Setting the iPhone for TPG SIMBA outgoing and incoming calls in Singapore

So our TPG / SIMBA SIM card cannot make outgoing calls and receive incoming calls in Singapore. 

Here's what we did to make it work on our iPhone SE 2020...

  • iPhone – Most of the iPhone from iPhone 7 and above. The default iPhone setting stays VOLTE OFF and need to be enabled manually via VoLTE toggle in Settings > Mobile Data > Mobile Data Options > VoLTE is set to ON

Other Settings we did on the iPhone. 
  • Tap Settings > General > Software Update to install the latest iOS
  • Check and ensure your device is connected to TPG network and configured with TPG APN setting
  • Proceed to Settings > Mobile Data > Mobile Data Options > Voice & Data
  • Select LTE or 4G and enable VoLTE
  • Go ahead and make a call!

It's working now!
