Can Apple give an option to check cellular data usage for every bill cycle?

As an addendum to bmike's answer, this may be entirely provider-dependant.

On O2 UK, I have no option to view my usage per bill cycle, only since last manual reset. My provider has an app to view usage [& many other provider options].

The Euro-equivalent to 'Cellular', Mobile Data show the overall usage since last reset, plus a long list of usage per app below.
It is not tied to the provider's billing cycle at all.

I do, btw, have my provider's profile correctly installed; this is not a configuration error. The blue 'Network Provider Services' links through to their home page, for those who don't have their app.

Not all carriers feed the data, but Apple provides two methods to interact with traditional cellular services:

• sms short codes
• cellular item in the settings app via structured data exchange

Not all carriers send the data to the device, so not all phones will show what the iOS is capable of showing.

I prefer seeing the data and dates - so tap settings, tap cellular, tap usage.

You can see much of the data one screen prior to the detailed settings that show precisely when the carrier reports a billing cycle ends. Of course, Apple just is the conduit - you should reach out to your carrier to understand if they take advantage of Apple’s standard interface or require you to use a custom app or sending SMS short codes or get your usage data in some other non-standard manner.
