👉 You can check compatibility here: Compatible devices
Can I use my NoveSIM Vietnam plan for hotspot/tethering?
Yes! NoveSIM supports hotspot/tethering for Vietnam. You can share your data with laptops, tablets, or other devices without any restrictions.
When does my eSIM validity start?
Your validity period starts only when the eSIM connects to a local network in Vietnam. You can purchase and install it earlier - it won't activate until you land and the phone detects the network.
Does the eSIM support calls and SMS?
NoveSIM Vietnam plans are data-only. You can still make calls through apps like WhatsApp, Viber, FaceTime, Messenger, and others.
Do I need to change APN settings?
Usually no — the APN configures automatically. If needed, the APN is typically:
APN: data.esim
(no username, no password)
Does the eSIM work immediately after installation?
Yes. After scanning the QR and installing the eSIM, it becomes available on your phone. It will auto-activate once you arrive in Vietnam and turn on mobile data & data roaming.
Can I use the eSIM in multiple countries?
If the plan you selected is regional or global, it will work in all included countries. If it is Vietnam-only, it will work exclusively there.
What if my eSIM doesn’t work when I arrive?
Try the following quick checks:
Turn on Data Roaming
Select Automatic Network Selection
Restart your phone
APN should be set to: data.esim
