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. This can be overcome by phonewords also being accompanied by the actual numeric phone number, allowing users of such smartphones to dial using the numeric phone number.
