Hello- I am unable to authetinuate on my cell phone because i am not recieveing SMS texts

See if the following article can help: If you can't send or receive messages on your iPhone, iPad, or iPod touch - Apple Support

Then the last step in that article refers you to contact Apple Support directly. I suggest that should be your next step. You can get that started by selecting the "Get Support" link in the upper right-hand side of this forum's web page.
