 A study conducted by Roy Morgan Research in February 2006 indicated that 92% of Australians were aware of alphanumeric dialling.In the age of advanced mobile devices, there is some disadvantage in using phonewords.Devices with physical keyboards such as BlackBerry and some other smartphones do not have the apportioned letters on the keys used for dialing, so one is unable to do alphabetic dialing without some other cross-reference to the actual phone number.
