Welcome to Android Central! Sorry, but you need to be clearer with your question. Which Android phone do you have, and which carrier? In order for your phone number to work, you have to make sure the phone has a valid and activated SIM card (if it's a GSM phone), or if it's a CDMA phone, you have to make sure the carrier has activated the phone itself.

Or are you talking about logging into your Google account?
