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
