With direct flights from Korea, China, Singapore, and Australia landing daily at Cam Ranh International Airport, connectivity is no longer a luxury — it’s a necessity. Whether you need maps to navigate, data to share photos, or reliable coverage during island tours, choosing the right SIM or eSIM matters. This pillar guide to nha trang sim card in 2025 provides a comprehensive breakdown of airport SIM kiosks, city shop SIMs, and the best eSIM alternatives, plus coverage checks, case studies, and practical tips.
✈️ Cam Ranh Airport SIM — Convenient but Expensive
For most visitors, the first chance to buy a SIM card is immediately after clearing immigration at Cam Ranh Airport. Major telecoms — Viettel, MobiFone, and VinaPhone — operate kiosks in the arrival hall.
- 15-day SIM: 450,000–500,000 VND (~$18–20), 2–3GB/day.
- 30-day SIM: 600,000–650,000 VND (~$24–26), 3–5GB/day + local calls.
- Payment: cash preferred; some accept cards with a 3% surcharge.
- Passport scan required for registration.
⚠️ Travelers should note: prices here are higher than city shops or eSIMs. The trade-off is convenience — kiosks are right at the exit, and staff will set up the SIM on your phone.

📊 Case Study 1 — Korean Tour Group at Cam Ranh
In January 2025, a group of six Korean travelers bought 30-day SIMs at Cam Ranh Airport (620,000 VND each, 3GB/day). Service worked in the city but dropped at Hon Mun. One traveler had prepared a Viettel eSIM ($18.50, 6GB/day) and remained connected. 👉 Their feedback: airport SIMs are fine for the city, but less reliable offshore.
💻 Case Study 2 — Freelancer in Bai Dai
A French freelancer stayed near Bai Dai beach for three weeks in November 2024. He used a city shop SIM (520,000 VND, 3GB/day, VinaPhone). Speeds averaged 40 Mbps in town, but dropped to 10 Mbps at Bai Dai. He then switched to a GoVnSIM eSIM ($14.50, 4GB/day, Viettel), which delivered 28–35 Mbps consistently along the coast. 👉 His conclusion: eSIMs offered steadier coverage for remote work outside the city.
