Pairing Apple Watch LTE with new phone number, independent of paired iPhone

We want to buy an Apple Watch with LTE (e-sim) for our child. The child does not have an iPhone, so we need to perform the first pairing on our phone, which Apple allows. My question is... is it possible to enter a new phone number via a paired phone, which will then work independently of the paired iPhone. The point is that the iPhone does not ring when a call comes in.

Some limitations: Cannot receive SMS/MMS messages, as that depends on a fully paired iPhone. Messaging is pretty much limited to Apple’s Messages, unless the messaging service provides an Apple Watch app. Alarms, alerts, notifications on the iPhone are not sent to the Apple Watch. Apple Pay via a credit card is not available. Also not available: Medications, respiratory rate, irregular heart rhythm notifications, ECG, AFib History, Cycle Tracking, Sleep, Wrist Temperature, Blood Oxygen, Walking Steadiness, Audiobooks, Camera Remote, News, Shortcuts, and the double tap gesture.
