I received my contract phone this morning and I can't send text messages. I can ring people fine though? I went to the T-Mobile store and they told me to ring 150 which is customer services. I rang them, but they told me to go to the store which I was pretty hacked off about. I have unlimited texts and 600 minutes, just in case the tarriff matters. I've tried pulling the battery out and everything, nothing seems to be working 
please help me!! Thanks.
