If you have a mobile plan with Singtel, the default ring time for incoming calls is 15 seconds. You can adjust that yourself up to 30 seconds, by doing this:
- Go to your mobile phone’s dialer pad
- EnterÂ **61*1389**30# and then press the Call button. (Change ’30’ to whatever number of seconds you want the rings to last, up to 30.)
- No call will be made but you should see a text confirmation.
Some bloggers indicate that one can go up to 60 seconds if one disables voicemail. (If you are a business, please don’t disable your voicemail. Providing your hours of operation in your voice greeting is very helpful.)
