Malaysia eSIM not connecting: the checks, in order

  • Line on
  • Mobile data on the eSIM
  • Pick the network by hand

The short answer

Check four things in order: the eSIM line is on, it is chosen for mobile data, airplane mode has been switched off and on, and data roaming is on for the line if it does not connect. Then pick a network by hand. If it still fails, write to the store's support while you are in Malaysia.

The checks

Start with the eSIM line itself: it has to be on. Second, it is chosen for mobile data. Third, give airplane mode ten seconds on, then off, or restart the phone. Fourth, if data still will not start, turn on data roaming for the eSIM line.

Pick the network by hand

Inside that line’s settings, switch off automatic selection, then work through the networks in the list, one at a time. Wait a minute on each one.

When the data runs out

When data worked and then quit, open your order page: after the plan’s days or data run out, the line may slow or stop until the plan is over.

Write to support

If nothing works, write to the store’s support while you are still in Malaysia, with your order page link, your phone model and screenshots of the mobile data settings. Orders, QR codes and refunds are handled by the store, and its support answers in English and Vietnamese. Where no fix makes the eSIM work, the refund is full: see refunds.

Still stuck?

Orders, QR codes and refunds are handled by VietSIM support. Write with the link to your order page and your phone model.
