Apple Watch SE can't make or receive calls

So my son recently just bought the Apple Watch SE (1st gen) new from Walmart. The selling describes full 5g capability with calling and texting. He does not have his own phone, so I paired it with my iPhone 7 plus (yes its old) using family setup. Yesterday we went and got a T-Mobile Watch plan for $10 a month yet it can't call (only text and use other cellular capabilities). When Me or my wife try to call him, we get the "The person you have dialed is not able to receive call right now" error message. Even weirder, he get some of my texts and my calls too. When he dials me, it will not show on my i-Phone. We tried looking all over the web and even at the Apple Store to find a solution, but we just can't find one. I'm hoping someone from this community can help me solve this.


For reference I am running iOS 15.7.8 and my son is running WatchOS 8.8.1.


Thanks!

Hi tofu_is_soft_lol,


Thanks for posting here in Apple Support Communities. You may want to verify in Settings that the Apple Watch currently has an active cellular plan as to may help to address the issue you're facing. See: Set up Apple Watch for a family member - Apple Support


Set up cellular and Wi-Fi
If your iPhone cellular provider supports Family Setup, you can add the watch to your plan during this step.
If your carrier doesn't support Family Setup, or you'd like to use a different carrier, select Not Now.* You can choose an alternative carrier from this list of supported carriers and contact them directly to set up your cellular plan. 
Next, choose whether to share your current Wi-Fi network with the Apple Watch.

Kind regards.
