Q: incoming calls ring on multiple phone numbers

Agreed, let Apple know:

Thank you! That solved it.

Thank you! That solved the problem.

This poor little bunny is confused. I am not sure I see a solution for my problem here so far but maybe one of you smart people can help.

I have a US SIM and a UK SIM (where I live). Usually I take the US SIM with me to the United States and it becomes my iMessage and my Facetime phone number. When I look at the list of places I can receive messages and facetime calls, it lists only that phone number and also my icloud email address.

Recently my wife has gone to the US and made use of that same SIM card. I assume she went through the same thing of allowing iMessages and Facetime to use that phone number when she was there. AND, as I always do, switch back to her UK number when she comes back home.

Well, on my recent trip to the US by myself, every time somebody facetime'd my wife it rang her phone AND my phone. She was in the UK and I was in the US, so it had nothing to do with handoff. And we each have our own iCloud accounts (although she is using a phone I used to use ... but it was reset and restored with her data on it, so I doubt that's it).

I thought, I can solve this problem by running facetime explicitly on a particular phone number, but that doesn't seem to work anymore. Instead, there's just a Facetime link in the contact that you're supposed to press. I cannot imagine why this is ringing both our phones at the same time, on different continents.

EXCEPT: the people doing the calling have that same phone number in TWO SEPARATE ENTRIES in their contacts: one for me and one for my wife.

Could that be it? Could it be looking at the phone number, coming up with two icloud personalities, and ringing them both?

If you have insights, I am much obliged!

[Added later]

I just realized even that doesn't make sense. Right now we're both in the UK using our UK numbers. People are Facetime'ing my wife but they can't be using that US number to do it because it's not registered on imessage for either of us right now. Yet it continues to ring both our phones! Now we're in the same house, but ... Oh my.

Worked like a charm.

Thanks!

My phones are legitimate, too.  This helped right away. 

Using a different ID is not practical. I use the same AppleID as other people for a very good reason. Find my iPhone. I can instantly see where everyone is. Secondly if I create a new ID, what will happen with all of the Apps downloaded and purchased over the years? I am sure they will be lost because they belong to the ID under which they were created.

You can use Find my iPhone with different Apple  IDs. And also share apps and music among those IDs. Family Sharing - Apple Support

In addition to what Lawrence suggests, you can also set up and use Find My Friends to know where the others are.  Instead of Family Share, you can also use a common ID for purchases and separate IDs for iCloud -- you can have more than one ID and it is painless to set up and nothing to maintain.

Why are you asking people to stop using a feature they have used for years to prevent a clear bug from happening? If I use different IDs for every device then what happens to all of the apps purchased? Find my iPhone shows all of my devices on the one screen , I don't need to log in and out with different IDs. So I need 10IDs, 10 new passwords and security questions? It's absurd. I fail to understand why Apple keeps connecting devices which use the same ID and yet have different phone numbers. It's completely illogical. And why anyone would want their call list replicated on another device is beyond me. Also can't understand who would want more than one device to ring at the same time. It's plain dumb.

Because a feature you have used for years has been augmented with a new feature called Family Sharing. But if you don't want to use it you can still solve the problem.   This is a feature called "continuity." You can answer any device from any other. If you don't want it go to Settings/FaceTime on each phone, turn it on if it is off, then turn off iPhone Cellular Calls. You can then leave FaceTime on or turn it off, as you desire.

I find it a very valuable feature, as I can answer my phone from my iPad, my iMac, my MacBook Pro, or my backup iPhone. And also initiate calls from my computer without pulling out my phone. Which is why I'm happy Apple provided it. But if it doesn't meet your needs, simply turn it off.

Lawrence I have turned it off on all devices some weeks ago and thank God this annoying "feature" has dissappeared. I have heard similar complaints from colleagues that have for example a German SIM card in one iPhone and an Austrian in the other. It annoys the **** out of them when both ring especially since one is in international roaming. Really this feature causes much more trouble than good.

The replicated call list problem currently has no solution . Or do you have any ideas other than creating new IDs which is impractical.

You're not paying attention.  You can use one ID for purchases for all devices -- that way all the apps you have can continued to be shared across devices.

For devices that you don't want iCloud/continuity features to be shared, set up separate IDs just for iCloud (keeping the common ID for purchases).  These extra IDs are a one-time set up, and you don't need 10 different passwords -- use the same password for all for simplicity.  As far as security questions, that I believe is optional, but if required would be a one-time setup and you can use the same questions/answers for all IDs.

Going this route DOES address the call list issue you mention -- my wife and I share an ID for purchases, but use separate IDs for iCloud and we do not get each other's call list.

This continuity feature is great, I happen to love it for my iPhone/ iPad, and Mac, and so do many users (which is why it was developed).  If you don't like it or find it cumbersome, then you have simple workarounds to get what you want.

I Personally have iPhones with German, Austrian and Australian SIMs and they are always turned on. So Apple is saying that it is a good feature to make all phones ring , regardless of which country you're in. Imagine the roaming costs incurred due to Apple's "feature " . Whereas I can understand linking an iPad and iMac to the iPhone, iPhone's using the same ID clearly have different phone numbers connected to them (possibly even with SIM cards from differrent countries in them - as in my case) and hence should never be connected in any way whatsoever.

SO you are saying I should create different Apple IDs for each iPhone (which are all mine but have SIM cards from different countries in them). This seems so inefficient. Look anyway there is a workaround for the "phones ringing at the same time problem". But not for the "recent call lists replication" bug. This is a bug, definitely not a feature, and should be fixed.
