My iPhone won't receive texts?

I recently got given a iPhone 4S by cousin as she got an upgrade. I'm with Vodafone. I can receive texts when I'm in my own Wi-Fi area, but whenever I'm not at home I don't receieve any of my texts till I reach home. Receiving calls is fine. Is there anyway I can receieve my texts?

Make sure you are getting them as texts not Imessages

Go into settings and then Messages. If it is not needed, turn off iMessage. That will restrict all the texts you send to your SMS allowance with Vodafone instead of using Apple's instant messaging system.

Hope this helped!

  • Why won't my new iPhone 6 (AT&T) send or receive texts/calls? I activated it two hours ago and backed it up with the data and phone number from my old iPhone 4. Both phones now read AT&T and show cellular signal and data in the top left hand corner. But when you text or call my phone number, the iPhone 4 receives it. Why won't my new phone receive it?
  • Why won't my iphone send or receive texts? I have just bought an iPhone off my friend. I also have free texts. It sometimes says that I have signal and other times says that I don't have any. But whenever I try and send a text they won't send. I also don't receive any messages either. Does anybody know why this is happening?
  • My new iPhone 5 won't receive some texts? I got it yesterday and I use bell. I'll only not get some of them but its still annoying and then I'll end up getting them like an hour later after they were sent! Why is this happening and how can I fix it?
  • My iPhone won't receive texts messages? Unless I turn my phone on and off, sometimes I don't get calls and it won't even show up later saying I have even received them. It doesn't happen all the time mainly 5-6 times a week, but it does cause problems because I don't know if I have a text until I turn it off and on then it could be hours late. Just wondering if I can fix this or if I need to contact my network for help?
