I enabled "pay as you roam" through Starhub app and when I checking out "Manage VASes", it will show "Pay As you roam" as already selected.
But still, I don't have any network connectivity. Please help me on this ASAP.
If you're still experiencing issues as of now after switching off and on the phone, or if you have tried your SIM card on another phone, please ensure that your data roaming is switched on, on your device by going to Settings > Mobile Data > Turn on Mobile Data and Data Roaming.
Hope this helps.
