For Multiple Numbers, It Pays to Keep It SIMple

In order to achieve mobility, subscribers have often been forced into a model of multiplicity: a smartphone for personal use, another for business, a fixed line at home and, increasingly, a tablet with an assigned phone number as well. There have been recent solutions to consolidate the number of devices we have, from Bring Your Own Device (BYOD) initiatives that look to combine personal and business devices, to a growing number of homeowners who have jettisoned their landlines. Yet all of these solutions have their drawbacks. Personal devices and corporate policies don’t always mix, home numbers have a long-standing history that we don’t want to lose, and so subscribers end up paying the price by maintaining more devices than they really require.One Dialogic business partner, PCI-Suntek Technology, has come up with a unique solution to the problem: a Multiple Subscriber Number (MSN) service that operates from a single subscriber identity management (SIM) card. Their MSN solution enables subscribers to host multiple phone numbers on a single SIM card/mobile device, while enjoying “multidevice” functionality such as incoming/outgoing calls on different numbers, customized white/blacklists for each number, unique outgoing messages, etc.

PCI-Suntek’s MSN solution disrupts the limiting one device/one number approach to personal communications and allows subscribers to have more flexibility in how they communicate without the complexity and cost of owning multiple devices. There are several scenarios where this solution can pay immediate dividends for subscribers including:

  • The Business Traveller: Imagine a businessperson whose work often takes them between the U.S. and the U.K. Having a regional number for each country assigned to a single device would allow them to make “local” calls in either country without switching their phones.
  • The Part-Time Seller: There are many cases, such as a homeowner selling their home, when an individual would prefer not to give out their personal number. The MSN solution allows subscribers to add a temporary number to their phone for a period of time, while keeping their personal number private.
  • The Cord Cutter: As subscribers continue to consolidate their communications in favor of wireless, one of the primary stumbling blocks to cutting the cord on their landline service is the loss of an established home number. The ability to migrate that number to their mobile device while retaining their existing mobile number is an attractive option for subscribers who want to save money without losing touch with the people who use that number to contact them.

The MSN solution supports both voice and SMS (i.e., text) services. Subscribers can send and receive calls and texts from any number that is linked to their device through the MSN platform, and easily toggle between different numbers based on the situation. The MSN service also reduces complexity by consolidating account management and billing charges for multiple numbers under a single account. Given the fact that new smartphones can cost upwards of $1,000, being able to get more value from your mobile device is SIMply a smart way to manage your communications.
