Q: My 5C iPhone does not have Wi-Fi Calling under Settings>Phone with IOS 9.3.3
Apple states that Wi-Fi Calling is optional with the 5C and IOS 9 and later. Mine does not show this option under Settings>Phone. Have IOS 9.3.3. Why could this be?

Of course the carrier has the ability to affect select carrier-controlled settings via over the air updates and such. They and the settings they've provisioned on your account will, for example, determine if the "Personal HotSpot" setting shows up or not. Similarly for wifi calling. They can choose which settings are present and enabled under the "Phone" section as determined by what they enable on your account.
If AT&T decides not to support a carrier-controlled feature on particular hardware, or on someone's specific account, they can indeed control what features settings appear or are useable on your device.
Apple merely makes the hardware and iOS compatible with a feature, but carriers control which features they choose to support on their network, and for which devices and accounts they wish to provide those features to.
