Cellular on Apple watch in Jordan

Since there is no Cellular support for Apple Watch in Jordan, unless you bought the watch in a country where there is cellular support the cellular feature would not exist on your Apple watch anywhere nor would it be available in the Watch App

The fact there is no option for it in the Watch App means you have a non-cellular watch.

When the mobile carriers there support it. It's not up to Apple, its up to the carriers.

Contact your service provider and tell them you want Apple Watch support.
