T-Mobile offers a cellular “Watch plan” that shares your iPhone number and “Standalone watch plan” with its own number. Which would have more advantages? Can the standalone number be shared in my iCloud account as another device the same as my iPad and Mac in order to receive calls and messages?
iPhone 16 Pro, iOS 26
you want the share your iPhone number plan.
and it is possible to get the cost down to $5 a month if you let T-Mobile automatically withdraw money.
The standalone number is for family sharing associated with a dependent child where the parent’s iPhone controls the child’s Apple Watch. Also the functionality of the Apple Watch is severely limited. And it costs more per month than sharing your iPhone number plan.

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.
