the sim card either connects or it doesn't, there are no audio channels going through there
it is not your sim card

Sony should really do something with its quality control... The best if move production from china to Japan.

sorry mate but I strongly disagree with this - this is not a fault with the sim card - the sim card works or it doesn't there is no inbetween and the sim does not carry audio it simply connects to carrier network the phone delivers and recieves all the signals, putting anything in there (bits of paper) have the potencial to remain in there and cause a problem
do not do this under any circumstance

At least it solved my problem.
By the way, I guess you misunderstood my method. It is to make the sim has full contact with the chip in the phone because some sim cards are thinner in thickness. The paper is between the sim and its removable tray. It will be about the same size as the sim and how it is going to be stuck inside?

First try disabling Settings -> Call settings -> Microphone noise suppression and see if that helps.
If not, try setting the phone to GSM only/WCDMA only under Settings -> More -> Mobile networks -> Network mode. Does the problem occur regardless of which network you use?

I did all those when I had the phone. Nothing worked.
Anyway, the problem is fixed, I returned the phone and got a replacement. Everything works perfectly now, really enjoy this phone.
Thanks to all who tried to help.

I am having this problem after 8 months of purchase. I have tried the mentioned activities but no use. I am using the sim card from 2 years from xperia s, but never i encountered such problem.
Its getting really dissapointing. No settings is helping

I had the exact same issue after about 8 months ! I tried fixing it , but after a few weeks it just disappeared and now my phone is working again ( alsmost ) as it should. I'm hoping this problem stays fixed and not pops back up again after my 24 months of warranty .. Which would **bleep**.
New bug I found, I think after the android 4.3 installation, is whenever I pick up a call the phone automatically puts on the speaker .. Time and time again I have to turn OFFthe speaker.
Does anyone know of a possible setting ? Or is this really a software bug?
