Can't receive calls on locked iphone after 2.0.1 update

since i updated my original iphone from 1.4 to 2.0.1 firmware, i have the following problem: when the iphone is in use, it receives calls just fine. but once the phone is locked (that is, the screen is black), all of a sudden it can't receive calls anymore. it does not ring or vibrate. only after it is unlocked again, i get a "missed calls..." message. any ideas?

Actually, it appears there is an issue with 7.1.1 which a lot of us are experiencing. See here:

Ios5.0.1, can't receive calls, can't end call, can't take video!!!!!

After installed ios5.0.1, can't receive calls, can't end call, can't take video!! The screen become frozen! Any help please? Thx!

How about going to a corporate store and see if they will let you put your SIM card in a display model. Your number will transfer over with the SIM card. Then if you call your number from your wife's phone or one of store landline phones and the call goes through, you have ruled out the SIM card being the problem.
You don't have the phone number set to automatically forward to the voicemail, do you?

When calling or receiving calls, after a minute or so, is the call, give notice "call failed, THEN RUNS OUT OF SERVICE, then activated" SEARCHING "and then restoring the coverage. THIS FOR THE 100% of calls

You may have a bad sim, contact your phone carrier and see if you can get a new one.

this time 8.1.2
Today was 1 minutes call, by calling was 4-5 disconnect episodes

IT'S a SOFTWARE PROBLEM!!!!

          - Check for a Carrier Settings Update. Tap Settings > General > About.

          - Find out if there are specific error messages in the carrier logs that could help determine why the issue is occurring.
If none of the above steps resolves the issue, contact your carrier, make an appointment at an Apple Retail Store, or contact AppleCare to troubleshoot further.
Thanks,

I just got this phone last night and I can't receive calls. It was my sons phone and it worked perfectly before.

My son got a new iphone5 so I took his iphone4s. It worked perfectly with him but, after I activated my new SIM card and try to use the phone I can't receive calls. I can make calls and sent and receive texts. Just can't receive calls.

try resetting your network settings, it just resets wifi and carrier settings, no data

IPHONE 5: can't receive calls & random error messages, such as "could not activate cellular data network" and "no connection - network unavailable, please connect to wifi or cellular network." This occurs even when signal strength or wifi is operational.

IPHONE 5: can't receive calls and random error messages, such as "could not activate cellular data network" and "no connection - network unavailable, please connect to wifi or cellular network." This occurs even when signal strength or wifi is operational, and it does not matter whether wifi is on or off. ATT went through the standard protocol - resetting network, resetting sim card, etc. No changes. Other phones working fine in same region with same carrier. Apple's solution is to restore software, but haven't gone there yet. Anyone successfully addressed this/these issues?

I should point out that it worked when the iPhone was set back to factory settings, but when restored with the backup, data/internet no longer works again, and I get the "Could not activate cellular data network" error message yet again.

Nokia E5 - Can not hear Caller after disconnecting...

When i disconnect the phone from the VW car kit, i can not hear a caller when they ring me, the phone does have the car symbol on the bottom status line and the only way to fix the problem is to restart the phone everytime i disconnect from my car kit....not ideal !!!
Any ideas on why it seem sto think it still connected ?
Regards
mark.

Okay! If you have the same problem, you end all runing programs in the taskbar. reset the phone several times. i can hear the caller after that. hope that the problem comes not back.
There ist the Problem with the battery!

If someones is using my account/apple id can they receive calls or messages too?? and how can i notice if someones using my apple id??

if someones is using my account/apple id can they receive calls or messages too?? and how can i notice if someones using my apple id??

You cannot make your @icloud.com address the login address for the ID. However you can change your ID, currently a Gmail one, to any other functioning non-Apple email address. The Gmail address would then no longer access your account, and so even if someone were to obtain posession of it (is that even possible) it wouldn't allow them to get into your account.
If you want to change your ID to another email address please follow the procedure outlined below, particularly noting the first step.
Firstly, if you have 'Find My iPhone/iPad/iMac' enabled on any of your devices, turn it off.
Create a new email address, for example at Yahoo or Gmail, or anywhere convenient (or you can use an existing address as long as it has never been associated with an Apple ID).
Go to http://appleid.apple.com and click 'Manage your Apple ID'. Sign in with the current ID.
Where it says 'Apple ID and primary email address' and gives your current ID email address, click 'edit'.
Enter your new address and click 'Save changes'.
Now you will need to go to each of your devices and sign out in System Preferences (or Settings)>iCloud - 'Sign out' on a Mac, 'Delete this account' on an iOS device (this will not delete the account from the server).
Then sign back in with your new ID. Your iCloud data will disappear from your devices when you sign out, but reappear when you sign back in.
I re-iterate: before you start, turn off 'Find My Mac' (or whatever) or you will need the services of Support.

URGENT: iphone 4 hang, can't power down, can't receive calls, can't do anything

I've been using my iphone 4 for more since I got it when it came out 1.5 yrs ago with hardly any problems.
I updated to OS5 few weeks back and was totally Ok until today, I started my gmail, and the phone froze and the swirling symbol is going next to my full WiFi Access and ATT 2 bars signal strength.
It's been more than 30 mnts, and can't receive calls, can't power it down, and nothing I pressed or did seems to affect the device.
What do I do?

Well, first, you can't revert back to OS 4.x, and second, a search of the forum will quickly show you that this could happen with 4.x, 3.x, 2.x and ever the original iPhone Classic.
And don't think of the iPhone as a phone; it's a very powerful pocket sized computer that can also make phone calls. And it can suffer all of the things that happen to any computer, like the Windows Blue Screen of Death and the Mac OS X kernel panic (which is what happened). It happens when memory gets full (RAM, not storage) or when one app steps on the memory of another. You can minimize the chance of it happening by turning the phone off occasionally, which shuts down all of the apps.

I can't receive calls

I bought a Noki 2760 mobile phone yesterday.
I can't receive calls. I believe I have closed the loudspeakers or shutdown receving calls.
I can call you and I can send SMS to you.
I tried in vain to solve the problem.
I have downloaded the English manual too.
Please help me to fix the problem.

Hello and Welcome to the Forums!
Given your description, I believe your suspicion is correct -- something wrong with the account tied to the SIM that is not working. I suggest contacting your carrier for assistance.
Cheers.

I recently changed my password for my Apple ID and now I can't receive calls on my iPad or Mac. All devices are signed on with the same iCloud account. Anyone have the same issue?

Hello!
On all of these devices, go to: Settings > iCloud and make sure they're updated with the new password. If you're talking about Macs, go to: "System Preferences > iCloud" too.

the screen on my smart phone is broken, it still works, I can here my received text sound. Can I receive calls on my tablet or pc?

IF you have installed/activated Verizon Message+ on your phone, then yes you can. If not, you are out of luck.
If they are iMessages on an iPhone, you could log into your iMessage account on an Apple computer to read the iMessages, but would be unable to view SMS/MMS.
