Factory Unlocked AT&T iPhone 4, No Service

I followed all the steps to unlock my iPhone 4 and successfully unlocked my phone and restored it from backup.  However, when I tried putting in my co-workers sprint micro sim (for her iPhone 4s) to see if it worked, it keeps searching and eventually says "No Service".  She has service and is not under a 4G plan.  I've tried turning off my phone, resetting my network settings, replacing sim cards with the phone on and off, but still no luck.  I've never jailbroken my phone and my AT&T sim card still works on my phone.  Just doesn't work with other carriers.

That is because sprint is not a GSM carrier. They are CMDA only. They do roam on GSM networks that are outside of the US and that is what the micro sim is for in the US. If you need to have sprint on it then you need to have sprint provision the phone using the IMEI number.

  • Will factory unlocked/contract free iphone 4s work in trinidad and tobago?

    Bought a factory unlocked/ contract free iphone 4s from the apple store online directly, shipped to a family member and they're bringing it for me tomorrow. I've seen people complaining abt activation issues and stuff. I'm curious as to whether i'll encounter any problems. I shouldn't because my service provider is a registered apple partner (bmobile - they're still selling the iphone 4, haven't upgraded to 4s down here). Anything special i need to do to activate my iphone when i get it?

    US iPhone will not work with LTE/4G elsewhere. This is due to hardware
    in the US iPhone, and cannot be updated.

  • HT201328 how do i do a factory unlock to my iphone 4s?

    How can i perform a factory unlock on my iphone 4s?

    "Factory" unlock implies that the phone was purchased unlocked.  Your phone is carrier locked.  Only the carrier can unlock it.  Contact the carrier to whom the phone is locked and ask if the phone can be unlocked and what the requirements are.  Apple has nothing to do with this.

    Of course, those prices are also exactly what the current carrier locked, but unsubsidized contract free, iPhone 5's sell for now at AT&T and Verizon, so its hardly some great revelation that CNET stumbled upon.

    hello. my phone is factory unlocked.
    but my iphone support one network (Zong) only in pakistan. if i insert another network sim it support (Catch the signl and show the network name ) but cannot make a call or text neither incoming nor outgoing.
    plz guide me what should i do.
    ios 7.0.4

    There aren't any supported carriers in Pakistan. Apple hasn't released the iPhone there. The OP is using a grey-market iPhone and hence is pretty much on his/her own as regards getting this phone working with the carrier, unless that carrier can help.
    Regards.

    Unable to Activate Factory Unlocked AT&T iPhone 4s in SRI LANKA. Getting a 3G Signal But This Msg Pops Up

    Sorry to tell you this, but that phone is NOT unlocked. It's still locked to AT&T. ONLY AT&T can authorize unlocking it. Contact them and find out if you qualify.

    To be clear, you cannot get your phone "factory unlocked".
    In order to be factory unlocked, it is manufactured unlocked to any carriers at the factory.
    Phones that are locked cannot be "factory unlocked".
    They can be carrier unlocked (in some cases as Niel describes).

  • HT4623 how can i factory unlock my own iphone 4?

    people are offering an unlock service that's similar to a factory unlock from apple?? anyone heard of this?  and does apple offer a unlock service i'd rather pay them to do it, if they do? i just want my phone to work with tmobile.  .  .  . I HATE DROIDS!!!!

    Apple doesn't offer to do any unlocks, you have to do it through your cell provider.
    Assuming you have an AT&T phone: http://www.att.com/esupport/article.jsp?sid=KB414532&cv=820#fbid=3xy94pWGl76
    Keep in mind that unless you are in a limited number of areas you will only have EDGE speeds on your iPhone, no Visual Voice mail and some other lack of features.

  • HT1414 hello can you please advise me how to unlock my personal iphone from orange service provider as they are refusing to assist

    having been with orange for many years I was dissappointed with the merge into EE and purchased a seperate contract but when I asked orange to ask apple to unlock my old iphone 4 they refused and said I have to be a CURRENT ACCOUNT HOLDER FOR A PERIOD OF GREATER THAN 6 MONTH before they will unlock it !!!!

    Terms of conditions of a contract will trump anything that the user will be able to do on his own. I would reccomend you wait out the time period have the device unlocked and move on.
    My apologies
    Good luck Friend.

  • How can I request a Factory Unlock for my iPhone 5?

    I bought a used iPhone 5 that was locked to TMobile. I was told that I can request a free unlock from apple. I just wanted to know how I can go about doing this?

    Only the carrier to which an iphone is locked can unlock it.
    You would have to ask TMobile if they offer this service and if you qualify.
    Contact TMobile.  They are the only ones who can help you.

    There is no SIM card installed in the iPhone you are attempting to activate

    Is the SIM operating. Try taking it out and putting in again. Also try with a diffrent iPhone. Are you SURE your iPhone is unlocked? HOW did you unlock it? There is no such thing as a "factory unlock" on the iPhone.
