Will unlocked AT&T iPhone 4s work with another carrier simply by inserting their SIM card?

I went through the official AT&T unlocking process and want to know if my 4S will work with other carriers just by inserting a SIM?  Or is there some other thing I need to do?  Will it work in the U.S. or in other countries?  Thank you!

It should work with a GSM SIM card (like T-mobile in the US), as long as it as unlocked.  For international, make sure it is GSM.

  • Will the T-Mobile iPhone 6 work with AT&T LTE?

    Will the T-Mobile iPhone 6 work with AT&T LTE? This page seems to indicate it will: http://www.apple.com/iphone/LTE/ But I imagine the phone could be locked to T-Mobile.

    What about the contract free one?  It ships with a T-Mobile SIM and is unlocked (e.g. AT&T works with no issues on 4G for me), I'm just unable to get LTE.    I've noticed the "carrier" setting is missing from the Settings menus...however when I navigate to the About screen, it downloads the carrier specific updates, so based upon https://www.apple.com/iphone/LTE/ it should work, right?
    How do you get AT&T LTE on the contract-free/T-Mobile SKU?

  • Will the Verzion version iPhone 5 work with t-mobile?

    I have been wondering will the Verzion version iPhone 5 work with t-mobile?

    Just to clarify Meg's answer a bit, it will only work at 3G speeds in some cities. Outside of those few areas where T-Mobile has a 3G network that is compatible with the iPhone in the US, you won't even get that. You'll only get EDGE speeds in most of the country.

    Jailbroken devices are not support by this forum, or by Apple.  Apple reserves the right to refuse activation to any iOS device that is currently, or previously, been jailbroken.

  • My iphone 5 was stolen and I think they put their sim card into the phone can i trace it with their wi-fi credit?

    So couple days ago my iphone was stolen and i know about my iphone tracker because i've downloaded it and registered my device with it
    but obviously the theif will take my sim card out will I be able to track the iphone with their own sim card if they have internet credit on their sim card.

    If FindMyiPhone was turned on, you can trace it as you said, the thief cannot turn that off (iOS7). He can not use it. You can send a message and make your iPhone a dead brick, as soon as he iPhone connects to internet. Tell the police where you see it.

  • HT4053 Does the iPhone 5 lock you to a network after inserting a SIM card for the first time?

    If you buy an unlocked iPhone 5, when you insert your SIM card does it then lock the iPhone to that network, so that you then need an unlock code to switch networks.

    I have read other posts and have the answer. No need to respond to this question.

  • Will unlocked version of Verizon z30 works with indian networks?

    Hi all,
    I would like to buy Z30, unfortunately i am not able find this in Andhra pradesh. so i thought of get it from USA, even thers i couldn't find it, finally i am able to find some open stock in Verizon. they are providing unlocked version of Z30.
    now my doubts are,
    1. will it works in india or not?
    2. can i use indian networks with LTE?
    Please educate me guys.. i am eagerly waiting for Z30.
    I spoke to Verizon, customer, they are not sure with Indian networks, because the Verizon devices are explicitly designed for Verizon network, it wont work with other comapnies. and he tols one intresting thins that Verizon providing services in india also.

    It is possible because the price for an unlocked iPhone, and the price for a locked iPhone without a contract commitment is exactly the same. AT&T does not sell unlocked iPhones. If your friend bought it anywhere other than directly from Apple, it is a locked phone, not an unlocked phone. Contact the carrier it's locked to to find out what their conditions are for unlocking. Not all carriers offer unlocking (AT&T does: http://www.att.com/esupport/article.jsp?sid=KB414532&cv=820#fbid=35EsOeMYNgl )

  • Will unlocked T-mobile IPhone 6 work in HongKong or China?

    I'm thinking about buying a Iphone 6 plus T-mobile contract free version.
    I'm think about traveling back to China and HongKong later in the year, will the phone work there?

    Some purchasers have reported that the contract free T-Mobile version is unlocked. However, this comes with caveats. The warranty is only good in the US, and it would not work with LTE bands outside of the US.

  • Unlocked t mobile Iphone 5 work with verizon

    Hi, I recently bought an unlocked t mobile iPhone 5, but I have Verizon. Will the phone still work with verizon? And if so, what do I have to do to get it working?

    To be completely sure, here are the different models of iphone 5:
    Model number on the back cover:
    A1428: iPhone 5 (GSM model)
    A1429: iPhone 5 (GSM and CDMA model)
    A1442: iPhone 5 (CDMA model, China)
    (from Apple support website)
    So seeing as your iphone was a TMobile device, which would mean it has to be GSM capable, this phone is either an A1428 or A1429. If it is the A1429, that means it also will support CDMA, so you should be good to go on Verizon. If it is the A1428, not so much.
    So yeah, just take a look at the back of your phone, and you shall find the answers you seek.

  • Can iphone be use with another carrier other than at&t

    hi i would like to find whether can i used another carrier for iphone that i bought online from apple store?
    i travel frequently outside US and i have signed up some local country prepaid plan. can i switch to another carrier when i m in oversea?
    thanks
    .ps about to buy iphone

    I, too, am interested to know if I will be able to use a foreign SIM card when traveling overseas. I spend a significant amount of time outside the US and before buying an iPhone would need to make sure I could use the phone abroad with my other SIM card. The link above points to a FAQ that, alas, does not answer this question. It only mentions that the iPhone can be used abroad via roaming, which means paying AT&T astronomical data and call rates for international.

  • HT3939 Will my Canadian unlocked A1428 model iPhone 5 work with WIND MOBILE as it uses AWS 1700/2100 freq. same as T Mobile in USA?

    Which model should I ask in the Apple Store? A1428?

  • How can I get my old iPhone 5 (Verizon) unlocked for use with another carrier?

    I have an iPhone 5 that was purchased with a Verizon Wireless account.  It is more than two years old and I have since upgraded it to a newer iPhone.  I want to give this phone to a friend in Germany.  His service will provide a new sim, if the phone is unlocked.  How can I get it unlocked so that it is no longer limited only to Verizon Wireless?

        Good afternoon Weth!  That is completely correct. All 4G phones are already unlocked for global use. If you contact your international carrier and insert their sim card, it will be ready to activate on the international network. If you have any questions regarding the compatibility of the international network, please reach out to them directly. If you have any further questions, please let us know. Thanks so much and safe travels to you!

  • Can I use my sprint iPhone 4S with another carrier if it's unlocked

    Can I use my sprint iPhone 4S with another carrier if it's unlocked. Sprint will only unlock it if it's international. they will not unlock it if I want to use the iphone4s with another USA carrier.  Why? I have paid for the phone and don't have a contract.  I wanted to switch the SIM card and use tmobile or another provider because I am very dissatisfied with sprint service. Lots of drop calls and texting takes 15 to reach the other person.  It is horrible,,,, I hate sprint!,

    Sorry, what others here have said is wrong, wrong, wrong. There is nothing about the hardware of the iPhone 4S that would prevent a Sprint 4S from being used on T-Mobile, or any GSM carrier, international or domestic. Nothing. Zero. Zip. Zilch. Nada. Each and every 4S is 100% hardware capable of doing both GSM and CDMA out of the box. The only impediment is that Sprint would have to authorize an unlock for you. This is something they simply refuse to do. If anyone at Sprint has told you that they can't unlock a 4S for domestic use with another carrier, they have lied to your face. This, by the way, is something they're doing with everyone who asks the question - just Google search "Sprint unlock iPhone 4S", and you'll see dozens of internet threads where people talk about being lied to by Sprint about this issue. The good news is that Sprint signed an agreement with the FCC regarding letting off-contract customers unlock their phones. The agreement takes effect in mid-March, and Sprint is dragging its feet until then. Once that deadline passes, if Sprint still hasn't agreed to unlock your phone, then they're in violation of the agreement, and you can and should report them to the FCC. I sure plan to. Then I'm going to switch carriers, to one that doesn't lie to me and keep fraudulent liens on my property.
