Mobile Data Not Working While On a Call
I don't know why but about a month ago, my mobile data stopped working while I am on a phone call. I have an iPhone XR and I'm on the Xfinity Mobile unlimited plan. If I try to use an app or surf the web or get email while I'm on a call, I get a message that says "cellular data is not available during this call".
I called Xfinity twice about this and they told me that Xfinity does not have the abililty for data usage while making a call. This, of course is absolutely wrong and why TWO different tech support reps told me this is just unbelievable. Anyway, my girlfriend pointed out that in "settings" > "cellular" > "cellular data options" > "voice & data" you have to have "LTE, VoLTE On" needs to be checked. Once I checked this, my problem went away and everything worked as it should.
Someone please tell the tech support reps this basic tip and save others from wasting their time.
