Wifi calling not functioning

Have you checked to see that enhanced LTE services is on? If it is already on they try and toggle it off then back on again.

It's under settings, connections, mobile networks.

Just tried powering enhanced lte services off and on... Then tried powering
wifi calling off and on. No change.
😞

Are you a prepaid customer?   Prepaid has not yet activated Wifi calling.  

 

No my phone is under a monthly phone plan

That doesn’t really determine prepaid, as prepaid also offers “monthly” plans.  Please post the name of your plan, it’s on your bill.    

If you can’t enable advanced calling features on AT&T, you either are not in an HD voice area, or don’t have an HD voice enabled plan - which usually means prepaid.  

 

I am 100% positive I am not on a prepaid plan my father holds the account
and is paying for 6 + devices on a 15gb monthly with unlimited talk and
text. I dont have the bill in front of me to give confirmation, but I know
that I was previously, by this I mean since I first day I received the
phone, I was able to use wifi calling as long as I was connected to a
strong wifi network.

AS for being in an HD area I was able to use Wi-Fi calling when I was at my
school last semester. Still living in the same building and room which I
was able to use wifi calling in. So i highly doubt I somehow lost the
ability over the span of one month at home

You said in the beginning that this problem only started after an update, so has nothing to do with the type of account you have with AT&T.

The best would be to call 611 from the affected phone and to get the folks there to check into it for you.

When you wiped the cache can you confirm that you did this from recovery using this method

 

1. Turn off the device.
2. Press and hold the Volume up, Home, and Power keys together
3. etc. etc.
