IP address stands for Internet Protocol Address, it's practically an address given to an internet user to identify that specific one.
If you have a cell phone with internet such as iPhone, then from whatever Wi-Fi you're leeching off of, that will be its IP address temporarily till you dislocate and move on to another. Otherwise no, if your cell phone doesn't have any internet, it won't have an IP address. Because... there's no reason why it should have one.
