If you frequently use a mobile phone for business calls and text messages, you know that the fees from your carrier can add up quickly. But with suitable apps and programs, you can add an office line that lets you use Wi-Fi to make voice calls and send texts from your mobile device or desktop at no extra charge, using the Internet service you already pay for. Having a second phone line for business also can help you separate your work from your personal life.
A VoIP (Voice over Internet Protocol) line can be an inexpensive way to add a second phone line for business use. VoIP enables you to make voice calls over an Internet connection. Using VoIP, you can even transform a Wi-Fi-only device such as an iPod Touch into a phone, make cheap or free phone calls from your computer, or conserve your mobile minutes by making calls over the 3G or 4G data network or Wi-Fi connection.
