📱 Best eSIM in Nha Trang 2025 — Prices, Coverage & Real Travel Insights
Nha Trang is one of Vietnam’s most visited coastal cities, attracting millions of tourists every year. Staying connected is essential whether you’re exploring the city, island-hopping, or commuting to Cam Ranh Airport. This article breaks down the best eSIM Nha Trang options in 2025, comparing them with airport SIMs and city shops, including real case studies, speed tests, and practical tips.
✈️ Airport SIM Prices vs. eSIMs
At Cam Ranh International Airport (CXR), kiosks offer Viettel, MobiFone, and VinaPhone SIM cards at premium tourist rates:
- 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 and local calls.
- Passport scan required, cash preferred, queues during peak arrivals.
These rates are at least 25–30% higher than online eSIM plans, while offering less daily data. Travelers pay for immediate staff assistance, but with less transparency.
🏙️ City SIM Shop Prices
Shops around Tran Phu, Nguyen Thien Thuat, and tourist zones sell tourist SIMs at slightly lower prices than the airport:
- 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.
- Some include bonus local calls, but hidden activation fees are common.
While more affordable than airport kiosks, city shop SIMs still cost 20–25% more than eSIM options purchased online.
📶 Best eSIM Options for Nha Trang 2025
For travelers seeking clarity, flexibility, and value, GoVnSIM’s eSIM packages stand out:
- 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
These plans are cheaper and provide more data compared to market SIMs, while avoiding queues or paperwork. Activation is automatic, making them ideal for those landing at Cam Ranh late at night or during peak hours.
🌐 Coverage in Nha Trang & Islands
Based on speed tests and coverage checks in late 2024, here’s how networks compare:
- Viettel: Strongest in city, Bai Dai coastal road, and offshore islands like Hon Tam and Hon Tre.
- MobiFone: Reliable in city and near popular beaches, weaker mid-route to Cam Ranh.
- VinaPhone: Acceptable in city center, but drops more often offshore.
Travelers taking boat tours or commuting to Cam Ranh Airport will find Viettel-backed eSIMs most consistent.
📊 Cost Comparison Table
| Option | 15 Days | 30 Days | Notes |

📊 Case Study 1 — Couple on a Beach Holiday
In September 2024, a couple from South Korea spent 10 days in Nha Trang:
- They bought a 15-day SIM at the airport: 480,000 VND (~$19) with 2GB/day.
- They also pre-ordered a GoVnSIM 20-day eSIM: $14.50 with 4GB/day.
- Result: The eSIM had double the daily data at a lower cost. Airport SIM worked but required 30 minutes waiting in line.
💻 Case Study 2 — Remote Worker
A digital nomad from France worked from Nha Trang in November 2024:
- Bought a 30-day SIM in the city: 520,000 VND (~$21) with 3GB/day.
- Later switched to GoVnSIM 30-day eSIM: $18.50 with 6GB/day.
- Speed test: SIM averaged 40 Mbps; eSIM (Viettel network) averaged 55 Mbps. The eSIM was cheaper and more reliable for video calls.
🚤 Internet on Island Tours
Island-hopping tours are a highlight in Nha Trang. Signal performance varies:
- Viettel: 4G available near Hon Tre and Vinpearl complex, usable at Hon Tam.
- MobiFone: fine nearshore, drops completely further out.
- VinaPhone: weaker offshore, often falls back to 3G.
For travelers who want to upload photos or navigate, Viettel-backed eSIMs are the safest option offshore.
📌 Practical Tips for Getting the Best eSIM in Nha Trang
- ✅ Buy your eSIM before departure to skip queues at the airport.
- ✅ Choose a plan with at least 4GB/day if you stream or work remotely.
- ⚠️ Avoid small street vendors selling “tourist SIMs” — often unreliable.
- 📲 Keep offline maps as backup for coastal rides.
- 💡 Carry a power bank, as GPS + hotspot drains battery quickly.
