I go to messages, then compose a message and choose to send it to someones email address. But they never receive the message. When I go to the message, by it is a box with 3 horizontal lines on, and at the top right of this is a clock. Please help. Edit: I turned off the wifi and tried re-sending them. This time it sent the MMS messages to the email addresses. Still no luck sending MMS messages over wifi though.
