Do I need Norton Mobile if I have Life Lock?

I have Norton Mobile on my smart phone and Life lock on my PC's and mobile. My question is do I still need to have Norton Mobile installed on my Phone Now that I have Life Lock.
It seams a bit Belt and Braces, also maybe an unneeded expense.

Hope someone can help with this simple question that I have not been able to find an answer to.

 

We need to define a couple of things here. 

Norton and LifeLock were different companies that were merged some time ago now into Norton/LifeLock. Norton provides the AV products,and LifeLock provides credit monitoring services. So the two are separate functions/features. 

When you say you have LifeLock on your PC, are you referring to the Norton/LifeLock 360 product? If so, your Norton Mobile product(s) should have already been updated to the new Norton/LifeLock mobile versions. No need to install any separate app.
