Щиро дякую!

I have followed that brilliant instruction and now I have iPhone 4S instead of iPod Touch 4S!!!

The solution of my "SIM failure" and "dropping network" problems is on the page:

P.S. It is really nice device... . I mean iPhone 4S. )

I've got the same issue in Melbourne, displays full rescieption from optus...however, unable to call... this only started last night and seems getting worse!

     Hello! I have the same problem!

Black Iphone 4S 32gb IOS 5.0.1 (9А406)

Model: MD242F

modem: 1.0.14

     Apple, I dreamed of this phone. I saved money 2 months to buy it. I live in Russia and 730 euro to me is a real big money. But i buy it!!!! and now... What i have?

     My friends takes offense at me, as can't phone to me. I can't call... To have to conjure with a tambourine with this iPod, to call someone. I tried all variants that found in the Internet - doesn't help.

     Any official statement. It disappoints:(

     Please, solve this problem faster.

No need to tell Apple about this. Some fool called me "whinner" because I complaint even when there is no official word from Apple to resolve this and other issiues with 4s and to make things even more interesting they deleted my post!

Same problem, I live in Kazakhstan and there is no official sellers, bought my phone in Abu dhabi airport. God i regret that I spent money on it. Tired of sleepless nights trying to find something to make it work. I hate  I phones!!!!!!!!!!!

I've had my new factory-unlocked 4S for 2 months now (on Orange) and I often get "Call Failed" when trying to make a call - sometimes during a call too as the call is dropped. This happens even when the signal strength seems good. Also failures sending SMS messages. The problem seems worse when I am at home. When I am at home I happen to be connected to my home WiFi, so perhaps WiFi is contributing to the problem. Turning off WiFi sometimes helps but not always.

I also have the problem where the person on the other end can't hear me. If I switch to Speaker phone then they can hear me. There is nothing wrong with my microphone. This happens mostly with one particular caller who also has an iPhone. Perhaps the problem only occurs when calling iPhone to iPhone? (One user on a forum mentioned the problem occurs if the number called includes the country code but not if dialing 0 plus the area code (eg. dialing +12-34-... versus 034-....) I have not confirmed this.)

I upgraded from iOSv5.0.1 (9A405) to 9A406 because I also got the "No Carrier" problem at least once, but this did not solve the "Call Failed" problem.

Usefull link, obviously the guy is well educated with apple eq.

Trust me ppl I master the issues, reading days and nights, changing all kinds of combination, dying to solve the problem and I'm still sceptic about it, I'll see in the morning.

Anyways the combination that worked for me for the first time and I got my 4s 2 weeks ago, not a brand new but used and used normaly with another carrier micro sim.

Before everything I put the tape really slim one on the part of the card holder where micro sim chip is touching the metal construction of the microsim card holder. I saw that from one of the guys experincing same issues on apple support site.

iPhone 4S 32 gb black

firmware 9A406 >> downloaded and updateded from iTunes

Settings > General > Date and Time > Set automaticly is OFF ( u will notice here and also when u press clock and this is for new not back up iPhones so there's no restore mode, a fresh copy and begining of using the phone, so when u press clock u will see that u have time in Cupertino, u will also see that maybe not maybe yes when u go to date and time that u have time zone and if u have Cupertion or some other city then yours then u will not be able to have outgoing calls).

Then u have caller ID, waiting and forwarding, caller ID should be turned on, those other 2 off and u have to check also if u can see your own number showing in Settings > Phone)

Settings  > General > Network > Celular Data ( this option is free of choice) I personaly turned it off, cause I don't have any internet plan with my carrier only calls and sms so I swtiched it off. I don't think that this can affect on connection and signal. It's simply a bug in a software. You can also check that when u go to Settings >> General >> ABout >> Diagnostic & Usage data >> here u gonna see alot of shiite happening

Settings >> Message >> iMessage off ( this is not necessary specialy for people from US, this option is desired to be turned off in Europe)

Settings >> WiFi >> turn off the ask to join networks ( this is for the ppl who have problem with wifi)

Settings >> Carrier >> Automatic ON ( if u put manual and then pick up the carrier which is yours, the software again will be mixing up with other carriers specialy if he's using some data to overcome to low signal or bad network, the phone will actualy use info from another carrier and continue to work on his own from the sim card.)

I think this is about it, the combination that works for me as it seems. Like I sad I'll update again and tell u about the sim card failure and no device and bla bla in the morning when I go to sleep so as iPhone(maybe he's having nightmares )))

I don't want to be subjective so I'll wait for tomorow and when I start to change my location. Im at home and my iPhone is working fine and Im saying this again for the first time without buging outgoing calls and messeges. Time and date solved my problem for now.

Good luck to you all !!!
Cheers

Fail again, no solution for this ******!

I went to the Apple Store tonight for the "call failed" issue. In my case, it would ALWAYS work if I disabled Cellular Data. I would also often have issues receiving calls. The problems were totally random and irritating. The guy at the store checked my serial number and ran some diags and said that based on those 2 things, my modem firmware was causing a known issue. He applied the fix. We'll know soon.

Keep on dreaming! Instead, think different (brand). So dissapointed by apple.

Just adding that I have the same problem with my iPhone 4S (for Apple statistics, in case they care). No failed calls (yet) but failed SMS messages and intermittent 'SIM failure' messages. Reboot helps so far - for a few days. Also on iOS 5.01 by the way.

Come on Apple... get your act together please.

Hi veryone,

I am on my third iphone 4s on o2 UK and still having dropped calls 4 months down the line. I am paying £41 a month for a phone that can't make and recieve calls. I'm not sure what my next step it except give my phone back and swap for one that might actually work. I am so fustrated and the apple shop just keep replacing the phone no other solution. O2 are saying its not their fault.

Why do we have to put up for this when we are paying so much money????

Are you restoring from the same backup every time? If so, try not doing.

Take a look at my post here https://discussions.apple.com/message/17060400#17060400

Same here in holland, iphone 4s with tmobile. workaround is to make a call and put it on speaker, once you hear it ring  then put it off the speaker and the call will work nicely.

Never had this issue on my iPhone4/iphone 3G or iPhone1
