As of yesterday around 11:00, I noticed a text i sent was still "sending" I can't send any text, I can receive text, I can use all my other app and the internet just can't send text. I've shut my phone down, restarted, shut it down, removed battery, keep it off all night long, started it up again still can not text. I did call customer service last night and the lady that helped me could not help after 25 minutes, most of the time on hold, I gave up with her. Any suggestions?
