Singapore eSIM not connecting: the checks, in order

The checks

First comes the eSIM line: it has to be switched on. Second, it is chosen for mobile data. Third, give airplane mode ten seconds on and off, or restart the handset. Fourth, with data still stuck, data roaming goes on for the eSIM line.

Pick the network by hand

The eSIM line’s settings hold a switch for automatic network selection: turn it off, then work down the list of networks one at a time. Wait a minute on each one.

When the data runs out

Data that worked, then quit? Look at your order page: the plan’s days or data are used up, so mobile data may slow or stop for the rest of the plan.

Write to support

If nothing works, write to the store’s support while you are still in Singapore, with your order page link, your phone model and screenshots of the mobile data settings. The store is the one dealing with orders, QR codes and refunds; its support replies in English and Vietnamese. An eSIM beyond any fix is refunded in full: see refunds.
