Vietnam eSIM Samsung Galaxy S24: Install in 60 Seconds

Yes — the Samsung Galaxy S24, S24+, and S24 Ultra all support eSIM natively. This includes US, EU, Korean, Japanese, and most global variants (the only exceptions are devices sold in mainland China, Hong Kong, and Macau, which lack eSIM hardware). If you have a compatible unit, you can install a Vietnam eSIM in roughly 60 seconds using a QR code.

A Vietnam eSIM from our store works with major local carriers — Viettel, Vinaphone, or Mobifone. Viettel is the largest network with coverage in nearly all provinces, while Vinaphone offers competitive urban speeds. The eSIM can be installed before you depart; it activates automatically once the phone connects to a Vietnamese network. No need to remove your physical SIM.

Before purchasing, confirm your device supports eSIM. Go to Settings > About phone > Status > SIM card status. If you see an IMEI number (not just MEID or ESN), your phone has eSIM hardware. All Galaxy S24, S24+, and S24 Ultra models sold outside mainland China, Hong Kong, and Macau include eSIM — including US carrier-unlocked and carrier-locked units (though carrier-locked devices may still require an unlocked SIM slot for the eSIM).

If you own a dual physical SIM variant (common in some Asian markets), you can still add one eSIM alongside one physical SIM. That gives you two active lines: your home SIM for calls/SMS and the eSIM for data. The S24 allows up to two eSIM profiles stored at once, but only one eSIM can be active at a time.

Purchase a Vietnam eSIM from our store: select your carrier (we recommend Viettel for the widest rural coverage, but Vinaphone and Mobifone are also good for city-focused trips) and choose a plan that fits your stay. Available data plans include 5 GB/day for 7, 15, or 30 days at prices from $10–$15, depending on duration and carrier.

After checkout, you will receive an email with a QR code and an SM-DP+ address. Check your spam folder if it doesn't appear within a few minutes. The QR code is single-use — once scanned and downloaded, it cannot be reused. Do not share or screenshot the code; each code is tied to one device.

Start by connecting to a Wi-Fi network — the eSIM download requires an internet connection. Open Settings > Connections > SIM card manager > Add eSIM. Tap 'Scan QR code' and point your camera at the QR code from the email. If your phone does not scan immediately, adjust the distance or brightness of the screen showing the code.

Follow the on-screen prompts to confirm the download. When asked, assign a label like 'Vietnam Data' so you can easily identify it later. After installation, go back to SIM card manager and set the eSIM as your default line for mobile data (you can keep your home SIM for voice and SMS). Once you land in Vietnam, the eSIM will automatically detect and register on the network. If it doesn't connect after a few minutes, try rebooting your phone. Total time from QR to active: around 60 seconds.

If the QR code won't scan, switch to manual entry: in the 'Add eSIM' screen, select 'Enter code manually' and type the SM-DP+ address and activation code from your email. If the eSIM profile fails to download altogether, contact our support within 24 hours for a replacement QR code.

Once in Vietnam, if you have no data, go to Settings > Connections > Mobile networks > Network operators and select 'Viettel', 'Vinaphone', or 'Mobifone' manually — the phone may not auto-select the correct network. Also ensure that data roaming is turned ON specifically for the eSIM line (in SIM card manager). Your home physical SIM remains active; you can switch to the eSIM for data without removing it.

You can keep your home physical SIM active for calls and SMS while using the eSIM exclusively for mobile data. In SIM card manager, set the eSIM as 'Primary data line'. Your home SIM can be set as 'Primary voice line' — calls and texts still go through as usual. Be aware that making or receiving calls on your home SIM while roaming may incur high international charges; for voice calls, use VoIP apps like WhatsApp, Telegram, or FaceTime over the eSIM data.

On the Galaxy S24, you can configure which line handles calls, messages, and data independently. This is especially useful if you need to receive SMS from your home bank or two-factor authentication while using Vietnamese data. Just remember that any data consumed by background services on your home SIM while roaming could lead to unexpected fees — to be safe, turn off 'Allow data while roaming' for your home SIM in the SIM card manager.
