I also updated my iPhone to 6.1. It did not change anything about the call quality.
Still chopy and robitic voice.
Do not know what to do now.
Going back to Mobistar, change the phone, 2 weeks no phone and hope a second change will fix the problem...
I loved Apple for his great products, but the love for me is over.
I have also updated to 6.1.
I have earlier described three symptoms: 1) low sound being cancelled (overly active noice cancellation?), 2) muffled sound and 3) choppy/static sound.
For the time being I have not experienced 1) after upgrading. But since the symptom varied a lot from place to lace I can not conclude anything definite.
What I do experience (with a vengeance) is 3); the sound is so clipped and static that it is almost impossible to have a conversation. This is experienced by both me and the person I talk to. The problem is so prevalent that people refuse to call me on my iPhone (uses work phone or skype instead).
I had more problems with symptom 1) and 2), now it is more symptom 3).
I can add that I did several test calls with an old Nokia from 2003 and swapped the sim-card back and forth between this phone and the iP5. The sound on the Nokia was not clipped and was much less muffled than iP5.
My colleague has an iPhone 5 (purchased through Three, Ireland). Exceptional call quality before 6.1 and after uprgade. I've bought all of mine online from Apple Store Ireland with delivery from UK and both sounded dreadfully bad with same pay-as-you-go plan from Three. I feel lost.
Happy for all of you lucky people.
I posted more than a month ago that I changed from provider and that I had no more problems.
Just to let everybody know that this is still the case, no more problems :-)
In the beginning I had dropped calls, robotic voice quality and after changing from provider no more problems.
I had a support call with BASE (KPN GROUP) and 2 weeks ago the officially sent me an email saying that the do not support HD Voice quality
So go out and search a provider that is supporting the HD voice and all your problems will be gone...
For the dutch speaking guys, here is the email I received

Ik heb uw e-mail goed ontvangen.
HD voice quality wordt inderdaad momenteel nog niet ondersteund door het BASE-netwerk. Ik kan u helaas geen precieze datum geven wanneer dit geïplementeerd zou worden op ons netwerk.
Ik hoop u hiermee voldoende geïnformeerd te hebben.
Met vriendelijke groeten

I have the same robotic/digital sound problem, the sound is also quite laggy when this appears.In my experience the problem has gotten worse after the 6.1 update. I rarely experienced this when I first got the phone (on release date), but the problem is comming more ofthen now and sometimes I have to call back 2-3 times to make it disapear, sometimes it appears in the middle of a call too.
Carrier: Telia (Sweden) 3G/GPRS
The iPhone is a fairly expensive phone and I expect it to work and not to have these major faults regarding the call quality. I think that this is a hardware/firmware problem so please fix this!
Hello, did you try to investigate if it not by poor 3G signal and HD voice combination ?
It looks like t-mobile Czech Republic support HD voice see here:

- Za tímto účelem je spuštěna speciální hlasová linka 4004.
- Po zavolání na toto bezplatného číslo se zákazník dozví, zda má aktivní vysokou kvalitu zvukového přenosu HD Voice.
I have one friend on t-mobile and no problems at all and other with problems - either it is HW issue of iPhone or signal on t-mobile ??
Can someone help? I have tried everything with Verizon. Calls are awful. Apple tells me my 4th iPhone 5 is fine and that the carrier is having the problem. I am considering dumping Verizon and switching back to AT&T. As far as I'm concerned Verizon has breached our contract by never providing me with a usable line. Does anyone have a reliable experience switching to AT&T? I had them before and they were pretty awful too with dropped calls and lousy customer service. Any advice? I'm looking for real people btw, not paid brand advocates. Thanks!
Hey bud, if you choose to go to AT&T, don't expect anything less than the same issues you are having. I am with AT&T and have also had 3 iPhone 5 replacements and still a no go. I call apple and they say its AT&T's fault and then I call AT&T to hear the same thing about it being apples fault. I have had over 3 cases with AT&T and still wondering what they heck they are going to do about this issue. Apparently, they have an urgent team that handles issues from the people that won't put up with **** anymore and are demanding that the issue be fixed. So if you want to join AT&T, it's going to be a gamble. I'm about to just go with the Galaxy note 2 at this point :(.
Good luck and keep us posted to see what has been done :-)
Gabe, I'm going to stick it out with Verizon. Thanks so much for your thoughts. I had a feeling this was the case. Hate to go through all that and then find out it's the same problem. My guess is that some of these carriers have not yet caught up to Apple's HD voice technology in all areas. What a pain. Good luck. Hope we all get a fix and I hope that fix isn't the 5S because we'll be stuck with the 5.
As Scorpy75said, turning 3G off seems to "fix" the problem. I'll go where there is exelent 3G reseption and turn it on again to try replicate the issue with full service.
If I don't replay to this thread again it means that atleast my issue is due to bad 3G service.
