If you carefully follow all of the instructions in this tip and none of them restore WiFi then your radio chip has failed and you need to get the phone replaced by Apple.

  • IPhone 5 unlocked GSM

    Hello, I need some help from anyone in the US please!
    So, I live in Portugal where the compatible bands are: GSM 900/1800 3G 900/2100MHz LTE 800/2600MHz
    And I'm considering purchasing an iPhone 5 from USA on eBay because it's much cheaper, it says in the product description that it is an Apple iPhone 5 - Certified Pre-Owned Factory Unlocked GSM Smartphone
    Does that mean it will work in all the GSM bands, including the ones in Portugal? Will it be able to use 3G or 4G?
    Please help!

    Yes, it is.

I tried its not working can anyone pls help me i judt wanns be able to use my uphone to tje fullest of its abilitys!!!

    iOS 4.2.1 is the final version of iOS that an iPhone 3G will run, so you will not be able to use any apps that require iOS 4.3 or later. There is no way to get any later version of iOS onto your iPhone without serious hacking, something we cannot discuss here.
    You do not get the option to update iOS directly from an iPhone until you have iOS 5 or later.

  • Unlock GSM for international calling

    I am considering Iphone purchase but I need a phone that has unlocked GSM that can be used with various SIM cards. I notice that Iphone supports 850/900/1800/900mHz which is good, but I cannot find any info concerning unlocking GSM to allow phone to be used internationally with foreign SIM cards. Does anyone know if I can purchase an Iphone with unlocked GSM that will work with foreign SIM cards? Thanks in advance for your responses.

    Indeed it will. And that's fine as long as you are on somebody's expense account. Alas, if you are a mere financial mortal schlub, you'd be better off doing what I do and carry a cheap unlocked GSM phone for use abroad, and either use a European Roaming Sim Card (like United Mobile) or buy a local sim card if you will be in-country for a little while.
    Is all this a pain? You bet. That's why we're all begging for unlocked iPhones!

  • Thanks this was very useful.. I have a brand new iphone 4s unlocked version from singapore and I am having the same problem constant network fluctuations, no service, call failed, invalid sim, sim failure, bars fluctuating from 5 - 3 - 2 - 1, no signal/ba

    I have a brand new iphone 4s unlocked version from singapore and I am experiencing constant network fluctuations on my iphone , no service, call failed, invalid sim, sim failure, bars fluctuating from 5 - 3 - 2 - 1, no signal/bars searching etc... Ifeel miserable after trying out all the options changed multiple sims, tried multiple carriers, restored the phone back and have set-up as new device but the problem does not get solved... its is so frustrating that after investing on a world's most expensive phone you cannot enjoy the calling features which the phone offers which is the main thing you own the phone for.. Rest of the things are working.. The funniest part I am not able to make calls or receive calls but can access the internet..  I have tried every possible thing and really very frustrated with this iphone of mine...I hope the problem gets solved.. would anyone have any solutions to this problem.. Does it mean one should never update software as I hear that after updating to IOS.5.1 the problem has started coming and same has been with there.... Apple says its a hardware failure which is very difficult to digest as sometimes I get 5 bars and able to make and receive calls but 95% of the time I am unable to. If anyone has any solution I will be very happy if he or share can share the same. Many thanks. its so disgusting to experience this on top of this apple does not support global warranty for the phone as you need to go to the country from where you bought the phone for replacement.. Truly sad state of affairs.. very very very dissappointing.

    Have a look at this it might help

    Only the carrier that the iPhone was locked to can unlock. There you go, hacking void any support from this forum.

  • If I buy the CDMA iPhone 5 unlocked, could I use it with GSM also?

    I am planning to buy the new iPhone 5 unlocked, if I buy the CDMA model could I use it with a Nano Sim card in a GSM network, regardless of the LTE compatibilty?

    There is no such thing as an unlocked CDMA device.
    There are also no unlocked iPhones currently available, unless I've completely missed that announcement.

  • Hey Guys I Travel to the States and I am from Germany. I want to buy an iPhone 4S 8GB white Version unlocked GSM. Can I use the iPhone in Germany with every SIM Card?

    Hey Guys I Travel to the States and I am from Germany. I want to buy an iPhone 4S 8GB white Version unlocked GSM. Can I use the iPhone in Germany with every SIM Card?

    As long as you buy from an Apple retail Store (Apple owned ) an unlocked iPhone 4S it will work on GSM services worldwide
    from Apple.com
    If you buy a SIM-free iPhone, you will need to purchase a GSM-compatible micro-SIM separately. When you travel internationally, you can use a micro-SIM card for iPhone 4s from a local GSM carrier.
    The unlocked iPhone will not work with CDMA carriers such as Verizon Wireless or Sprint.
    However the warranty will NOT be valid outside the US .If you need warranty or post warranty service you will have to return the iPhone to the US in person ( cannot mail in to US )

  • Why not to be unlocked iPhone working with GSM and CDMA/LTE in one device?

    why not to be unlocked iPhone working with GSM and CDMA/LTE in one device?

    I'll explain, does Verizon unlocked iPhone 5s work with CDMA networks (with SIM or without SIM), and if I travlled to another country that provide GSM operators, does the phone will work with GSM SIM normally?

  • Can i buy iphone 4s unlocked in your appstor in usa and use in gsm net in russia?

    can i buy iphone 4s unlocked in your appstore in usa and use in gsm net in russia?

    Yes, if you go to an Apple store in the US physically, then you can purchase an unlocked iPhone 4s and is should work in Russia, but you can't do it online - there is no international delivery available online and you need a US credit card and shipping address to be able to do that, but if you go there in person, you can certainly purchase and unlocked iPhone 4s.

  • I have an iphone 4s unlocked with att prepaid plan (non-contract), everything was working perfect BUT since i update to IOS6 i can not send MMS to anybody has Android, i went to att technical center they said only apple store can fix the problem, i went..

    I have an iphone 4s unlocked with att prepaid plan (non-contract), everything was working perfect BUT since i update to IOS6 i can not send MMS to anybody has Android, i went to att technical center they said only apple store can fix the problem, i went to Apple store MANY times they could not fix it, so they gave me a new iphone 4s and they said they fixed it but they did not,iam so mad that's not fair, can somebody help me please.

    The nice thing about owning this overpriced POS is that Apple not only doesn't support it, but also doesn't want to hear about anything negative regarding it.  So I spoke to the so-called "support" people at Apple who successfully screwed up my contacts beyond repair.  I got a nice email from Apple asking me to rate the support I got.  I was actually civil and described the issue tactfully.  What do I get in return?  Nothing.  Not a damned thing!!  You're luck you've got me by the short hairs on a 2 year contract but I'm still tempted to throw this POS through the front window of the nearest Apple store!!  Not only will I be replacing this phone with a competitive product but I won't be buying anymore Apple crap.  I guess when you con 27 million people into believing your rhetoric and sales lies, you don't have to care whether some customers get screwed or not.  I'll be going back to Verizon and threatening legal action if they don't take this electronic dung heap back but I'm sure the teams of lawyers Apple and Verizon have on staff have insured that I have no rights in this matter and you're free to screw me anytime you please.  Sad. I used to love Apple as a company and your products.  Now you're just another Microsoft with more trendy looking junk.  I've had it with you.  If any of your executives are brave enough to talk to me, please contact me at your convenience.

  • HT201328 IPHONE 4 UNLOCKING PROBLEM ORANGE TO VODAFONE NETWORK

    Hi
    My problem is I had finished my contract of 24 months with orange/EE & payed £20.42 to wait for a confirmation email that did arrive after 2 weeks with unlocking process via iTunes.
    So I wanted it unlocked so it could be used with a Vodafone microsim as a gift to my  dad so I bought a new Vodafone micro sim because I had to order a new microsim with all my dads details on it &  I did what the orange email said in steps but I (never got a congratulations your iPhone is unlocked) message but I noticed it did say Vodafone uk network on top left of the iPhone 4 screen.
    But the Vodafone microsim was not the number I wanted as Vodafone had to change all the details from a standard size sim to a new micro with all my dads details as he wanted to keep the same mobile number so seeming that it was showing the Vodafone network signal & all working I finally received my dads  new Vodafone microsim with all his details etc that was on the standard sim that was in my dads old phone but when I ejected the Vodafone microsim that was working  I bought that was brand new & like I stated was working on the iPhone 4 & swapped it for my dads new micro Vodafone sim All I get is "NO SERVICE" So I went through the exact same steps on the email for unlocking my orange locked iPhone 4 again  as I did with the first voda sim but I get " No service ". I'm sorry to bother you guys especially XMAS day but its a gift for my father today as it's his Vodafone number he wants to keep on the sim they sent so I phoned Vodafone & they said the sim needs activating & could take 30 mins to 24 hours. But it's been over 24 hours & Ive turned the iPhone 4 on & off but still no service plus I reset network settings & rebooted the iPhone a few times
    It must be unlocked because  the first Vodafone microsim that I bought new recently  worked but its strange & extremely  frustrating that my dads new Vodafone microsim still says. "NO SERVICE"?
    Would you be kind enough to help me if you have any idea what I've done wrong or is there anything else I'm supposed to do or could do to get this other new Vodafone Sim working. Sorry to bother you guys but you seemed to know a lot about unlocking so i thought I'd ask you. If you can help in anyway I'd be so very very grateful as I'm running out of time  
    THANKYOU
    Merry Christmas & Happy New Year.
    Sent from my iPhone 5s

    Nothing to do with Apple what so ever 
    Only the carrier ,in this case Vodafone can authorise the unlocking of the iPhone
    The IMEI is the vehicle not the  phone number
    However to allow approval Vodafone probably  need to be able to
    see the IMEI active on their network
    You could consider buying a PAYG sim become a customer active and on
    their network and then try a new request
