iPhone 4- Gevey sim unlock useful tips

October 31

If you are using Gevey unlock and want to upgrade your iPhone to ios 5 , do not directly update it through iTunes. Use redsnow and create a custom os bundle which preserves the old baseband. Detailed steps can be found at – Update to iOS 5 by preserving baseband

After installing iOS 5 you need to activate the phone. Activation is different from unlocking . To activate the phone you will require an original sim (carrier to which the phone is locked). If you do not have the original sim, close iTunes and use redsnow to jailbreak the phone. After jailbreaking, open iTunes and activate the phone.

Now insert your Gevey sim to unlock the iPhone. It works perfectly on iOS 5 and baseband 4.10.1.

Gevey sim problems that I have faced and the solutions

– After the sync with iTunes (over USB), Gevey sim stopped working (you will see no service message). It seems Apple is sending some instructions to phone to disable the Gevey sim. I removed the sim and inserted it again. Then Gevey sim started working.

– To get rid of this problem, I am disconnecting the internet from my machine (on which iTunes is running) while syncing the phone. So far, I did not face any problem with this method.

– After syncing the phone with iTunes over Wi-Fi, Gevey sim stopped working and I spent a lot of time to make it work. One solution that I found is – sync the phone with iTunes (disconnect internet from laptop) over USB then remove the sim and insert it again. Hereafter Gevey sim worked well .

– After downloading GPRS or 3G settings, those settings did not work. To make it work, I restarted the phone, removed the sim and inserted it again.

– If none of those techniques work or if you see invalid sim message: Remove & insert the sim. After few minutes you will see No service message. Dial 112 and end the call in a minute. Turn on airpot and off it in a minute. It will show SIM Failure message. You might get signal by this time. If not, it might have shown you invalid sim message. Now remove the sim and insert it again. And do not do anything. You will see the signal in few minutes.

– If you have jailbroken iOS 5 (currently only tethered jailbreak is available), when you restart the phone you have to use redsnow just boot option to make the phone work. If you Want to restart your phone without connecting it to laptop, one alternative is, use of software restart called respring. Download sbsettings from Cydia and it will show respring option. Now on-wards whenever you want to restart the phone, use respring option.

– Turning on 3g may drops the signal, then remove and insert the sim, gevey displays accept message. Click on it. Wait for 1 minute and dial 112 and hangup. Turn on airplane mode till you see no sim card installed message. Turn off airplane mode. It displays the signal now (even for gevey ultra sim, you have to follow all the steps).

– This technique worked for all kind of signal problems: Remove the sim card when you notice no service message. If you see other messages like invalid sim, turn on and off airplane mode until you see no service message. Insert sim, then gevey displays accept message. Click on it. Wait for 1 minute (you may notice no service message) and dial 112 and hangup. Turn on airplane mode till you see no sim card installed message. Turn off airplane mode. Wait for few seconds. You will notice sim failure, invalid sim message. Later it starts searching for signal and displays the full signal (all the steps are necessary even for gevey ultra sim) .

– Turning on 3g sometimes may show only one signal bar and slowly drops the signal. To get rid of this problem, always first turn on cellular data then turn on 3g.

[Update: 01-Feb-2012]
Gevey sim is working with iOS 5.0.1 (base band 4.10.01). Preserver base band before updating it – Update iOS 5.0.1 by preserving baseband

It is good to update to 5.0.1 because untether jailbreak is available. Which means you can turn on/off phone happily.

[Update: 14-Feb-2012]
When you want to use internet, Turning on cellular data may not work. If it does not work turn on cellular data and data roaming.

[Update: 26-Apr-2012]
Gevey sim is no more required. You can directly unlock your iPhone running on any baseband with SAM unlock method. Details are available at –

No more gevey sim problems …..

[Update: 03-May-2012]
SAM unlock is no more working. Now the only unlock solution available is Gevey sim. Latest version of gevey sim (Ultra S) also supports iPhone4 – 4.11.08 baseband.

    GEVEY will not work with CYDIA on iOS5.

    I can confirm that iOS5 with preserved baseband you need to avoid jailbreaking else gevey will stop working and you have to restore again to get rid of cydia.

    Kindly confirm if your phone is jailbreaked(semi) and your are on GEVEY

      My phone (iPhone 4) is tethered jailbroked and I am using Gevey unlock. GEVEY is working with cydia on iOS5 (preserved baseband). I’ve been using this since the day one of iOS 5 release.

  7. Question

    December 4, 2011 at 10:29 am

    Lets say I unlocked my iphone 4 4.3.5 using gevey sim and the only jailbreak option I have for 4.3.5 is redsn0w tethered.

    My question is, if my iphone dies and I have to reboot it using redsn0w…will that affects my gevey sim? do i have to go through the whole dial 112 etc. to unlock it again?.

    • Satish B

      December 5, 2011 at 7:53 pm

      If you reboot the phone, you have to go through all the steps. If you do not want to do all those steps, buy a gevey ultra sim. It costs around 10$ and automatically pickup the signal.

      • Question

        December 6, 2011 at 7:37 am

        I bought the gevey supreme sim, apparently I was told it do the same as ultra sim. I unlocked it with the 112 method.. and after turning it off then on again.. It automatically pickup the signal.

        So if Im going to reboot my phone using redsn0w, does that mean I have to do the 112 steps again?

        I want to know before I jailbreak my phone.. and wasn’t sure if the tethered and the reboot will affects the gevey sim,

        • Satish B

          December 6, 2011 at 8:32 am

          jailbreak will not affect the gevey sim. After you boot with redsn0w, as you are having supreme sim, the phone automatically pickups the signal. I am using gevey ultra on my iphone 4 (ios5 tethered jailbreak).

    I have one and don’t know what to do with this (iPhone 4S).

    • Satish B

      December 11, 2011 at 11:37 pm

      Currently no unlock is available for iPhone 4s. May be you can go for permanent unlock by contacting some agents and they will charge around $60.

    • Satish B

      February 14, 2012 at 9:27 pm

      First download & configure cellular network settings, if you don’t know call your carrier customer care and ask them for settings. After downloading the settings restart your phone. Later turning on both cellular data and data roaming might solve the problem.

      • iwayan santika

        February 16, 2012 at 9:14 am

        do the letest version of givey can solve the internet problem?

        • satish b

          February 16, 2012 at 6:36 pm

          You dont need download any app for settings. Reset all the network settings then your carrier automatically detects the required settings.

  18. iwayan santika

    February 16, 2012 at 9:06 am

    I found your post through google. My iphone 4 is currently at 04.10.01. I have the gevey sim in already with service however whenever I shut off my phone, I have to do the steps all over again. Is there any way around this?Also, it wont save my number in the settings – not sure if that matters or not. My phone usually dies at some point or another so this is what really worries. please let me know if you have any advice or any solutions for this problem! thanks in advanced!!

    • Satish B

      March 13, 2012 at 8:44 pm

      Seems you are having an older gevey sim . Purchase a Gevey ultra sim. Gevey ultra does not require all those steps .it automatically detects the signal upon mobile restart.

      Check the gevey version :Settings- general – about- carrier – carrier lab v11.0

      Gevey ultra will have versions greater than 11.0

      Turn on ‘Data Roaming’ along with ‘Cellular Data’. That might help.

    I’m having a new issue. I currently ugraded (preserved baseband) to 5.1.1 Everything is working, but only for 1-2 minutes. After that, I get “INVALID SIM” after it searches for a bit. I’ve had this gevey sim, and it’s been working perfectly for over a year.

    Very confused why this is suddenly happening.

    • Satish B

      May 28, 2012 at 6:39 pm

      sorry I am not sure about the problem. May be 5.1.1 screwed up gevey sim.

  24. aaaa

    May 28, 2012 at 2:18 pm

    Oh and under settings/about it’s “Carrier Lab 12.0” Not sure if this is new or old?

    Hi Satish,

    Thanks for the awesome post man..
    it was really great.

    I am facing some issues like

    1) when i go through area with weak signals i get No service thing after that i leave that No service still persist.
    This does not happens regularly but 5 out of 10 times.

    2) When i turned on 3G, i was not able to make any calls, there was message call failed.
    this still persisted even if i turned 3G off.

    3) Every time i get No service, i have to take my Sim out and re insert it?
    isn’t there any work around for this?

    I am using iPhone 4 IOS 4.3.3 baseband 4.10.01
    India, Vodafone Network operator.
    in Settings -> About -> Carrier Vodafone 10 is displayed.

    • Satish B

      June 4, 2012 at 7:08 pm

      1) latest gevey sim will solve the problem. It automatically capture the signal when you move from weak signal to strong signal place.
      2) I dont know
      3) When you notice no service – go to settings->phone->sim applications. Here you will find gevey sim related options. Click on any option. It will show gevey accept message on screen. (if you don’t find sim applications menu, you have to remove and insert the sim).
