IPhone 4 will not send or receive group text messages?

My iPhone 4 recently decided it did not want to send or receive group text. I have reset the phone, I have MMS turned on, group messaging turned on, and it is updated to the most recent version of iOS.

The weird part is that my iPad and iPod where both receiving group texts through iMessage. If I turn iMessage on on my iPhone though, it sends text from my email even it I tell it to only send and receive from my phone number.

Has anyone else had this problem and do you know how to fix it?

My sister had this problem a few days ago when my mom cut service to her phone. Maybe you don't have service…

Just talk to the individual person who cares

After trying everything suggested on the internet I took it to Verizon. They checked out 'network settings' and found 2 'blocks' that were the problem. Works fine now!

  • Why does my iPhone receive messages late when I'm in a group text? I have the iPhone 4s with 16g (I have less than a gig left of space) and am on T-Mobile. Every single time I'm added to a new group text, my phone delays all messages sent to me. Regardless of whether it's another iPhone or if they're on the same carrier as me, none of my messages get to me until an hour or so later. Is it because I'm low on space? Or is it T-Mobile (probably the worst carrier I've ever had by the way)? Or is it the iPhone software?
  • Why does my iphone not receive group messages unless 4g is on? When I'm at home and I'm using Wi-Fi I always turn off cellular data because I don't want to accidentally be using up my data, but whenever it is off I never receive group messages until I turn it back on? Why does it so this and can I make it so I can still receive group messages when only using Wi-Fi?
  • My photos are not sending in group messages, but are sending in individual messages? I'm with Straight Talk Wireless. At first my pictures were sending in the group message but now they are not. I don't know what's wrong, all my settings are what they are suppose to be, and I'm currently on an iPhone 5s IOS 8.4.
  • My New iPhone 4 won't send or receive text messages? I have checked the service centre number which is correct, I have updated the ios software thing (I'm not too clever with Apple products but yes it's been updated).It says iMessage is waiting for activation but it has said this for ages now. I have tried absolutely everything with still nothing. I can make calls, use the internet, I can do everything else! I just can't send or receive text messages… Will someone please help me?
