Vietnam SIM Card: Viettel, Vinaphone & Mobifone — Plans, Prices & Where to Buy

For travelers visiting Vietnam, reliable mobile connectivity is often a top priority. A local SIM card or an eSIM can provide a cost-effective and secure way to stay online, offering a significant advantage over international roaming or public Wi-Fi networks. This guide aims to provide a comprehensive overview of your options, detailing the types of SIM cards available, their typical costs, where to purchase them, and a comparison of Vietnam's leading mobile operators: Viettel, Vinaphone, and MobiFone.

Generally, for most tourists, a prepaid Viettel SIM or an eSIM is considered a strong choice due to Viettel's extensive coverage and competitive pricing. When opting for an eSIM purchased online, passport registration is typically not required, streamlining the setup process. Expect to find tourist plans ranging from approximately 60,000 to 180,000 Vietnamese Dong (around $2.50–$7 USD) for durations between 7 and 30 days, though prices and availability can change.

Quick Comparison: Physical SIM vs. eSIM for Vietnam

Understanding the differences between physical SIM cards and eSIMs is key to choosing the right option for your travel needs. The table below outlines some primary distinctions:

Why a Local SIM Card is Essential for Travel in Vietnam

While free Wi-Fi is available in many hotels, cafes, and restaurants across Vietnam, its reliability can be inconsistent, especially when traveling between cities or outside major tourist hubs. Public Wi-Fi networks also pose potential security risks due to their shared nature. A local SIM card or eSIM offers several practical advantages for tourists:

• Reliable 4G/5G Data: Enjoy consistent internet access wherever you go, supporting navigation, communication, and online research.
• Seamless App Usage: Maintain uninterrupted access to essential travel apps like Grab (for ride-hailing), Google Maps (for navigation), and Zalo (a popular local messaging app).
• Cost-Effectiveness: Local data plans are significantly more affordable than international roaming services, which can cost $10–$12 per day with many home carriers.

The only scenario where a local SIM might not be necessary is for very short layovers where airport Wi-Fi is sufficient for your needs.

Understanding Your Options: Types of Vietnam SIM Cards

When selecting a mobile connectivity solution for your trip to Vietnam, it's helpful to understand the different types of SIM cards available based on their form, function, and flexibility.

Physical SIM vs. eSIM

• Physical SIM: This is the traditional plastic card that you insert into your phone's SIM card slot. Physical SIMs are readily available at airports, official carrier stores, and various phone shops throughout Vietnam. A key requirement for purchasing a physical SIM is passport registration, which is a standard procedure in the country.
• eSIM (Embedded SIM): An eSIM is a digital SIM that is installed onto your phone via a QR code or through your device's settings. It eliminates the need for a physical card and, when purchased from online eSIM providers, often does not require passport registration. However, it is essential that your phone is unlocked and eSIM-compatible to use this technology.

Data-Only vs. Data + Voice/Text

• Data-Only Plans: These plans provide internet access for all online activities, including using navigation apps, ride-hailing services (with an existing account), messaging apps like WhatsApp, and social media. Data-only plans typically offer the best value for most tourists who primarily rely on internet-based communication.
• Data + Vietnamese Number Plans: These plans include a local Vietnamese phone number, allowing for incoming and outgoing calls and SMS messages within Vietnam. This option is particularly useful if you need to register for local services like Grab, receive one-time password (OTP) codes for online transactions, or make calls to local businesses or contacts.

Prepaid vs. Postpaid

• Prepaid Plans: For tourists, prepaid plans are the only practical option. You pay for your service upfront, with no contract or local address required. These plans offer flexibility and are designed for short-term use.
• Postpaid Plans: Postpaid plans typically require a local address, a Vietnamese bank account, and a credit check. These are not suitable for visitors or short-term travelers.

General Cost Overview for Vietnam SIM Cards

The cost of a Vietnam SIM card can vary depending on the type of SIM, the provider, and the duration and data allowance of the plan. It's important to note that prices and availability can change, so it's always advisable to check current offers upon arrival or before purchase.

• Physical SIM Cards (from airport or carrier stores): Tourist plans covering 7 to 30 days typically range from 60,000–199,000₫ (approximately $2.50–$8 USD).
• MobiFone Hi Vietnam App: This unique offering provides a free eSIM with 8GB data and 10 minutes of local calls for the first 24 hours upon registration. Subsequent paid plans for 3–30 days range from 80,000–240,000₫ (approximately $3.20–$9.60 USD) and can be paid for in-app using Visa or Mastercard.
• eSIM Plans from Online Providers: Prices for eSIM plans from online providers can start from around $1.13 USD for a 1-day plan with 500MB/day, or $2.94 USD for a 3-day unlimited data plan (based on NexaEsim catalog as of 2026-09-19). While potentially higher than some physical SIMs, these offer the convenience of no passport registration, no queues, and the ability to purchase before you travel.
• International Roaming (from your home carrier): This is generally the most expensive option, often costing $10–$12 per day for comparable data allowances from major international carriers.

Major Mobile Operators and Their Tourist SIM Offerings

Vietnam's mobile market is dominated by three main operators: Viettel, Vinaphone, and MobiFone. Each offers tourist-friendly SIM plans with varying strengths in coverage and features.

Viettel – Broadest Coverage and Strong Performance

Viettel is Vietnam's largest mobile carrier, holding a significant market share. It is renowned for having the most extensive national coverage, with 4G reaching 98.6% of the population and 5G covering 91.2%. This makes Viettel an excellent choice if your travel plans include exploring areas outside major cities or more remote regions.

Some representative Viettel tourist SIM plans, as observed in the source material, include:

• 5G60T: 7 days validity, 5GB/day data, no calls, priced at 60,000₫ (approximately $2.50 USD).

Note: 'On-net' calls refer to calls made to other Viettel numbers, while 'off-net' calls are to other Vietnamese networks. The prices listed above do not include the cost of the physical SIM card itself, which may be an additional fee. For physical SIM purchases, passport registration is required at Viettel airport counters or authorized stores. You can find Viettel counters with distinctive red-and-white branding and bilingual pricing boards at major airports such as Noi Bai (Hanoi), Tan Son Nhat (Ho Chi Minh City), Da Nang, Cam Ranh (Nha Trang), and Phu Quoc. For more detailed information, consider our Viettel Tourist SIM Card Guide.

Vinaphone – Strong in Cities, Offers Local Numbers

As Vietnam's second-largest carrier, Vinaphone offers mobile speeds comparable to Viettel within urban areas. Vinaphone plans can be particularly beneficial if you require a local Vietnamese phone number for purposes such as Grab registration, receiving OTP verifications, or making local calls.

A representative Vinaphone tourist SIM plan, as observed in the source material, includes:

• Plan Details: 15 days validity, 1GB/day data, 50 minutes local calls + 50 minutes international calls, 50 free SMS, priced at 199,000₫. This plan also includes a 10,000₫ main balance credit. International calls are available to countries such as the US, Canada, China, Hong Kong, Singapore, UK, Australia, France, Germany, and Japan, typically accessed via the prefix 1714.

It is important to note that Vinaphone's network coverage may be less robust in mountainous and remote rural areas compared to Viettel. Physical Vinaphone tourist SIMs are typically automatically deactivated after 15 days. For more details, refer to our Vinaphone Tourist SIM Card Guide.

MobiFone – The Hi Vietnam App Approach

MobiFone distinguishes itself with the

Where to Buy Physical SIM Cards in Vietnamese Cities

Beyond airport kiosks, travelers can find physical SIM cards at various locations within Vietnamese cities. These options often provide more choices and potentially better prices than airport vendors.

Official Carrier Stores

For the most reliable service and assistance, purchasing a SIM card directly from an official carrier store is recommended. Staff at these stores often have some English proficiency, which can be helpful during the registration process. You can find official stores for:

• Viettel: Check their official website for store locations.
• Vinaphone: Their website provides a list of transaction points.
• MobiFone: Store locations are available on their customer support page.

Phone Retail Chains

Major phone retail chains across Vietnam also stock SIM cards from all primary networks. These include:

• The Gioi Di Dong
• FPT Shop
• CellphoneS

When purchasing a physical SIM card, it is generally advisable to research your preferred plan in advance and ask for it by name. This approach can help ensure you receive the correct plan at the advertised price and avoid potential upsells. Be cautious of unmarked street stalls or unofficial vendors, as SIM card scams can occur, particularly in tourist-heavy areas.

Choosing Your Data Plan: How Much Data Do You Need?

Understanding your typical data usage can help you select the most suitable plan for your trip to Vietnam. Here's a general guide:

• Light Usage (maps, messaging, email): 1–3 GB per week
• Moderate Usage (social media, GPS, travel apps): 3–5 GB per week
• Heavy Usage (video calls, streaming): 10–15 GB per week
• Digital Nomad (remote work): An unlimited data plan may be more appropriate.

For a typical 1–2 week tourist trip with moderate internet use, a plan offering 5–10 GB of total data should generally be sufficient. If you are unsure about your exact data needs, opting for a plan with a slightly higher allowance can prevent the inconvenience of running out of data mid-trip.

Activating and Using Your Vietnam SIM or eSIM

Activating Your SIM or eSIM

• Physical SIM Card: If you purchase a physical SIM card at the airport, staff will typically activate it for you. If you are activating it yourself, follow the instructions provided on the SIM card packaging, which usually involves sending a specific text message to a designated number.
• eSIM: For eSIMs purchased from online providers, activation is generally automatic. The eSIM will connect to the local Vietnamese network upon your arrival and first network connection, requiring no additional action from your side. For a comprehensive guide, refer to our article on How to Install & Activate an eSIM in Vietnam.

Checking Data Balance and Topping Up

Once your SIM is active, you may need to check your remaining data or add more credit:

• Viettel: Send an SMS with the text “KTTK” to 191.
• Vinaphone: Dial *101# from your phone.
• MobiFone: Dial 0905# from your phone.

To top up a physical SIM card, you can purchase scratch cards from phone shops and convenience stores, or use online banking applications such as MoMo and ZaloPay.

Frequently Asked Questions

Can a tourist buy a SIM card in Vietnam?

Yes, tourists can purchase SIM cards in Vietnam. For physical SIM cards, passport registration is a requirement. However, many eSIM plans available from online providers do not require ID registration, only an eSIM-compatible, unlocked phone.

Which SIM card is best for tourists in Vietnam?

The best choice depends on your travel needs:

• Viettel is often recommended for its extensive network coverage across the country.
• Vinaphone can be a good option if you specifically require a local Vietnamese phone number.
• MobiFone might be suitable if you plan to stay primarily in major cities and are working with a tighter budget.

For a more detailed comparison, see our guide on Vietnam Mobile Operators: Viettel vs Vinaphone vs MobiFone.

Can I buy a SIM card at Vietnam airport?

Yes, you can purchase SIM cards at major Vietnamese airports. Viettel and Vinaphone typically have counters at Noi Bai (Hanoi), Tan Son Nhat (Ho Chi Minh City), Da Nang, and Cam Ranh (Nha Trang) airports. Remember to bring your passport for registration. Be aware that counters may have limited hours and could be closed for very late arrivals.

Does a Vietnam SIM card come with a phone number?

Physical SIM cards purchased in Vietnam generally include a local phone number. For eSIM plans, this varies by provider and plan. Some eSIMs, like certain Viettel eSIMs, are data-only and do not include a local number. Other eSIMs, such as many Vinaphone and MobiFone eSIM plans, do include a local phone number.

What’s the difference between a SIM card and eSIM in Vietnam?

The primary difference lies in their physical form and activation. A physical SIM card is a tangible chip inserted into your phone, requiring manual installation and often in-person registration. An eSIM is embedded digitally in your device, allowing for remote activation and management without a physical card. For a full comparison, please refer to our guide on Vietnam eSIM vs Physical SIM Card.

Do I need a Vietnamese phone number as a tourist?

Whether you need a Vietnamese phone number depends on your specific needs during your trip. A local number can be useful for making local calls, receiving SMS messages, or using certain local apps that require a Vietnamese number for registration. However, for most tourists primarily needing data for navigation, messaging, and internet access, a data-only plan may suffice. Consider your communication habits and local service requirements to decide if a local number is essential for you.
