Hi sorry for being so noobish but what apps do that? All ive managed to do was root it

Hi there, Im very new to the forums actually I registered just to ask this question: My brand new Star N9770 I just got the SIM card for it (from Straight Talk) and I followed the directions exactly but it wont let me do anything at all. But sometimes it comes up as roaming and lets me put terrible quality phone calls through from half a second or send one txt but get no reply. I need help what ever you know please tell me!!!!
