Messages Not Sent
Sometimes it happens that you are chatting with someone and then the screen shows you "Message not sent, touch to try again". You try again and again to send the same message but it shows the same awkward alert.
The first thing you should do is make sure you are connected to a WiFi network or your mobile network is working properly. Then, click on the message that was not sent and select the forwarding option. This should suffice, but if you still have the same issue, try restarting your phone or trying to download another message service.
