You may want to check Settings > Apps > Messages, then make sure iMessage is turned on.
If you are sending to non-Apple (eg: Android) users, text messages in the Messages app must use cellular.
Apple to Apple devices use wi-fi for iMessages if the signal is strong enough, else they use cellular as well.

Wi-fi Assist is generally on by default,(ie switches between cellular and wi-fi) yet can be turned off, or back on, as you wish:
