Vietnam has become one of the most popular travel destinations in Southeast Asia.
Tourists visiting cities such as Hanoi, Ho Chi Minh City, and Da Nang rely heavily on mobile internet for navigation, ride-hailing apps, translation tools, and travel bookings.
Fortunately, travelers in Vietnam have several ways to access mobile data.
The most common options include:
- International roaming
- Local prepaid SIM cards
- Pocket WiFi devices
- Travel eSIM plans
In this guide, we explain how tourists can get internet in Vietnam, typical mobile data costs, and which option is the most convenient for travelers.
1. Using eSIM in Vietnam
One of the easiest ways to get internet in Vietnam is installing a travel eSIM before your trip.
An eSIM is a digital SIM card that can be activated directly on your smartphone without inserting a physical SIM.
If you’re unfamiliar with the technology, read our guide explaining how eSIM works.
Advantages of using eSIM include:
- Activation before travel
- Instant internet after landing
- No need to visit local stores
- Keeping your primary SIM active
Travelers can explore Vietnam eSIM plans for quick connectivity during their trip.
2. Buying a Local SIM Card in Vietnam
Local prepaid SIM cards are widely available and inexpensive.
The main mobile operators in Vietnam include:
- Viettel
- Mobifone
- Vietnamobile
Tourist SIM cards usually include:
- Large mobile data packages
- Local calls
- Validity between 7 and 30 days
SIM cards can be purchased in:
- Airports
- Mobile operator stores
- Convenience shops
3. Using Pocket WiFi
Some travelers choose to rent Pocket WiFi routers.
These portable routers create a personal WiFi hotspot that multiple devices can connect to.
Pocket WiFi can be useful for:
- Families traveling together
- Groups sharing internet access
However, renting Pocket WiFi requires carrying and charging an additional device.
Because of this, many travelers now prefer using eSIM.
4. Using International Roaming
Travelers can also use international roaming provided by their home carrier.
Roaming allows your phone to connect to Vietnamese mobile networks automatically.
However, roaming charges can be high depending on your mobile operator.
For this reason, most tourists choose local SIM cards or travel eSIM plans instead.
