My line used to be able to ring for 1min...
but now after changing sim card... it defaults to ring for 15sec... i extended it through **61*1389*11*30#
only able to extend to 30sec... which is the max according to singtel hotline...
anyone knows how to extend to 1min?
entering 60 instead of 30 at the end... does not work
