📑 Why Connectivity Matters for Cruise Passengers

While ships usually offer WiFi packages, costs are high (often US$15–30/day per device) and coverage ends at sea. Once you dock, you need reliable internet for Google Maps, Grab rides, messaging, and OTP services. For shore excursions lasting only 6–12 hours, the choice between cruise WiFi, local SIMs, and prepaid eSIMs becomes crucial.

🛳️ Cruise Ship WiFi

Most cruise lines (Royal Caribbean, Princess, MSC) sell onboard WiFi passes. These use satellite connections:

• Cost: US$15–30 per device/day.
• Coverage: Works at sea, but slower near land due to congestion.
• Limitations: Often capped for streaming or video calls.

Once you disembark, cruise WiFi no longer works, forcing travelers to switch to mobile internet onshore.

📦 Pocket WiFi Rentals for Shore Days

Some agencies advertise Pocket WiFi rentals for cruise passengers. But this involves:

• Pre-arranging delivery at the port.
• Paying daily fees (≈120,000–180,000₫ or US$5–7).
• Leaving a deposit of ~US$80–120.
• Returning before re-boarding — risky with tight shore schedules.

Airport and city shops typically charge 30–40% more than prepaid eSIM totals. For shore excursions, the pickup and return hassle can outweigh the benefits.

💌 Prepaid eSIM for Shore Excursions

Prepaid eSIMs are increasingly popular for cruise travelers. Delivered instantly via QR code, they activate before you even leave the ship. Key benefits:

• ✅ No pickup/return — just scan QR and go.
• ✅ Valid for 10–30 days (covering all ports in Vietnam).
• ✅ Costs US$8.50–19.50, far cheaper than cruise WiFi or Pocket WiFi.
• ✅ Supports tethering to laptops or tablets.

Airport SIM shops also charge ~40% more than prepaid eSIMs. For short port calls, prepaid eSIMs remain the most efficient.

🧭 Traveler Story: Ha Long Bay Port Call

Emma from Australia docked at Ha Long Bay for 8 hours. She relied on cruise WiFi (US$18/day), but once ashore, it stopped working. Without data, she couldn’t book a Grab. Another traveler in her group used a prepaid eSIM (US$12.50 for 15 days) and was online immediately, guiding the group to restaurants and attractions without delay.

🧭 Traveler Story: Day Trip in Da Nang

John from the US had a one-day shore trip in Da Nang. He rented a Pocket WiFi from a local shop. By the time he cleared port customs and picked it up, he had lost nearly an hour. Returning it before boarding was stressful. Meanwhile, another passenger activated a prepaid eSIM before docking, paying ~US$9, and enjoyed seamless data throughout.
