Why has my unlocked iphone 3gs got no signal

just bought a iphone 3gs and its suppose to be unlocked but i have tried every sim card and it still says no service

Where did you buy this iPhone? Sounds like it is looked to a wireless
carrier and you have not yet inserted the correct sim.
What does it say when you look at Settings=>General=>Carrier?
Does the app Cydia appear on the iPhone?

    ALL U.S. iphones are carrier locked to AT&T, no exceptions. They cannot be activated with any other carrier in any other country.

  • Will Apple cover my factory unlocked iphone 3GS anywhere in the world?

    Hello,
    I'm planning on buying a factory unlocked iphone 3GS directly from the Apple Store in Hong Kong.
    Will Apple cover my iphone with the warranty worldwide or only in Hong Kong?
    Thank you.

    What I meant to say is that technically, hardware-wise, almost all iphones 3GS are the same (I believe the models in mainland China don't have GPS?).
    It's no WiFi in China. GPS used to be illegal in Egypt, but they changed the law recently.
    Correct me if I'm wrong but I suppose that the carrier lock is a software lock, which can be removed (we've all heard about it), but gets reversed once you update to a new OS version.
    Carriers can ask Apple to unlock particular phones. The next time the iPhone is restored via iTunes, new firmware will be downloaded from Apple and will display a message saying it has been unlocked. It will stay unlocked if updated. Unofficial unlocks (which can not be done on current iPhones) will re-lock if the iPhone is updated.
    I know it is the way it is, but I believe most of you would agree that if you buy a telephone, you shouldn't be forced to go with one carrier or another. That is why when I pay for an unlocked phone, I pay much more, go get the freedom (without hacks) to choose the carrier I want (where in contrast I pay much less for calls and internet than with the exclusive iphone carrier).
    It would be much easier for Apple if all iPhones were unlocked, and the same in all countries, but the carriers make a fortune from their exorbitant roaming charges, so where the country's laws allow, insist that Apple not make any unlocked iPhones available in their countries.
    By the way, MMS is not something most people use. There are some statistics on the internet about the ratio of SMS to MMS and it was something like 10 to 1.
    All the 3G and 3GS iPhones are capable of MMS, but the carriers have to support it.

  • I hve unlocked iphone and got walmart family mobile. I was issued a phone number initially with phone and then I had them change it. Now when I send texts caller id people see is the original phone number, and when I call it is the new number.

    I have unlocked iphone and got walmart family mobile. I was issued a phone number initially then asked for a different one. Now when I send text messages, they show up the original number, but when I make phone calls, the id shows up the new number, I can recieve text messages to both numbers. If you try to call the first number it says it is not a working number. On my phone, if I go under "about" it says "my phone number" and it says the second number, under settings, and messaging, it says that I send and recieve messages from the original one. T-mobile, has no idea why this is happening and has tried everything to fix it

    This is for iMessages only, not for text messages as in SMS/MMS.
    Settings > Messages > Send & Receive > Apple ID.
    Select your Apple ID and at the menu window that appears, select Sign Out.
    Turn iMessage off at Settings > Messages > iMessage.
    Then follow these instructions.
    You can remove an iPhone from your support profile by following these steps.
    Step 1: Click on this link to open the login window of your support profile.
    Step 2: Log into the website using your Apple ID – same as your iTunes login.
    Step 3: Click on the button ‘Edit products’ and select the iPhone that you want to remove from the list.
    Step 4: Click on the arrow behind the product, and then click on the button ‘Unregister’ to delete the iPhone from your support profile.
    After you unregister your iPhone, on your iPhone go to Settings > Messages > iMessage and turn iMessage on.
    Go to Settings < Messages > Send & Receive > Apple ID. Sign back in with your Apple ID.
    This should re-register your iPhone with your Apple ID with iMessage with the new phone number only.

  • How to activate factory unlocked iphone 3gs with os 4.0

    i have bought a factory unlocked iphone 3gs loaded with latest os 4.0 in usa for $850 , but i am unable to activate it over itunes.
    I want to activate it without at&t sim as its factory unloacked.
    Can anybody give me the process or any reference links on how to activate it.
    Thanks in advance,
    Pavan Raj.

    If the iPhone had the 4.0 Beta loaded on it, the iPhone needs to be registered with a developer for the iPhone to even function. If it's not registered and the beta is installed then it is a brick. Regardless of if it is registered or not, as Tamara said the iPhone 4.0 Beta has no support. The Beta is a beta and is for developers who are developing apps. That way they can release apps as soon as the OS 4.0 is released sometime this summer. You should get an error message saying something along the lines of this phone is not registered with a developer, if the iPhone is not registered.

    If it is unlocked by the carrier then you just need to plug it into iTunes with a SIM card from a compatible carrier. If you get a message saying that the SIM is not from an authorized carrier, well then the iPhone is not unlocked, sorry.
    If the iPhone is not unlocked you are really out of luck. While there are ways to hack an iPhone to unlock it, there are no methods for the 4.0 Beta to unlock the iPhone, and even if there is a way to hack it to unlock the iPhone 3GS on the 4.0 OS, it won't come for a long time.

  • Apple unlocked iPhone 3gs on T-mobile / Rogers Prepaid

    I would like to buy the unlocked iPhone 3gs. I travel and use Rogers prepaid in Canada and T-mobile prepaid in the US. I only use voice and email, so will a straight SIM swap work ?

    Money is what i am concerned about.  I'm hesitant to purchase an iphone with at&t's costly plans for 2 years, that is why I'm considering to buy an ipod touch in addition to purchasing a prepaid phone.  But I am unsure if it is worth it or not.

  • Okay i just recently asked a question.about my factory unlocked iphone 3gs asking how to activate it but..

    i probably shouldnt say this but,okay i just recently asked a question.about my factory unlocked iphone 3gs asking how to activate it. so i got too excited of aving it and couldnt wait for my tmobile sim card to come  one more day. so i "hactivated" it (i know this voids all warrenty) and i jailbroke it just so i could use it as an ipod.it worked and i was syched.
    BUTTT.... it asked me if i wanted to update the software to 5.1 and i was like " oh yes id love to" and it started downloading it and it was inrecovery mode the whole time .
    when the download finished. i hit restore so i can put the software on the phone but the itunes had an error and the phone went glitchy and it does a rebooting loop. it shows the apple symbol with the slash through it for about 5 seconds and shuts off for a little bit (about another 5 seconds) and it starts up  then loops the process. ive managed to turn the phone off but if i start  it up it loops...what should i do? any help :/
    Also it does not show up in my itunes because it is turning off to fast to detect.

    Discussion of hacked phones is prohibited on these forums.  Sorry, you'll need to go elsewhere to get support for a j'broke iPhone.

  • HT1766 i have an unlocked iphone 3gs and need an upgrade how do i upgrade without losing my unlocked status?

    I have an unlocked iphone 3gs how do i upgrade without losing my unlocked status without having to pay to unlock it again.

    Updating and restoring does not lock, but if you have a jailbreak (not AppleSoftware) and you return to Apple Software then it will lock. After all Apple has to keep to the law. It is even possible, that the jailbreak software makes it impossible to install Apple Software again and your iPhone will be inoperable after you try the update.
    So If you officially unlocked you are  fine and if you had a jailbreak, there is nothing an Apple forum can do for you.

  • How do I get a factory unlocked iPhone 3GS out of (connect to iTunes) mode?

    How do I get a factory unlocked iPhone 3GS out of recovery (connect to itunes) mode? 
    Once the iPhone 3GS is in DFU mode and plugged into iTunes, the restore and update process begins. The restores process are as followed:
    Extracting software > Preparing iPhone for restore (blank screen) > Preparing iPhone software for restore > Restoring iPhone software > Verifying iPhone restore > Restoring iPhone firmware > The iPhone cannot be restored. An unknown error occurred (1).
    I clicked on the more information tab and was taken to a website with some troubleshooting. I did what they suggested (based on the error #) and still no luck. I’ve tried to restore and update about 10 times now but the same message keeps coming up at the end. What should I do now?
    P.S: I have the latest version of iTunes (11), my windows is up to date etc ...

  • My uncle sent me a factory unlocked iphone 3gs from US and sent it to me to India. but when i inserted a sim ,it said that my simcard is not combatible. is there any chance to solve this problem. the phone was bought from a apple reseller.

    it worked in US with a sprint sim card. i am very sure that it wasnt jailbroken. then how this happened. plz explain me what i should do

    A: There is no such thing as an unlocked iPhone 3Gs in the United States. ALL iPhone 3Gs's sold in the US are locked to AT&T. AT&T will NOT unlock iPhones, therefore it is not legitimately unlocked.
    B: Sprint is a CDMA network as others have mentioned. They do NOT use SIM cards. The iPhone 3Gs will NEVER work on Sprint. Ever. It's not physically possible.
    Either your Uncle misunderstood or he was mislead. Send it back and tell him to get his money back. Buy an iPhone in India from a supported carrier.

  • Is unlocked iphone 3gs a good choice for use in the UK with PAYG?

    I've never had a smartphone. I'm thinking of buying the unlocked iphone 3gs to use when I'm in the UK 2-3 (months a year). I would be using a pay as you go sim with a little data use included. All I need is the ability to call, text, email, blog, and check facebook. Would this phone be a good choice for me. I'm hearing that there are some problems with battery life on the iphone 4. Does the 3gs have those issues? Also what does the 's' stand for?
    Any helpful info apppreciated.
    Robertson

    This is the deal I'm looking at. As you can see it comes with the upated OS. $375. Is already a bit more than I would normally spend on a phone.

    You didn't buy an 'unlocked' iPhone 3GS - you bought a 'hacked' one.
    Updating to iOS 5 removed the hack and the unofficial unlock.
    All you can do is try to find out which network the phone is locked to and ask them if they can unlock it properly.
    Otherwise, sell it or throw it away and buy an officially unlocked phone from an official source.
