu Quoc.
🧳 Case Study
Marco from Italy bought a Viettel SIM in Duong Dong for $10 (10GB/15 days). It worked fine at first, but he ran out of data on day 12. His partner used a MobiFone eSIM (4GB/day for $14.50) and had reliable internet every day of their trip without topping up. The difference highlighted the long-term value of eSIM.
