Iphone carrier locked

hi there? i wanna ask you guys? how can i find my iphone 4 carrier locked. my iphone model MC603B/A. thank

Have you always used this iPhone or did you purchase it second hand?
Because if you have always used it then the sim has been working in the iPhone is most likely of the carrier it is locked to. If you purchased it second hand then ask the original owner what carrier they used with the iPhone.
once you know who the carrier is then you need to contact them and ask if they can unlock the iPhone.

  • I would like to know which carrier my iPhone is locked to

    Hello Apple support,
    After many attemps to contact you I landed here, so here is my question.
    I recently bought an iPhone 4 over the internet which was locked and not yet activated.
    Therefor I need to find out which carrier my iPhone is locked to so I can finally start using this thing, I will not provide my IMEI number in public for security reasons.
    So is it possible to check my Carrier lock status by my IMEI / serial number? Because I think it is AT&T yet I am not sure, and I can't check it because I live in Belgium where I cannot get a hold of an AT&T sim card. The owner told me it was a dutch phone so it had to be locked with T-Mobile yet they don't seem to recognize the IMEI. The model number is MC318LL LL is coded for America as I seem to have heard.
    Please do help me because I have made MANY attempts finding this out!
    Many thanks in advance,
    Jan

    This is a user to user help forum only.
    This cannot be determined by users with the info provided, and I'm not sure if Apple would give you this info over the phone if you called AppleCare in the U.S. - for security and privacy reasons.
    You need to get this info from the seller. If the seller is unable to give you this info or the correct info, return it to the seller for payment credit and purchase an iPhone in your country from an official retailer and you will have less problems or no problems including not having to hack the iPhone to unlock it which removes all the built-in security making it insecure as with an Android phone.

  • HELP! I want to know whether my hand-me-down iPhone 4 is SIM/carrier-locked or not. I was given an iPhone 4 which I think was purchased outside the Philippines.

    I was given an iPhone 4 which I believed was purchased outside the Philippines. The previous owner had it jailbroken but something went wrong so it was stuck on DFU mode. So when it was given to me, I had it restored and updated via iTunes to iOS 5.1. I bought a micro-sim and inserted it on the sim tray. iTunes was able to detect the SIM card number and there was NO MESSAGE like the sim card is not supported whatsoever which can be usually seen in unsupported simcard. I thought everything went smoothly. But when I tried to set-up the phone, the SLIDE TO UNLOCK button is unresponsive. It doesn't work so I was stuck there and my iPhone cannot be accessed because of that. What shall I do? I have tried doing the hard reset several times, it still didn't work. I have tried restoring my iPhone three times but the slide to unlock is still unresponsive. I think the iPhone was able to detect my carrier simcard since it shows on the top corner the name of my carrier, mobile signal and 3g network. Now I am wondering as to why the slide to unlock button is unresponsive? Was it because of my iPhone LCD or was it because the iPhone is locked? Please help.

    according to some blogs, if the sim card you are using is unsupported, iTunes will show you a message that the sim card you are using is unsupported. But when i opened itunes, I didn't see that message. Instead, it was able to detect my sim card number. So I guess, the simcard is supported. It isn't the original sim, though. Then the phone was able to detect the mobile carrier, mobile and 3g signals. So iam wondering whether my phone is locked or was it a hardware problem?

  • Please help me know to which carrier my iPhone is locked to! All possible details provided.

    My 16GB Black iPhone Model number: MC318LL; IMEI: 012657005583409 Now I want to know to which CARRIER my iPhone is locked! As per the model number I found my iPhone was purchased in Singapore. Please help me out. Thank you in advance.

    There is no way to tell based on the information you provided.
    According to this page: http://support.apple.com/kb/ht1937
    ALL iPhones (the 4 at least) sold through authorized channels in Singapore are unlocked. If you got it on the gray market, as opposed to from one of the three authorized carriers or directly from Apple, and you're getting an "unsupported SIM" message, then you got taken for a ride.

  • I had my iphone 4 locked to vodafone uk carrier. I connected the phone to itunes on my pc and tried to update the version to ios 6 through itunes. But it has been locked and asks for sim of previous carrier. how can i return to previous state?

    You cannot return to previous state. The update re-locked the iPhone
    to the original carrier. You must contact the original carrier to see if
    they offer unlocking and if you qualify.
    What does it say when you look at Settings=>General=>Carrier?
    Be advised that if your iPhone had previously been hacked/modified/
    jailbroken to work with other than original carrier, it may be impossible
    for the original carrier to unlock it properly.

  • I have iphone 4s from japan which is a carrier locked (kddi ) it has ios 5.1.1 and now i want to upgrade to ios 6.Can i do the software update or it will cause any harm???

    i have iphone 4s from japan which is a carrier locked (kddi ) it has ios 5.1.1 and now i want to upgrade to ios 6.Can i do the software update or it will cause any harm???

    If you have a Japanese iPhone and are using it with any carrier other than Softbank or AU, then it was hacked, since as the others have said neither of those carriers unlock iPhones. Therefore if you upgrade iOS or restore your iPhone, it will lock back to the original carrier and be unusuable with your current cell provider.
    We cannot help you with jailbroken iPhones. You'll have to look elsewhere for further assistance.

  • HT4993 Can i get factory unlock my iPhone 4S at sprint carrier locked

    I want my iPhone factory unlock at Sprint Carrier locked, to use any gsm carrier sim worldwide.. Is there any way to officialy unlock it

    What part of:
    "No Sprint model iPhone can be officially unlocked."
    Do you not understand?
    There is nothing more I can add to this thread. If you want an officially unlocked iPhone, you have the wrong model. Sell it. Don't want to do that? You're on your own
    Good luck.

  • My iphone 5 is carrier locked to verizon

    So I bought a iPhone 5 from my friend, and he told me that the verizon iphone 5 is unlocked so I could use it on any network.
    However, when i checked with Apple, they told me that the verizon iphone 5 i bought is carrier locked to verizon.
    So I called and asked them to unlock it from the network, and I was immediately refused multiple times.
    I am really stuck on what I can do at this point... could anyone in the verizon community care to help me out?
    It would save me tons of time and work. Thank you in advance.

    Have you tried using a SIM from a different carrier? I know that Apple says it is carrier locked, but there are several instances on these forums where people have "claimed" to have been able to use a different carrier with a Verizon iPhone. I assume you have service with a different provider. Just get a SIM card from them and try it in your phone.
    This would not be able to work the other way around, though. Verizon iPhones have both CDMA and GSM radios, where GSM carrier iPhones do not have the CDMA radio.
    Hopefully this will work for you, however if it does not, you will have to bring it up with your "friend". It was his mistake. You could sell the phone on a site such as Swappa.com.

  • Get a new non carrier locked iPhone?

    Well I canceled my sprint contract and I'm left with a carrier locked iPhone for sprint, well since I bought apple care + I have insurance on phone. My iPhone 4s has battery issues and if I went to apple and they gave me a new iPhone would that new one be carrier free meaning I could take it to AT&T with me? I think that would be the case right?

    Well all the iPhones are the same when new when you activate it to a carrier, the carrier then locks it to its company, so if it's unactivated and they give me unactivated new phone then it's not locked to anything, this should work because I had learned that all the iPhone 4s have same internals because apple designed to work both ways.?

  • HT1937 i have iphone 5 carrier locked to sprint so how can it be factory unlocked ?

    i have iphone 5 carrier locked to sprint so how can it be factory unlocked ?
    what is a good way to unlock it as i am in UAE now

    Don't waste your time, as I've already stated, Sprint WILL NOT autrhorize the unlocking of your sim slot.
    You wasted your money. Return the phone for a refund, if you can, otherwise, sell it to someone that can use it on Sprint's network in the US.

  • Got an Iphone 3gs from a friend, unable to use due to previous carrier lock, talked to carrier and they say they have unlocked it, but the Iphone is still locked, what to do?

    I got a used Iphone3gs from a friend.
    I do not use the same carrier as the one he purchased the Iphone from.
    I had him call the Operator and they said they have unlocked it in their system.
    However the iPhone remains locked and the carrier (uder settings>about) is still listed as the original Carrier.
    the phone as NOT been hacked.
    I do not have a "Carrier" option listed in the main settings menu
    and therefore have no way to change it manually
    please help

    This the procedure

    I'm going to make some guesses here. You bought your phone second hand. In other words, not from Apple and not from your carrier. What you got is a hacked phone that was originally carrier locked, most likely to AT&T in the US. You are NOT in the US. (If I get any of this wrong, please tell me).
    What has happened is when you updated the software, it was re-locked to the original carrier.  ONLY the carrier can authorize an unlock. If it is locked to AT&T, you're out of luck as they WILL NOT unlock an iPhone for any reason.
    If it's locked to another carrier, you will have to find out what carrier that is (you can NOT tell by looking at the model number) and find out if they unlock iPhones. If you can't find out, or if they do not, then your only real option is to sell the phone and purchase one from a LEGITIMATE source.

  • Do bought from Apple Store iPhones get locked to first sim carrier?

    I have bought many iPhones for myself and my family over the years and always on contract, UNTIL the iPhone 5.  When it came out, I decided to avoid all the unlocking mess and contract handset subsidy thing and buy an unlocked (or so I thought) iPhone 5 from Apple.  Now, someone told me the other day, that the 'unlocked' handset becomes locked to the carrier of the first sim that is inserted.
    Surely this can't be true, is it?

    02 support told me today they had seen iPhones become locked to thier network even though they were bought SIM free.
    Either way it's a complete Nightmare sorting out what's going on here!
    Seb
    Apple support have told me today that their unlocked handsets are locked to the carrier of the first sim card inserted. BUT, they also said that doing a forced restore in iTunes with a different carrier's sim will then lock it to that carrier.
    However, I was also told that certain sim cards can totally lock handsets.  This I find disturbing.  Take the scenario that you want to check to see if a handset is unlocked.  Standard procedure is to try a sim from another carrier. You'd get a bit of a suprise when you put your original sim back into your phone to find that it no longer works as it's been locked to another carrier!
