    the first few calls I made on At&t with the 4S did the same thing...
    not sure why, but it seems to be better now, hasn't happened anymore.

    Saw the problem with a phone given to someone at work.

    He went to record his personal voicemail greeting, and no matter how loud he spoke, it wouldn't record anything. So then he called my desk phone, just to test, and I couldn't hear him.

    Had him record a voice memo, and it worked fine. From that point on, his out going calls worked.

    Sounds like a very crappy software issue. :(

    I am having the same problem. Talked to an Apple specialist tonight and he tried a network reset. That did not work. He said it sounds like I have a bad SIM card.
    I did receive an email from APPLE that my phone came with a defective sim card. I will receive it tomorrow and replace it. Hopefully that fixes the problem!!!:confused:

    Same with my phone. It would only work on speaker for some reason. Waltzed into AT&T and they swapped it out no problem. Actually I called ahead and told my friend who worked there to hold a white 32gb phone for me.:D

    Gee, you think there's a connection? :)

    I'd suggest any others with the trouble get in touch with their carrier customer support.

    I'm just now having this problem with my iPhone 4S. A little bit of static, then they can't hear me.

    So this is a defective SIM card problem???

    Re: Iphone 4 people cant hear me during calls.

    iPhone 4 1.5 years old.
    I honestly believe Apple is lacking in customer service intentionally, knows the answer to this issue, and chooses to ignore it as there solution so far is a win/win situation for them.* By not correcting what seems to be a simple problem, they admit no error in phone design.* The fix offered is replacement either under warranty or not.* The win/win?* Apple avoids losing a client to competitors such as android based phones, keeps the client for the remainder of the contract due to costs involved with breaking the contract, or gains a new 2 year commitment via the service provider contract.
    I have the sporadic problem where people can't hear me.* They always say "static" is heard before my voice goes silent or I can't be heard at all after receiving or making a call.* After trying all the fixes such as the paper spacer, starting /stopping iTunes/restarting phone, factory resetting phone, pressure on the back of phone, making sure all screws are tight, the one that usually succeeded in curing my silence during a call was pressure to the back cover?
    Mine is not a software problem as physical solutions correct the issue.
    After testing the many options above, I noticed a "lever" to the lower left of the battery which is a part of the hold down for the battery connector.* This lever also aligns with a "metallic" 1/4" by 3/8" rectangle on the inside of the back cover.* I assume this is a back screen anti scratch patch, ground, or tension/distance/pressure/spacer lever?* The lever actually sits higher than the remaing profile of the insides of the iphone and is compressed when the back cover is attached.* I have no clue why the lever is there but think it is part of the problem?* If anyone knows, please comment.
    Anyway, I found that while making a call with the back cover off the phone, all could hear me regardless of making or receiving a call.* To be specific, no outer shell contact with the inner hardware.* After thinking through, the paper spacer makes sense as it releases pressure or completely removes contact of the lever from the backing.* My reasoning for suspecting the lever is a tension/distance/pressure/spacer sensor is due to my voice being heard after pressure being applied to the back cover.* Some will say the I am simply "reconnecting broken solder connections.* I would agree except for the fact that the profile of the hardware is flat as is the back cover and technically, there should be no contact from hardware to cover* This would indicate the lever is there to keep the internal hardware from contacting the back cover of the iPhone.* So, my applying pressure to the back of the phone shouldnt factor into solder reconnections as there should be no contact and the functional operational oif voice calls with the removal of the back cover eliminates the solder connections reconnected idea.
    Further, it would seem since callers and called can hear me once the back cover is removed, the problem is related to "distance" or "contact".* I believe the rear phone cover is contacting internal hardware or the battery lever in a way that causes a "bridge" connection that shorts out the "phone" part of the microphone only.* Proof of this is the continued operation of the microphone with software such as "recorder" or "dragon dictation" when people cannot hear me talking during phone calls. Further proof is the "static" heard by callers before my voice goes blank indicating interference of either a physical or electrical source.
    Possible causes are:
    Aged battery.* Lithium batteries are notorious for "bubbling" after repeated charges.* This would cause contact since the battery is trying to occupy a larger space as it has "grown".
    Dropping the phone has "bent" or moved internal parts causing internal contacts.
    Antenna shorts?* Do the 2 antennas also have separate send/receive designations which would indicate one of the antennas working and the other not due to internal contact?* This would support being able to hear callers but not be heard.
    Please let me know your results.

    This is exactly the problem (and solution) that I've been having lately.
    I tried to restore the phone, upgrade it, and even tried the paper method but it still gives me the same problem.

    I think something's loose in the phone because I remember dropping it a few days before the symptom started.
    I will try to open the phone to see if your observation is correct.

    Keep me updated! I will let you know if I could fix this.

    I read this and it made sense so I talked on the phone managing to never touch the back (it was difficult) and it worked the could hear me the whole time.
