Problem setting up iphone 16 pro max with wi fi calling

I get the following error message setting up wifi calling. I might add that I hooked up my wife's Android with no problems here at the same address



{"code":"ERR-SUB-

4000079", "message":"Attempted transaction failed ir [{"code":"CPS.SVC-0001", "message":"Invalid request. not valid in URI, Query or body.", "source Application":

action failed in downstream application processing", "causedBy". valid request. Input parameter(s) \"houseNum\" is not found or eApplication":"CPS", "severity": "ERROR"}]}

iPhone 16 Pro Max, iOS 18

Try without using any abbreviations such as St. or N. Also check on your carriers website, for example Verizon has a privacy policy that must be agreed to and also suggestions if the E911 address does not match. They recommend checking the USPS database to confirm the listed address.

I don't know what the difference would be with your wife's phone and your phone implementing the E911 address when using WiFi calling.

Since WiFi calling is just a switch to turn on, it is not clear what you mean by "setting up WiFi calling" other "hooked up my wife's Android with no problems hare at the same address".

  • Are you attempting to use a particular app other than the Phone app for calling?
  • Have you tried resetting your Network Setting on your iPhone?
  • Have you tested with a different WiFi network?
