I can't make calls and my galaxy watch

For watch to work properly you need to login to your Tmobile account and locate your watch.  You should see a message to pair with Tmobile digits.  Pair your watch with the phone of your choice.  Once paired it will take about 5 minutes to fully pair.  To test disconnect watch from Bluetooth and WiFi.  Watch should then be able to make calls without being connected to Bluetooth and paired to phone.  Also when watch is not paired to Tmobile digits it will give a busy signal when you try to make a call.  Galaxy watch 5 44mm and Galaxy Fold 3 were my devices.  Took 3 hours to figure this out and spoke to like 5 different Tmobile reps before I was told to look at my Tmobile account.  Don't use the Tmobile App to perform those task.
