If you need more than what a plan offers then grab an add-on with your plan to make it just right.
You can even mix and match 4-Weekly and Weekly Plans and Add-Ons except where there is no additional benefit (such as buying more minutes on an unlimited minute plan). And remember, you're not forever stuck with what you choose. So you can come back next time and choose add-ons according to your usage habits.
