Frequently Asked Questions — Vietnam eSIM
Is my phone compatible with an eSIM?
Most modern smartphones support eSIM, including iPhone XS and later, Google Pixel 3 and later, and many Samsung Galaxy S and Z series devices. Check your device settings under Mobile Data or Connections to confirm eSIM support.
When does my Vietnam eSIM plan start?
Your plan activates when your device first connects to a network in Vietnam — not at the time of purchase. You can install the eSIM before your trip without wasting any days.
What is the difference between Lite, Essential, and Plus?
Unlimited Lite offers standard speed — great for everyday browsing and messaging. Unlimited Essential delivers 4G LTE speeds for streaming and video calls. Unlimited Plus provides 4G LTE Max Priority, meaning your connection is prioritised even in busy areas like airports and tourist hotspots.
Can I use my eSIM for calls and SMS?
AloOui Vietnam eSIM plans are data-only. For calls and SMS, you can use internet-based apps like WhatsApp, FaceTime, or Messenger, or keep your home SIM active for traditional calls.
How do I install my Vietnam eSIM?
After purchase, you will receive a QR code by email. Go to your phone's Settings → Mobile Data (or Cellular) → Add eSIM → Scan QR Code. The process takes under 2 minutes.
Does the eSIM work in rural Vietnam and on Ha Long Bay cruises?
Coverage is excellent in major cities and tourist areas. In very remote regions or on open water, signal may be limited — this is normal for any mobile network in Vietnam.
