I am having a lot of trouble sending text messages. I get them fine but cannot reply to them. It just sits there pretending to send randomly. If I have my mobile data off it won't ever send texts even using the stock Messages app with the default group text mode disabled. Anyone know why I cannot send text messages without my mobile data enabled?? I feel this might be the root of my texting issues. Note these are plain LOL and simple texts with no attachments. Even with full bars of 4g no luck half the time sending with mobile data enabled...
