T-Mobile Message "The phone that you are using does not allow outgoing calls."

After changing a few settings on my T-mobile plan (unblocking Spam), I cannot call out of my iPhone. The message that I hear is "The phone that you are using does not allow outgoing calls." The message that people here when they try to call me is, "At the subscriber's request, they do not allow incoming calls." Yes, I have rebooted my phone. Yes, my bill is up-to-date. I cannot call out using Wi-Fi calling either. I can text. My son, also on my account, is having no issue; he also has an iPhone. Anyone have a solution? I rechecked the setting that I change on the website earlier and nothing looks strange.
