Yes, some state telemarketing laws prohibit you from making calls during a state of emergency. However, it is less clear when it comes to texting. Other than the 15 states that treat text messages separately, it is not clear whether a regulator would say texting is a call. A lot of state-level statutes about states of emergency are worded in such a way that calls are explicitly prohibited while texts are not. But as a practical matter, it is best not to call or text during states of emergency.
