💵 SIM Price in Nha Trang 2025 — Real Costs, Coverage & eSIM Comparison
One of the first expenses travelers face on arrival in Nha Trang is buying a SIM card. But how much should you really expect to pay? This article looks at SIM price in Nha Trang across airport kiosks, city shops, and online eSIMs. We use updated 2025 price data, coverage tests, and case studies to give you a clear, realistic picture — helping you avoid overspending while staying connected.
✈️ SIM Prices at Cam Ranh Airport
Cam Ranh International Airport (CXR) is where most travelers first encounter SIM vendors. These kiosks sell Viettel, MobiFone, and VinaPhone packages at a premium price compared to pre-purchased eSIMs.
- 15-day SIM: 450,000–500,000 VND (~$18–20) with 2–3GB/day.
- 30-day SIM: 600,000–650,000 VND (~$24–26) with 3–5GB/day plus local calls.
- Payment: Cash is standard; some kiosks accept card with 3% surcharge.
Observation: Prices at the airport are 30% or more above online eSIM rates. Travelers pay for convenience and staff support, but at the cost of waiting in line and unclear terms.
🏙️ SIM Prices in Nha Trang City
In downtown Nha Trang (Tran Phu, Nguyen Thien Thuat streets), SIM shops and travel agencies resell tourist packages. These are cheaper than the airport but still 20–30% above online eSIM options.
- 15-day SIM: 400,000–450,000 VND (~$16–18) with 2GB/day.
- 30-day SIM: 500,000–550,000 VND (~$20–22) with local number and calls.
- Bonus: Some bundles include 30 minutes of free domestic calls.
✅ Advantage: more time to compare.
⚠️ Downside: risk of hidden activation fees or non-tourist SIMs with limited validity.
📱 eSIM Alternatives vs. Market Prices
eSIMs from GoVnSIM are priced more competitively, offering better value and clarity:
- Vietnam eSIM 20 Days — 4GB/day + local number: $14.50
- Vietnam eSIM 30 Days — 6GB/day + local number: $18.50
- Viettel eSIM 15/30 Days — 5GB/day (data only): $14.90–$19.90

📊 Cost Comparison Table

📊 Case Study 1 — Family Trip
In August 2024, a family of four from Australia compared options:
- Airport quote: 480,000 VND per SIM (~$19) for 15 days with 2GB/day.
- Pre-ordered 2 GoVnSIM eSIMs at $14.50 each (20 days, 4GB/day).
- Result: eSIMs gave double the daily data at ~25% less cost per SIM. Airport SIMs worked, but required 30 minutes waiting at the kiosk.
💻 Case Study 2 — Digital Nomad
A remote worker from Singapore stayed in Nha Trang for 3 weeks in October 2024:
- Bought a 30-day SIM in town: 520,000 VND (~$21), 3GB/day with calls.
- Later tried GoVnSIM eSIM: $18.50, 6GB/day. Speed averaged 55 Mbps in city cafés.
- Conclusion: eSIM offered more data and slightly lower cost. Both worked well, but eSIM saved him from having to register with a shop.
🌐 Speed Tests in Nha Trang (2024)
- Viettel: 50–70 Mbps in city, 20–30 Mbps on nearby islands.
- MobiFone: 40–60 Mbps in city, 15–20 Mbps offshore.
- VinaPhone: 30–50 Mbps in city, weaker along Bai Dai beaches.
For video calls and streaming, Viettel-backed eSIMs showed the most stable results.
🌊 Coastal Route Prices & Coverage
The 35 km route from Nha Trang city to Cam Ranh Airport is scenic but has patchy signal with some networks. Prices don’t change here, but coverage does:
- Viettel: almost continuous signal.
- MobiFone: occasional drops mid-route.
- VinaPhone: weakest along remote beaches.
Travelers renting scooters for this journey usually prefer Viettel despite slightly higher local shop prices, since coverage reliability is key.
