Will a factory unlocked iPhone 4 still work with T-mobile US after being restored ?

My group messaging feature isn't available in my messages settings section.
I was told I needed to back-up and then re-store....how ever I use T-mobile US as my carrier.
Will it still work after the re-store ?

IF your iPhone was officially unlocked by the carrier it was originally locked to, then yes, it should remain unlocked forever at that point and a restore or upgrade will not alter the unlock.
However, if your phone was hacked to make it function as if it had been unlocked, then it will almost certainly relock to the original carrier when restored or upgraded (assuming it does not simply brick itself from the restore or upgrade, which is also a possability).

  • 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.

  • HT201274 Can a Sprint Iphone 5 work with T-mobile network? How can one unlock with the MSL code? Sprint is not abiding by the Unlocking Consumer Choice and Wireless Competition Act.  FCC will only enforce if we file more complains.

    T-Mobile is a GSM network whereas Sprint is a CDMA network. They are incompatible. Sprint is not obliged to unlock a phone that is still under contract. Their phones may not be capable of being unlocked.

  • Will a factory unlocked iphone 4s from the apple retail store come with a simcard.

    Will a factory unlocked iphone 4s from the apple retail store come with a simcard.Furthermore will my new phone need to be activated in store or can i do it myself

    No. You'll need to get a SIM from your carrier. Since you won't have a SIM, there will be no way to activate the iPhone at the store, so you'll have to do it yourself.
    Regards.

  • Will the at&t version of iphone 5 work with t-mobile?

    Will the at&t version of iphone 5 work with t-mobile? As I have a t-mobile prepaid plan and I really wanna buy it!!!
    And will t-mobile provide me with a nano-sim?

    Yes, but the officially unlocked iPhone is not available for sale in the US, at present. T-Mobile will have nano sim cards & they are advertising that iPhone 5 owners switch to their service.

  • Does the unlocked iphone 4 works with other networks besides at

    does unlocked iphone 4 works with other network besides at&t like verizon, sprint, and t-mobile ?

    An officially unlocked iphone 4 will work with other GSM networks.  The ONLY major GSM network in the U.S is T-Mobile ( who are being purchased by AT&T). Currently with T-Mobile you will not get 3G service  or visual voicemail with the iphone.

  • HT1937 Will a factory unlocked iPhone 5 A1429-GSM work in S Korea & USA?

    According to Apple, the model A1429 (GSM) is the one for South Korea- LTE bands 1 (2100 MHz), 3 (1800 MHz) and 5 (850 MHz).
    When I return to the US in 2014 will I be able to use it on Verizon and sprint's network? I noticed that the LTE band 1, 3 and 5 are also supported by those two US carriers.  However, those two carriers use a different platform/technology (CDMA).
    I am positive that the A1429 GSM will use a nano sim card.  What about the CDMA? Please clarify.
    I am contract free as of yesterday and able to go with either of the carriers and be able to factory unlock it before my departure in January 2013. However, the hardware must work in Korea and in the US.
    Another option that I am considering is a factory unlocked iPhone 4S, but I cant find a 32GB.  I am very reluctant with this option as I am afraid that when I return to the US (Jan 2014) things will drastically change and I wont be able to enjoy the new advancements in the mobile tech world because I have a hardware that wont handle them.
    Thank you. 

    Apple does sell the A1429 GSM in Europe

    Hi Liju,
    There is nothing to worry at all. a FU iPhone works with any carrier including Airtel and Vodafone in any city of India. based on my experience that has been explained earlier in this thread, it is better to use a New SIM.
    I prepared the micro sim on my own by cutting the sim with a cutter. It is quite a simple process. Just browse through web, you get lot of info on that. As far as activation process is concerned, it is **** simple. Insert micro SIM into phone. Connect it to iTunes and register it. That's it. Your phone gets activated within few seconds.

    You heard wrong.  IF the device is officially unlocked by Apple, it will not be relocked.  IF it was hacked to be unlocked, upgrading iOS WILL relock the device to the original carrier.

  • Would my UK unlocked iPhone 3GS work on t-mobile US 3G network?

    I have a unlocked iPhone 3GS bought from the UK last year. I know US iPhones dont work on t-mobile's 3G network due to network incompatibility. However, do UK iPhones work on t-mobile's 3G network?

    The same incompatibility exists in all GSM iPhones. They can use the US T-Mobile network, but only using EDGE since T-Mobile's 3G service uses a frequency not supported in the iPhone.

  • Will a factory unlocked iPhone 4S, bought in Singapore, work in India?

    Hey guys.. I just love the iPhone 4S and want to buy it as a mark of my respect for the late Steve jobs. But sadly it isn't available in India. So I asked my friend to pick up an unlocked iPhone 4S from Singapore. My concern is, will it work with the local GSM Sim card in India?
    Thx fr your time!

    In my personal opinion the 4s is not much different than the 4! I am using both.
    The major difference is the camera but the rest including the faster processor still feels the same!!
    Anytime now the jailbreak is gonna come out and u will most likely be able to use Siri on the 4 too!!
    But no doubt the 4s is a sweet phone!!
    I got the 64gb AT&amp;T contract free and it worked perfectly fine in India since the day one!!
    Siri works smoothly and is quite helpful... Thou its kinda difficult for her to understand Indian names..
    Apart from that no settings were changed.. It worked straight out of the box!
    If u can't live without it then buy the 4s but if ur not so much of a ifreak then the original 4 is not a bad bet either!!
    Hope I could help!!

  • Will an unlocked iPhone 4S work with both CDMA and GSM SIM cards?

    I was using the iPhone 4S with a GSM sim card all these years here in India and would like to switch to a CDMA carrier.
    Does the phone work with both SIM cards? Or is there a separate model which works with CDMA?
    Appreciate all replies.
    Thank You!

    "Can I use my iPhone outside my home country?
    Yes. iPhone is enabled to work on carrier networks using GSM around the world. Because the iPhone sold by the Apple Online Store is commitment-free, you can purchase a SIM or micro-SIM card and service from a local carrier at your destination. "
