For many of us, our smartphones have become our primary communication tool, but there are moments when you'd rather not give out your personal cell number. Whether you are selling something or doing business with people in another state or country, you'd probably prefer to keep your personal number private. For those situations that could require a second phone number, take a look at an app called TextMe Up. TextMe Up allows you to create special phone numbers, including international numbers, for specific reasons which allows you to keep your personal number private. You can also text anyone in the world through these secondary numbers, as long as you are willing to put up with ads in the messaging app. For anyone that wants separate phone numbers for different parts of your private and public life, TextMe Up can be of help. The app is available for both iPhone and Android users and your first number is free at http://TextMeUp.com
