Iphone 4S text messaging acting up?

This is already the third time that it's happened this year. I get my text messages late. If someone sends me a message at around 3pm, I won't get it til at least ten minutes later, sometimes even a hour but when I do receive it, it says the message was sent at 3. The first time, it only lasted about a week or so. The second, it lasted about a month.iMessage is not on. There are two other iPhone users in my family but they have not had this problem before. Can someone please help?

Sounds like you need to reset your network settings.
-Settings, General, Reset, Reset Network Settings.
-This will power off your phone and turn it back on and reconnect to every network, including your carrier and Wi-Fi. However, you'll have to reconnect to your Wi-Fi yourself, with the password again.

  • Why can't my iPhone send or receive pictures in text messaging? My dad bought me the iPhone 4S unlocked. I got the prepaid service at tmobile which was 50$ unlimited talk text and web. I can't send pictures during text messages and I can't receive them. If someone sends me a picture I don't get it, it's just blank. The little camera icon next to the text area to type is light grey indicating I can't press on it. I can only send or receive during iMessage. Please tell me why this is happening.

  • Text messaging with iPhone So, I was writing this HUGE text message to a friend in help and before I could even press send, my phone shut down because it ran out of batteries. Will my message still be there after my phone opens even if I didn't send it! Is there a way to get it back! It took me a lot of time to write it and it won't be as good the second time I do.
  • Problem with text messaging on iPhone? My mother has an iPhone, and today I got my first. However, whenever I send a receive texts, they go to her iPhone as well. This did not happen at all with my last phone, which was an android. Why is this happening? It's irritating, and I need a fix as soon as possible.
