I'm 15 years old. (Please don't say "Oh you're just 15!"). Honor roll, straight A student. I currently have a Samsung Freeform from MetroPCS, and I'm okay with it BUT for some reason, recently I haven't been receiving calls or texts, and I can't send messages. At first I thought my phone was disconnected, so I went to Metro and they said it was just the phone. Now I have to upgrade, and I REALLY want the Blackberry but my mom doesn't want me to get it. What should I do to convince her?
