    Not sure why we want to restore it to the earlier iOS version since the phone is at factory unlocked stage. One would think that they would let Itunes does its job as long as it's in working status.
    Recall that I mention it is a good possibility it could be a hardware issue, like the surrounding antenna.

    the OP has said he has restored multiple times but it didnt fix the issue, but it is under the assumption that he restored back to 5.1.1.

    The reasons I suggested to do a restore to a different iOS is:

    A. Prevent you guys from having a useless iphone that cant make calls
    B. Save you the money to have it taken to a repair shop that "may" fix the issue, but not guarantee neither

    I do understand the meaning of it being unlocked, and its not "factory unlocked", its an "IMEI unlocked".

    However, I am merely suggesting to different venues to see if there "may" be an iOS issue.

    By all means, if you feel you have done enough, take it to a repair shop.

    bud I think its very likely to be a hardware issue, I dont know exactly what but my guess is the antenna because even with a new microsim, you are unable to obtain a signal

SIM this is normal and has 1,8 Volt, as iphone 4 needs
    i have a A1 SIM, the card if i put the card in iphone will be clean recognized in the Settings i can see the carrier A1 Telecom 0.12 no service too but this card is deactivated. if i put the eplus SIm in settings i see: Carrier 0.13 an no eplus. i've purchased a new one SIM from eplus if it not helps i will cry ... i do not understand that

    your problem seems awfully familar to the orig iphone4's back in 2010. if i remember correctly there were several folks complaining of the same issue. turns out, these batchs of phones had a problem with the sim card shorting out with the internals of the phone via sim tray. they resolved the problem by placing a thin layer of tape along the internal edges of the sim tray (same side as the gold pins of the sim card which will contact the tray). this will prevent the internal parts of the sim tray bay from shorting out to the sim card.

    just give it a try

    Default Same Problem
    BUMP in case someone found a solution to this?

    My Iphone 4 iOs 6.0.1 base band 04.12.02 AT&T IMEI unlocked doesn't recognizes local Mexico's Telcel provider, just " No Service" with New SIM, I did iTunes and nothing, installed redsn0w tethered jailbreak using 6.0 firmware, installed SAM ( Subscriber Artificial Module ), nothing..

    I have notice thou, that when I could get it to receive or make calls there was a small pointer triangule icon next to the battery tray , one this would apear the network will fall and lose connection to subscriber.

    I saw here on the internet maybe downgrading to 5.1.1 could work but don't know if I have the SHSH bloobs files ?!

    Any help is very much appreciated, i dont want this as an expensive Ipod..

    OK, to break it down. I have done everything that the internet has suggested.
    I have the iPhone 4 6.1.3 factory unlocked for all sims.
    I called AT&T to verify that the phone is not blacklisted. The rep told me the phone has not been reported lost or stolen and DOES show that the device IS factory unlocked and even gave me the date for which it was unlocked (which matched my records).
    Iphone picks up AT&T signal and makes calls. I tried two Tmobile sims and neither work. Yet both work in my other factory unlocked iPhone 4.

    Has ANYONE with this issue actually found a resolution?

    A lot of people are saying it's a hardware issue, but I can't see how it is. If the phone works with some sims and not others, then the phone is mechanically sound. It's a software issue which may come from new updates. T-Mobile is now selling the iphone 5 leading me to believe that there is an issue with the software that isn't compatible with or disrupting service to older iphones. We either need to wait for an update or pray that the dev team gods can grace us once again with their intellect.

    I'm assuming you've received the pop-up "Congratulations, your iPhone has been unlocked!" message in iTunes, yeah?

    I'd still try de-activating the iPhone via redsn0w (Extras -> Even More -> Deactivate) and then plugging it into iTunes with your desired SIM, see if that does it.

    I have received the Congratulations message. I haven't tried to deactivate with Redsn0w though. I'll try that tonight and see how it goes. I'll let you all know what my progress is. I'm sure everyone would like to have a solution for this.

    ok, i tried to deactivate through redsn0w and got this message in itunes "We're sorry, we are unable to continue with your activation at this time." How do I activate it again?
