In many markets, the ability to choose a telephone number is important to end-users. Whether it's a number with a cultural or personal significance or simply an easy to remember number, being able to offer the choice to customers will provide the operator with a competitive advantage and also an opportunity to increase revenues, as charges can be applied to these numbers.

Whilst many operators offer number choice to postpaid customers, most can only offer it to prepaid customers through very limited channels - often only via a flagship store at the operator's headquarters.

Dynamic SIM Allocation™ provides an opportunity to offer number choice to prepaid subscribers at the time of first use, via the handset. This hugely increases the number of potential customers who can be attracted with this differentiated service, and also increases the revenue potential from charging for vanity or golden numbers. The handset dialogue can be tailored to support varying degrees of number selection and a tiered charging structure.

The time of first use is also the ideal opportunity to offer additional, value-added services to a new subscriber. The same handset-based dialogue that supports number choice can also be used to offer other services, further increasing the incremental revenue opportunity.
