SIM or eSIM: Which one should you choose?
Choose eSIM if your phone supports eSIM and is unlocked. It is convenient because there is no plastic card, and you can keep your home SIM in the phone.
Choose physical SIM if your phone does not support eSIM, if you want a simple local phone number, or if you prefer setup assistance after arriving in Vietnam.

Passport may be needed
5G where available
Hotspot depends on plan
Before you arrive in Vietnam
Check that your phone is not carrier-locked. For eSIM, check that your exact model supports eSIM and that you still have a free eSIM slot. For physical SIM registration, keep your passport ready because carrier registration can be required for traveler SIM activation.
If your itinerary includes airport pickup, hotel transfer or tours, ask the support team to match the SIM/eSIM setup with your arrival time so you can use maps, ride-hailing apps and messaging immediately.
How to activate your Vietnam SIM/eSIM
1Choose packagePick data-only or data + call based on trip length, phone compatibility and local call needs.
2Prepare phoneUse an unlocked device. For eSIM, keep Wi-Fi available to scan the QR or activation code.
3Install and testInsert SIM or add eSIM, turn on mobile data, then test Google Maps, WhatsApp and browser access.
4Get supportIf signal or data does not work, contact Ocean Treasure Travel with phone model, package and location.
Common questions from foreign travelers
Do I need a passport to buy a SIM in Vietnam?
For a physical local SIM, passport information may be needed for carrier registration. This helps keep the SIM valid and reduces the risk of service interruption.
Can I use Google Maps, Grab, WhatsApp and translation apps?
Yes. These are the main reasons travelers buy a Vietnam SIM/eSIM. Choose enough high-speed data if you use video calls, social media uploads or hotspot sharing.
Does eSIM work on every phone?
No. Your phone must support eSIM and must be unlocked. Many recent iPhone, Samsung Galaxy, Google Pixel and some other models support eSIM, but always check your exact model first.
What should I do if mobile data does not work?
Restart the phone, check that mobile data is enabled, choose the new SIM/eSIM for data, check APN settings if needed, and make sure your phone is not locked to another carrier.
Can I share hotspot with my laptop or family?
Usually yes, but hotspot availability can depend on the selected package and device settings. Tell the consultant if you plan to share data with several devices.
Can the package be topped up after 30 days?
Some data + call packages allow monthly top-up and longer-term use. Confirm the exact package before purchase if you plan to stay in Vietnam longer.
Which network is best for Vietnam travel?
Viettel is often preferred for broad coverage, while Vinaphone and Mobi local can be strong choices depending on city, travel route and call/data needs.
Can I arrange SIM/eSIM together with airport pickup?
Yes. If you book airport pickup, private car or tours with Ocean Treasure Travel, ask the consultant to coordinate SIM/eSIM support with your arrival details.
Best use cases
For a 3-5 day city trip in Ho Chi Minh City, Da Nang or Hanoi, the 15-day data SIM is usually enough. For a 2-4 week Vietnam itinerary, choose a 30-day SIM/eSIM. For business travelers, tour leaders, expats or guests who need local calls, choose the data + call option.
The most important rule is simple: match the package to your phone, travel length, language support and whether you need a Vietnamese phone number.
Need help choosing the right Vietnam SIM or eSIM?
Send your arrival date, phone model, travel length and whether you need calls. Ocean Treasure Travel will suggest the most suitable package in VND.
