Whenever I send a longer text I get a message saying it has been sent as an out of plan MMS. I assume it's maybe because those longer texts also have emoji? I know i can prevent the charges by not using emoji but I've never had to think about that before ie it's never been an issue and always been included in plans with other networks. Is there a way of blocking mms or setting it up so it converts to an sms and removes the emoji to just special characters? It's a pain having to remember not to use them when it's habitual!
