If you have a mobile phone, ditch your land line. If you feel you absolutely have to have a land line, sign up for a VoIP service that places calls over your Internet connection for much less than a traditional phone service.
Ooma is a service that gets high marks for customer satisfaction and voice quality. It requires you to buy a $139 Ooma device, but then you get almost free phone service for life. You have to pay the taxes each month, which, depending on your state, run about $3 or $4.
You could also buy a magicJack PLUS™ VoIP Phone Adapter for $80, then your cost is just $30 a year.
You can also place video calls for free using Facebook Video Calling or a Google+ Hangout. Heywire and Textfree are free apps that allow you to send texts and pictures for free. Use Skype to make calls from your computer to a landline for about $3 a month. Also use Skype to make unlimited calls to landlines or use Skype to make cheap calls internationally.
