Usage steps

1. After receiving the card, remove and insert it according to the size of the SIM card slot.
2. Reboot your device and enable "Mobile Data" and "Data Roaming".
3. APN is usually set automatically; if not connected, please manually add an APN, save it, and then restart.

A friendly reminder: It is recommended to insert and activate the SIM card upon arrival at the destination to avoid premature timing; whether hotspot/network sharing is supported depends on the plan.

Daily traffic updates are made after midnight (calendar day, not 24-hour).

Friendly reminder:

• For Vietnamese physical SIM cards or eSIMs, it has been found that once in Vietnam, mobile data and data roaming can be turned on to access the internet, but they will automatically connect to Mobifone Telecom (which has a relatively poor network). Please try to manually select Viettel or Vinaphone Telecom (which will have a better network).
• On an iPhone, you can go to network selection, turn off automatic mode, let it search for networks, and manually select Viettel or Vinaphone.
• On Android phones, you can go to the telecom operator's page, turn off automatic mode, let it search for networks, and manually select Viettel or Vinaphone.
