So i just got my phone on christmas, and I was texting people during the day and it seemed that I wasnt getting their Text messages right away..so yesterday i was with my girlfriend and texted her sitting right next to me to see what would happen, she got mine almost instantly but when I had her send something back it took 5 minutes before I got it...whats wrong with it? is it my phone? is it the network? can i do anything to fix it?
