Lucky Bolt

Ok, what the hay is going on? I was in the middle of chatting with a friend over text and all of a sudden he's not answering me, but it says my texts were sent successfully and that he viewed them.  And not just him, I've also been trying to get a hold of @Cyclone over text and can't, having the same issues. 

I mean, I have internet, restarted my phone, and made sure everything is working but no luck. Either everyone I'm trying to get a hold of over text is playing some cruel joke on me, or, there is genuinely something wrong with my phone.  I'm in panic mode
