I have a corporate phone and a personal apple watch. I purchased the watch with its own cellular plan through ATT. The watch synced with the phone just fine, but when I try to set up cellular, I get a message saying my device (the phone) is suspended. Can I not set up the cellular line for the watch directly from the watch without needing the phone?

Most corporate iPhone plans will not allow you to add the Apple Watch to the plan.
If your iPhone supports Dual SIMs (physical SIM and eSIM), you can get a separate eSIM based plan from a carrier that supports both iPhone eSIM and supports the Apple Watch, and have your Apple Watch paired to the eSIM plan on your iPhone.
