Verizon iPhone 4 not sending texts?

I have an iPhone 4 though Verizon. Last week it was brought to my attention that my friend had texted me twice, however i never got them. So this got me thinking maybe i also hadnt been able to send messages.

I looked online to check to see if a message i had sent that didn't get a response had been sent, and it did NOT show up on my verizon account. But my phone said it sent.

What's going on? Is there anything i can do?

Shut off and restart the device… It gets a new network address for receiving and sending texts… So I'm told. In which case, it must be your friends network. Iphone works amazing.

  • Why isn't my iPhone 5 not receiving or sending texts to andriod phones? I just recently got an iPhone 5 (regular. Not 5s or 5c). I haven't updated to iOS7 yet but ever since I've gotten this phone it hasn't received or sent text messages to an android phone. I haven't tried calling yet so I'm not sure about that yet.
  • Why is my iPhone sending picture messages as texts? I have had an iPhone through Verizon since last June, and recently it has started sending all of my picture messages as texts instead of iMessages. I have a texting plan, but it's still frustrating that I can iMessage my friends any other time, but when I send a picture it becomes a text. I have checked all of my settings, and nothing has been changed. Does anyone know what could be causing this?
  • Why is my iphone 4s sending texts to everyone except one person in specific? I have an iPhone 4S, I've been texting a few people today but there's this one person in specific that my phone doesn't let my message go through to them? It just randomly happened in the middle of one of our conversations when I tried to reply but all it says is "message send failure." I didn't want to, but I deleted our whole message history and still nothing.
  • Texts messages not sending after iPhone update? I updated my phone two days ago. Last night my phone stopped sending & receiving texts. I was able to text one person, but everyone else I couldn't. I wasn't even getting a notification that my texts didn't send. What should I do? (I tried turning off iMessage & shutting off my phone, then turning it back on, but that didn't help).
