An eSIM is a built-in digital SIM that lets you connect to mobile networks without inserting a physical card. It works just like a regular SIM and is embedded in devices like phones, tablets, and wearables.
Once your payment is confirmed, your eSIM QR code will be sent to your email. You can scan and activate it before your trip or when you arrive in Vietnam.
3–4GB is typically sufficient for browsing, maps, and messaging. For streaming or longer stays, choose a plan with more data. Use free Wi-Fi when possible to conserve data.
Your plan starts when you activate your eSIM—not when you scan the QR code. Activation begins manually from your phone settings.
No, your WhatsApp number and data will remain intact. You can continue using it normally after switching to the eSIM.
The Vietnam eSIM connects to Vinaphone, a major network offering fast speeds and wide coverage. It delivers great performance both in cities and rural areas.
Yes, enabling data roaming is essential for the eSIM to function properly. It won’t incur extra charges as long as you're using your purchased plan.
After you consume all your data or the validity ends, your eSIM will stop working. You’ll need to buy a new plan to reconnect to the internet.
We recommend installing your eSIM before departure while connected to Wi-Fi. Then activate it after landing in Vietnam.
For iOS: Settings → Cellular → Current Period Roaming
For Android: Settings → Connections → Data Usage
Go to your phone’s settings → mobile network or SIM settings → select the eSIM and choose "Remove" or "Delete plan". Confirm the removal to delete the eSIM.
