25 Android and iPhone Apps to Add a Second Phone Number for Business Only Calls

A smartphone is just as much a business communication device as it is a personal one. But using a single number for both on your phone is unprofessional and unnecessarily problematic. But smartphone technology and the many apps available in the marketplace allow you to easily get a second phone number avoiding these problems entirely.

If your phone can accept a second SIM card, you can get another number from your service provider. However, if you don’t want to use this option or can’t because you don’t have a secondary SIM slot, you can use an app to get a second number on your phone.
