Carrier benefits.
VoiceSMS is a premium messaging service. Sold as an enhancement to SMS text messaging, VoiceSMS is a popular "workgroup" communication tool. For businesses, VoiceSMS is perfect for moving messages among busy managers, sales reps and other professionals. For families, VoiceSMS is a great way to stay in touch.
VoiceSMS doesn't compete with text messaging. In studies by Core Mobility and carrier partners, VoiceSMS was found to augment, not replace, text messaging usage. Voice and text are significantly different media and are used for different purposes.
VoiceSMS is a great way to promote mobile data services and differentiate service offerings. VoiceSMS requires mobile data services, and may motivate some users to upgrade to a mobile data plan.
Core Mobility offers a variety of billing options for VoiceSMS subscribers, including prepayment and post-payment, and the service is available as either a licensed or a hosted (ASP) solution.
