iPhone 5s and carrier update

[Kimwerner]

Keep getting a pop up saying that a carrier update is available.  Never seen this in all the years I've had my phone and want to know if it's legit and if it's required for an iPhone 5s?

Kimwerner,

Allow me to put your mind at ease. That is an update we are sending to iPhones. I encourage you to go ahead and process it.
