Hello and welcome to Apple Support Communities, Coachrsh.
If I understand your post correctly, when you are not connected to Wi-Fi you're unable to search for Gifs in Messages. Gifs are a fun way to add to your messages. I'd like to help.
Let's make sure cellular data is enabled. This guide will show you how:
Check the cellular data usage on your iPhone and iPad
Let us know if that resolves this issue for you.
Thanks for using the Apple Support Communities. Take care.
