Phone switching from wifi to cellular and dropping call, but wifi calling is OFF
Recently my phone has been dropping calls before I answer or before the person I'm calling answers. There is a brief message that says the call can't be continued over wifi and is switching to cellular. However, I DO NOT HAVE WIFI CALLING ON. This is very frustrating. I have to call twice and the person I'm calling usually sees that I called and may be trying to call me back. Likewise, if someone is calling me and it hangs up, then they go to voice-mail and have to call back. I have checked all settings regarding wifi calling and all are off. A search of this issue does not provide any results, but there does seem to be a lot of dropped calls on all networks when switching from wifi to cellular or vice versa. But, these users have wifi calling on. I do not. On S10. Not sure if this is a phone problem, an android software problem, or a network problem. Anyone else having this issue? Just seemed to start a few weeks ago.
