absolutely everything else it is? designed to do, except receive text messages (eg. I can go on the internet, make phonecalls, receive phone calls). I can even send text messages, I just can't receive them. I have also tried restarting the phone, taking out the battery and sim card and putting them back in, turning airplane mode on and off, and even letting it die without charging and letting it restart by being plugged into its charger, and still nothing. Any ideas?
