Ok, I have searched hundreds of threads on the issue I am having with no luck. I upgraded my phone from an iPhone 4 to a Galaxy s4 yesterday. Well, I am not receiving texts from certain iPhone users. I've done everything in the other threads I've read such as change my apple password. I was going to unregister my phone from Apple but it turns out I never registered it anyway. I know it has something to do with imessaging. And I'm sure if I turned off imessaging on my phone it woukd fix the problem. The only thing is, my phone will not turn on. It is completely fried. Please someone help me!! Thanks in advance!!
