Question 3

Is eSIM better than a physical SIM card in Vietnam?

Accepted Answer

For most travellers, an eSIM is more convenient than a physical SIM card. It requires no delivery, no swaps, and works instantly on arrival. However, if you prefer traditional options, SimCorner also offers Vietnam prepaid SIM cards alongside eSIM plans.

Accepted Answer

At SimCorner, an eSIM card for Vietnam can start from as low as AU$5, depending on the data allowance and duration. We offer a range of affordable prepaid eSIM plans, including data-only, unlimited data, and global options, so you can choose the plan that best suits your budget.

Question 5

How do I activate my eSIM Vietnam?

Accepted Answer

To activate your eSIM Vietnam, purchase a plan from SimCorner, receive the QR code by email, and scan it with your eSIM-compatible phone. Activation usually takes a few minutes. Once installed, you can switch between your home SIM and your Vietnam eSIM from your phone settings.

Question 6

When should I activate my eSIM card for Vietnam?

Accepted Answer

You can install your eSIM Vietnam before your trip to make setup easier while still on your home network. In most cases, however, it’s best to activate it only after arriving in Vietnam to maximise the plan’s validity period. SimCorner plans begin once the eSIM connects to a local Vietnamese network.

Question 7

Can I keep my original number while using a Vietnam eSIM?

Accepted Answer

Yes, you can keep your original number for calls and messages while using the Vietnam eSIM for mobile data, provided your device allows dual SIM functionality. If it doesn’t support a dual SIM setup, your phone number will be changed. This is ideal for staying in touch with family while avoiding expensive roaming charges.

Question 8

Do I need internet or Wi-Fi to activate my eSIM Vietnam?

Accepted Answer

Yes, you’ll need an internet or Wi-Fi connection to initially download and install the eSIM profile. You can activate it using Wi-Fi at the airport, your hotel, or any hotspot. Once activated, the eSIM connects automatically to local networks.

Question 9

Do Vietnam eSIMs include calls and SMS?

Accepted Answer

Our Vietnam eSIMs are designed for data-only use and do not include calls or SMS. If you need voice services, you can use apps like WhatsApp, Viber, or Skype over data. Choose from fixed-data or unlimited plans depending on how much connectivity you’ll need during your trip.

Question 10

How long are Vietnam travel eSIM plans valid?

Accepted Answer

Vietnam travel eSIM plans are flexible, with validity periods ranging from 5 to 90 days. Short-term travellers can choose smaller data packs, while long-term visitors, expats, or digital nomads may prefer unlimited or extended plans for continuous coverage.

Question 11

Can I top up or extend my Vietnam eSIM plan?

Accepted Answer

Currently, SimCorner prepaid Vietnam eSIMs cannot be topped up directly. If you need more data or validity, you can purchase another eSIM plan and activate it once your current plan expires. This ensures you’re always connected.

Question 12

Can I use my Vietnam travel eSIM in other countries?

Accepted Answer

No, you cannot use your Vietnam travel eSIM in other countries. If you’re visiting multiple destinations, we recommend choosing a regional Asia eSIM or a global eSIM plan. With this,  you can stay connected across different countries with just one activation, avoiding the need for separate eSIMs.

Question 13

How good is eSIM coverage in Vietnam?

Accepted Answer

Our eSIM coverage in Vietnam is excellent in major cities like Hue, Ho Chi Minh City, and Sapa, with reliable 4G/5G service. Speeds and coverage in rural or remote areas are generally good, but they may vary depending on location and local network availability.

Question 14

Which networks do SimCorner eSIM Vietnam use?

Accepted Answer

SimCorner Vietnam eSIMs connect to leading local providers such as Viettel and Vinaphone, ensuring strong coverage and fast speeds. This allows travellers to enjoy reliable internet for browsing, maps, and video calls throughout the country.

Will my Vietnam eSIM work at tourist spots?

Yes, Vietnam eSIMs work at popular tourist destinations, including Ha Long Bay, Hoi An, Phu Quoc, Ha Long Bay, and the Mekong Delta. You can rely on strong connectivity for navigation, booking rides, and sharing travel updates across social media.

Question 16

Is 5G available with eSIM Vietnam plans?

Accepted Answer

Yes, most SimCorner Vietnam eSIMs support 5G where networks are available. In major cities, you can enjoy fast 5G speeds, while in smaller towns or rural areas, service might switch to 4G LTE or 3G.

Question 17

Which phones support eSIM for Vietnam?

Accepted Answer

Popular models like iPhone XS or later, Google Pixel 4 and newer, plus select Huawei and Oppo phones support eSIM for Vietnam. However, always ensure your device is unlocked and eSIM-compatible before you buy your plan, and you’ll be ready to connect instantly.

Question 18

How can I check if my phone is eSIM-compatible?

Accepted Answer

Check your phone settings: on iPhone, go to Settings > Cellular > Add Cellular Plan. If the option appears, your device supports eSIM. On Android, look under Settings > Connections > SIM Manager. You can also check the “Device Compatibility” option provided at the upper right side of each of our eSIM Vietnam plans.

Question 19

Can I use my Vietnam eSIM on multiple devices?

Accepted Answer

No, once an eSIM QR code is scanned and installed on one device, it cannot be reused on another. Each Vietnam eSIM is designed for single-device use; however, you can switch between different profiles. If you need multiple devices connected, purchase separate plans.

Question 20

Do tablets and smartwatches support eSIM Vietnam?

Accepted Answer

Yes, many eSIM-enabled tablets, including iPad Pro and iPad Air (3rd generation or later), as well as select smartwatches, support Vietnam eSIMs for data use. Calling features are not always available on wearables, so confirm compatibility before purchase.
