So I upgraded today from Textfree Lite to Textfree Unlimited because now this app is free. Since the lite version had ads, I am used to them and won't being paying $6 a year to remove them with this upgrade. They also give you a real phone number for the app. I am a bit confused as to what the advantage is of having this number. I didn't have a number with the lite version. Someone please educate me.
