What are 'Carrier Settings'?

Question

I have been getting a daily message on my iPhone saying "Carrier settings update.  Do you want to update now?"  I have been tapping the "Not now" button because it appears suspicious and I can't find anything in "Settings" to indicate there is some kind of update pending.  Does anyone know anything about this?

BDM3951,

I know message like this can seem odd to receive. I have an iPhone as well and I’ve received this message too. Allow us to help. Carrier settings updates are small files that can include updates from Apple and your carrier to carrier-related settings, such as network, calling, cellular data, messaging, personal hotspot, and voicemail settings. I hope this information help.
