SIXT.VN offers comprehensive travel solutions, ensuring seamless connectivity. This allows you to enjoy Vietnam’s beauty without communication hassles. Learn where to purchase, what to consider, and how to make the most of your mobile connectivity in Hai Duong.

1. Understanding Your Mobile Options in Vietnam

When traveling to Vietnam, you have several options for using your mobile phone. You can bring your locked phone and use international roaming, bring an unlocked phone and purchase a local SIM card, or buy a cheap phone locally.

• Locked Phone with International Roaming: Using international roaming can be convenient, but it is often the most expensive option. T-Mobile, for example, charges several dollars per minute and does not always offer mobile data. Check with your provider for rates and services.

• Unlocked Phone with a Local SIM Card: This is often the most cost-effective and flexible option. You can purchase a local SIM card and get a Vietnamese phone number. Make sure your phone is GSM-compatible. Smartphones are particularly useful as they can access 3G/4G networks with a data plan.

• Buy a Cheap Phone Locally: If your phone is not unlocked or GSM-compatible, you can buy a basic phone in Vietnam for local use. This can be a practical option for those who prefer not to use their primary device.

2. Where to Buy a SIM Card in Hai Duong City

Finding a local SIM card in Hai Duong City is straightforward. There are several convenient options available.

2.1. Mobile Carrier Stores

The most reliable way to purchase a SIM card is from official stores of major mobile carriers. In Vietnam, the primary carriers are Viettel, Mobifone, Vinaphone, Vietnammobile, and Gmobile. However, Viettel and Mobifone offer the best coverage and service quality, controlling about 90% of the market share.

You can find Viettel and Mobifone stores in central locations in Hai Duong City. These stores offer a variety of SIM cards and data packages. Staff can assist you in English, helping you choose the best option for your needs and ensuring the SIM card is properly installed and activated.

2.2. Mobile Phone Shops

In addition to carrier-specific stores, many mobile phone shops throughout Hai Duong City sell SIM cards from various providers. These shops often offer a range of services, including phone repairs and accessories, making them a convenient option for travelers.

2.3. General Stores and Tap Hoa

You can also find SIM cards at general stores and local grocery stores (Tap Hoa) throughout Hai Duong City. These establishments often display signs advertising Mobifone and Viettel SIM cards and top-up scratch cards.

However, buying from these smaller vendors can be riskier. There is a chance you might be sold an unregistered or expired SIM card. The vendor may not provide a refund or help with activation issues. The advantage is that you may not need to provide passport information for these “black market” SIM cards.

2.4. Airports and Border Crossings

While not directly in Hai Duong City, if you arrive in Vietnam through an international airport like Noi Bai in Hanoi or Tan Son Nhat in Ho Chi Minh City, you can buy a SIM card upon arrival. The airport kiosks offer a convenient option for immediate connectivity. From there, you can travel to Hai Duong City.

2.5. Considerations When Buying a SIM Card

• Passport Registration: Most official stores require you to provide passport information when purchasing a SIM card to comply with local regulations.
• Pre-paid Minutes and Expiration: Initial SIM cards come with pre-paid minutes and an expiration date. Choose a package that aligns with the length of your stay. For example, a 100,000 VND card may expire in 7 days, while a 200,000 VND card may last 30 days.
• Coverage: Stick with Viettel or Mobifone for the best coverage throughout Vietnam, including Hai Duong City.
• Assistance: Buy from official stores or reputable dealers for assistance with installation and activation.

3. Available SIM Card Packages and Data Plans

Mobile carriers in Vietnam offer a variety of packages tailored to different needs. Most travelers opt for SIM packages that include both local calling and data. Here are some popular options from Viettel and Mobifone:

3.1. Mobifone Packages

3.2. Viettel Packages

These packages provide a mix of data and call options. Consider your usage habits to select the best plan.

4. Setting Up 3G/4G on Your Phone

Once you have purchased a SIM card with a data plan, setting up 3G/4G is essential. Here’s how to do it.

• Automatic Configuration: In many cases, inserting the SIM card will automatically configure your phone. You may receive a configuration message that you need to accept.

• Manual Configuration: If the settings are not configured automatically, you may need to manually adjust your phone’s settings.

  • APN Settings:
    • Android: Go to Settings > Mobile Networks > Access Point Names. Add a new APN with the following settings:
      • Name: (Anything you like)
      • APN: (Check with your provider, usually “v-internet” for Viettel or “m3-world” for Mobifone)
      • Username: (Leave blank)
      • Password: (Leave blank)
    • iOS: Go to Settings > Cellular > Cellular Data Network. Enter the APN information in the Cellular Data and Personal Hotspot sections.

• Text Message Activation: Some carriers require you to send a text message to activate the data service. For example, you might need to send “4G ON” to a specific number like *888.

Contact the mobile carrier store for specific instructions.

5. Understanding Usage Rules and Adding Credit

1. Scratch the top-off card to reveal the 13-digit activation number.

   and press ‘Call’.
