Help I want to reset my Galaxy S5, but how do I save my conversations of Text Messages?

Basically, I have a bunch of text messages I want to keep on my phone, but is there a way I can save them and my contacts while doing a full system reset?

Helium Backup from the Play Store will help with that.
