can i use a apple watch paired with my iphone thru verixon total

Here is an answer from Verizon --> Apple Watch - Set Up Cellular Service

During the pairing and setup process, tap. Set Up Cellular · Enter your username to sign in to the My Verizon app. · Enter your password. · Tap · If prompted, tap.

You need to mention what is the difficulty that you are facing either for pairing or after pairing.
