Dependable mobile number validation

SMS messaging is an affordable mechanism to communicate with customers, however people change their numbers, travel out of their home network and even change service providers while keeping their original mobile numbers. Keeping track of this can be challenging to a business, and can lead to lost SMS costs and a reduced return on investment (ROI).

Identifying a need for number validation

SMS campaigns may be created to cater for a specific time period, or to reach a target market in a specific region. It is possible that a customer is off network, or is in a meeting. Knowing beforehand what numbers are available for sending can substantially reduce the costs of an SMS marketing campaign.
