When I try to click on advanced calling in connection settings, the advanced calling screen flashes up for a second and then I'm returned to the previous page. If I try to click advanced calling again, nothing happens.
If I kill the settings app and try again, I get these same two results. I've tried starting in safe mode, same result.
What is preventing me from accessing these options? I can still use wifi calling (I was prompted to turn it on by my phone), but have no control to turn it on or off as desired.
The connection to the Verizon Wireless network might not be able to work if it is off anymore.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
