Since the iPhone 2.1 upgrade, half of the calls to my iPhone do not cause the phone to ring at all. Instead, I get a notification later that there is a voicemail (if a voicemail was left).

The ringer is switched on and the phone does ring sometimes... but only sometimes.

I am sitting here at my desk at work and have full strength on AT&T, so I'm not even moving around, yet the phone doesn't ring half the time.

Rebooting didn't help.

I'm also having intermittent problems where SMS messages are taking hours to arrive at my phone, although this problem seems to have gotten better in the past few days.

I'm wondering if this is some kind of AT&T problem...

    I'm having the same problem. This didn't happen before the 2.1 update, so it seems like a bug.

    This started happening to me just today. Doesn't seem to be related to the new update as it worked great until now. Another gentleman here at work is having the same issue. We're frustrated as it is hindering our ability to get work done.

    I just did a couple of tests with my wife's iPhone and mine together during lunch today. Both phones are "original" iPhones running version 2.1, and both had plenty of AT&T signal strength.

    Test 1: A calls B -> one ring, then straight to voicemail.

    Test 2: A calls B -> no rings, then straight to voicemail.

    Test 3: B calls A -> no rings, then I end up in some random voicemail menu where it starts telling me "The blahblah delete feature has been added to your voicemail. BlahBlah...".

    At this point I was getting more and more incredulous and agitated and my wife gently reminded me that we were supposed to be enjoying our lunch together instead of debugging AT&T's stupid phone network.

    I will continue further testing later...

    Myself and the other gentleman at work here are both using 2.1 on original iphones as well. Mine is the 4gig model and his is the 8gig.

    Incoming Calls - Directly to voicemail
    Outgoing Calls - Silent (never actually says connected on the screen)

    This kinda goofed me up today as I was waing on a call from my doctor and he could only leave me a voice message (which I got hours later). Both myself and the other guy here are losing a lot of productivity time from it as well.

    I would have to say I believe it would have something to do with AT&T. However, there are a few troubleshooting tips to try for the iPhone first. Try to power off/on the phone, then try a reset, hold Home and power off/on button until you see the Apple logo and release. Before you try a restore, you might want to take out the SIM card and re-seat it. You can also call AT&T CS and have them check your account. Something could have happened there (a bug) and they can correct it at their end. If you are close to an AT&T Corporate store that handles the iPhone, you may want to go in and get a new SIM. This can cause problems and I have seen replacing it work. Hope this helps you.

    I had this same problem but only after I had turned my bluetooth on. Once I turned it off, everything worked normally again.

    I called Apple before figuring this out, and they had no clue what the problem was but agreed it was not an ATT problem.

    On my iPhone, Bluetooth is not enabled and hasn't been for a long time.

    Since last post I've had the following additional problems:

    - I was unable to send an SMS message. I tried four times (three times yesterday, once today) and it never went through.
    - My wife sent me an SMS message. I received it THREE times. She only sent it once.
    - My iPhone has reported "visual voicemail is unavailable". Then it came back.

    All of these problems occurred in locations (home or work) where I have never previously had problems until this past week or two.

    Been having this same problem for a couple weeks now. I'm not sure when it starts as usually I have no idea something is wrong. I'll get an email from someone saying "I just tried calling you... and went to voicemail", or I'll wake up in the morning and see that I missed 3 phone calls from the night before. Service seems to magically start working as mysteriously as it stopped. I just tried restarting my iPhone, it started working fine. Then about 10min later it stopped working. A reboot of the phone seems to work.. temporarily. I would think this has something to do with the 2.1 update. I don't believe I've ever had a problem like this before. I've had my iPhone for a year now.
  • ChrisJ4203 Level 8 (47,694 points)
    I would say that if you have tried the normal troubleshooting steps for the phone and a restore, which is the last step, has not corrected things, I would make an appoitment at the Genius Bar to have them check the phone. If the phone gets replaced and still exhibits this problem, then I would contact AT&T about getting a new SIM card. The SIM controls your connection to the provider's network, but a hardware/software problem with the phone could explain a disconnect between the phone and the provider. If a restore from backup doesn't work, remember to try a restore as a new phone. If that does't work, that is the last step before going to Apple. You can make an appointment at the local Apple store on line at

    Hope that helps.

    Turns out this is happening in a small coverage area here where I live. No ATT phone is able to connect. My problem is not iPhone specific and is therefore, an ATT problem.
  • KGB1966 Level 1 (0 points)
    I am having the same issue, however, the phone will ring if the time it has been in sleep mode is less than 1 minute. Over 1 minute and it will not ring. Also, my wifi is not working.

    Anyone have thoughts?

    I have been having this issue with my wife iPhone on our family plan. I called AT&T and they said everything is fine on their side. 50% of the time when I call her or anyone else call her the call go to voice mail after 2 rings from the caller side (the iPhone actually never rings). On the other hand, when I call her other AT&T number, which is always forwarded to her iPhone number, the iPhone rings normally without issues. I even tried using the iPhone SIM with another AT&T and GSM phones and got exactly the same result.
    It seems there is something wrong with AT&T SIM card or service not the iPhone itself. It cannot be coverage since I tried the above at the same time and location again and again and my iPhone is working without problems. It must be something with their setting since there were problems with voice mail when we first got the iPhone. If anyone got their iPhone to work correctly after replacing the SIM card let me know. I don't want to drive an hour to AT&T store without confirmation first.

    Just wanted to say that I have the same problem... Phone with good signal but no ring and straight to voicemail. Also I have 3G turned off. With it on, I get no signal. I thought it was my location in Tampa... But it did work in O'Hara Chicago and elsewhere.
  • cronnicj Level 1 (0 points)
    I have the same issue. Calls do not show up, phone does not ring and then I get a missed call or voicemail later. I just 5 voicemails left of the past 2 days all at one time.
