How to fix “The phone number is change or not in service” message when placing calls on Sprint.

iPhone running iOS 8.3.

I ran into an issue after enabling Wi-Fi calling in my Sprint iPhone – It would not place or receive calls as soon as I left Wi-Fi or even when I came back on Wi-Fi.

I would keep reciving a message along the lines of:

“The Phone number that you are trying to call is disconnected or not in-service. If you received this message by error then, check your number and try again. (Error Number).

The wired part was that I was able to call 5-1-1, Apple Care and, Sprint Care or any Toll-free number. I was Just not able to call a local number.

I called Sprint and went to a Sprint store but, all they were able to do was ##UPDATE# and then ##CLEAR#. The last operater from sprint told me that it was a “glitch” in the network and If I summited my location to them then they would come to the tower and fix the “glitch”.  Keep in mind that the problem started on a different tower. He told me wait till the morning and call back if the problem was still there.

I decided to take the problem into my own hands. I went into Setting > Phone > WiFi Calls > Update Emergency Information > Scrolled down and checked “Disable Wi-Fi calls on this account > Confirmed the print and now the Wi-Fi calls were disabled from the Sprint system – The Problem went away.

UPDATE (No idea with date it is):*The phone number is change or not in service* has been fixed with a carrier update and in iOS 8.4. If you are still on iOS 8.3 then call ##873283# to fix the problem while using Wi-Fi calling.

UPDATED: Sprint Enables Wi-Fi Calling for iOS device with iOS 8.3!

UPDATE 4/17/2015: Do not enable Wi-Fi right now. I have gotten a statement from a Sprint Representative that there is a known problem where If you enable using your iPhone and leave the Wi-Fi then your phone will not be able to make calls if you are on Wi-Fi or not. The way to fix this is to not use it now or go to your online Sprint account and add the Wi-Fi calling feature manually – A Sprint Represenative can also do this for you.
If you do not want to add it to your account then you can disable Wi-Fi calling permanently (Not using the Toggle) then there is a guide here: Click Me!

With iOS 8.3 Sprint also sent out an carrier update (19.1). This gave iOS users the option to use Wi-Fi Calling for Sprint Users.

If you want to enable Wi-Fi calling then Go to: Settings > Phone > Wi-Fi Calls > Enable “Allow Wi-Fi Calls” > Tap “Turn On” on the Prompt > Verify your address (or fill it in) > Tap “Next” > You are done!
You will now have a option to “Update Emergency Address” – This is the update the address you put in or verified; which will be shown to the Emergency Services if you call 9-1-1 using Wi-Fi. Always tell the Emergency Services your EXACT location in case of any emergency*.

What Wi-Fi calling is if you don’t or have poor network connection in an area then you can use a Private or Public Wi-Fi network so your calls can be directed over Wi-Fi. There are some limitations:

Only the following Abbreviated Dialing Codes (ADCs) are supported over a Wi-Fi Call for iOS. Dialing another ADC (*55 for example) will result in a message stating the call cannot be completed over Wi-Fi. This call will need to be placed after the Wi-Fi Calling feature is turned Off.

With Wi-Fi calling the Phone will try to use the cellular network to connect to emergency services like 9-1-1. If the call cannot be make because the single is poor or in-existent then it will be made over Wi-Fi. Emergency services will not be able to tell your location if your call is made over Wi-Fi so, you will have to provide them the exact location in an event of emergency.

All messages will still go over cellular network for now. If are not able to get a cellular connection then you text messages will not be sent.

All Wi-Fi calls are free and will not count against your call minutes if you do not have a unlimited plan.
