My iPhone 5 with AT&T won't receive group messages?

Last Sunday I switched to AT&T from Verizon with my iPhone 5. Prior to this I can receive and send group messages without fail. But as of yesterday I can send messages into my group chat but I can't receive any at all. I can still text people outside the group chat but I feel like I'm missing out lol. Does anyone else have this problem?

Get new phone i guess

Make sure you have group messages turned on in your settings

  • 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?
  • When I receive text messages with emojis from an iPhone, why do the messages only appear partially? My phone is a "Verizon Samsung Intensity II" slide phone. (Also it's blue but that doesn't matter.) Also, if I'm included in an iPhone group chat (spoiled rich friends, but not snobby…), I get each posted message as a separate message, so I'll end up randomly with 67 unread messages clogging up my inbox.
  • 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.
