Sorry, you can't. Design change with iOS 7.0. Tell Apple you don't like this here:

I can't make/receive calls on days old iPhone 4. Just says Call Failed.

Same thing is happening with my girlfriend's 3Gs. The person being called hears half a ring then phone cuts out. I have all bars but when call fails bars all drop for a moment, then return. I've reset network settings and everything else. What the **** ****!?
Not sure if it's an AT&T issue, or iPhone or both. I drove out of town and was able to make calls again. Once i returned the problem resumed. I called AT&T and they have no knowledge of network outages in my area. My girl's co-worker (also an iphone owner-3Gs) is having the same issue.
I put up with AT&T's horrid service with crappy coverage and failed calls all the time but this is far worse. I CAN'T USE MY PHONE!
Somebody please help me before I murder this thing and buy a Droid X.

Thank you for your reply. Unfortunately, it does not make a difference. It still shows "iPhone not available. iPhone and Mac have to be in the same network"
Are there any settings which are fundamental on the iPhone, I have activated:
- iCloud Drive
- FaceTime (FaceTime and iPhone Mobile Calls activated)
The only strange thing - on Yosemite I can activate mobile phone number AND email in FaceTime whereas I can activate just my email in the FaceTime app on my iPhone...

Thanks this was very useful.. I have a brand new iphone 4s unlocked version from singapore and I am having the same problem constant network fluctuations, no service, call failed, invalid sim, sim failure, bars fluctuating from 5 - 3 - 2 - 1, no signal/ba

I have a brand new iphone 4s unlocked version from singapore and I am experiencing constant network fluctuations on my iphone , no service, call failed, invalid sim, sim failure, bars fluctuating from 5 - 3 - 2 - 1, no signal/bars searching etc... Ifeel miserable after trying out all the options changed multiple sims, tried multiple carriers, restored the phone back and have set-up as new device but the problem does not get solved... its is so frustrating that after investing on a world's most expensive phone you cannot enjoy the calling features which the phone offers which is the main thing you own the phone for.. Rest of the things are working.. The funniest part I am not able to make calls or receive calls but can access the internet.. I have tried every possible thing and really very frustrated with this iphone of mine...I hope the problem gets solved.. would anyone have any solutions to this problem.. Does it mean one should never update software as I hear that after updating to IOS.5.1 the problem has started coming and same has been with there.... Apple says its a hardware failure which is very difficult to digest as sometimes I get 5 bars and able to make and receive calls but 95% of the time I am unable to. If anyone has any solution I will be very happy if he or share can share the same. Many thanks. its so disgusting to experience this on top of this apple does not support global warranty for the phone as you need to go to the country from where you bought the phone for replacement.. Truly sad state of affairs.. very very very dissappointing.

My wife and I both have iPhones recently when someone calls her phone mine also rings. How do I stop this?

Both my wife and I have IPhones (5C and 4S). For some reason for the last several months when someone calls one of our phones it rings on both phones. It seems to have started with the OS updates but that may be a coincidence. Is there a way to stop this?

DrYes wrote:
So if I turn off IPhone Cellular calls this will eliminate the problem? As I read it the double ringing only occurs when we are signed in and the phones are close and connected to WIFi.
Correct, I wouldn't lead you astray with a false response. It happens because you and your wife are using the same Apple id for facetime - which you shouldn't do, either you or her will need a separate id for facetime.

It is not practicale to do this always any one faces the same problem

There may be a problem with the SIM card. Get a new SIM card from your carrier - there should be no charge for a replacement.
If no change with a new SIM card, the standard troubleshooting steps in order are:
Power your iPhone off and on.
An iPhone reset, which is done by pressing and holding the home button and the sleep/wake or on/off button simultaneously until you see the Apple logo and then release.
Restore your iPhone with iTunes from your iPhone's backup.
Restore your iPhone with iTunes as a new iPhone or not from your iPhone's backup.
If no change after any of these steps in order, your iPhone has a hardware problem.

I have recently upgraded to iPhone 5 from 4, call line identity doesn't work when call other iPhones. It works when calling any other brand of cell phone. Network carrier assures me problem is not on there side. Any assistance will be appreciated.

Hello ram tough,
Thanks for the question. After reviewing your post, it sounds like the iPhone is not receiving some calls. Are you having trouble with visual voicemail? I would recommend that you read these articles, they may be helpful in troubleshooting your issue.

Updated my iphone with iOS7.0.3, still dont have the option to reject the call or reject the call with a message when someone call and the phone is in the lock screen?

Updated my iphone with iOS7.0.3, still dont have the option to reject the call or reject the call with a message when someone call and the phone is in the lock screen? I was of the impression that this issue will be fixed with updates. Please see the screenshot.

Hello Beardsell,
This is when the phone is unlocked mode. My snapshot is when the phone is locked.
Remember when you get a call when the phone is locked and you used to have slide to answer in iOS 6 and if you slide up you would have options to reject, reject with a message and reject with a reminder. We dont have that in iOS 7. iOS 7 *****, I cannot get back to iOS6, apple needs to be user friendly. Screen shot 1 when the phone is locked, screenshot 2 when the phone is unlocked.

Hi, I have tried to use FaceTime using both my Mac and iPhone, it showed it was connecting, but can't not be connected, and it will just show call failed. could you please look into it? thanks

Hello Mogulman46,
So what that means is when you have Do Not Disturb turned on, you may have an alert depending on the setting and how you are using your iPhone. So if it is set to Always, then that means that no matter what, your iPhone will not be notified. If it set to Only while the iPhone is locked, then that means that you will not get notification when your iPhone is locked but you will get notifications if your iPhone is being used. Also keep in mind the settings All Calls From can be set to certain contacts like Favorites, Everyone or no one. If you are using Do Not Disturb and you do not need it, then turn it off.
Use Do Not Disturb on your iPhone, iPad, or iPod touch
