How to unlock the iPhone 4S using the R-SIM interposer

By , Mar 5, 2012

I’ll admit that I’ve never used a Gevey SIM interposer, or anything like it in the past, but I figured I’d give it a shot with the iPhone 4S.

The iPhone 4S has its own special SIM interposer called the R-SIM II Ultra S, which was recently released.

I’m happy to report that this is by far the easiest method for “unlocking” your iPhone 4S, and using it with T-Mobile or virtually any other GSM carrier. And guess what, no jailbreak is required.

Check out our review of the iPhone 4S R-SIM tool inside…

How to Unlock Your iPhone 4S using the Gevey R-SIM Ulta S II:

Step 1: Remove your SIM tray from your iPhone 4S.

Step 2: Place the R-SIM in the holder that comes with it, and place your SIM card from your desired GSM provider on top of the R-SIM.

Step 3: Place the combined SIM tray and R-SIM + SIM card in your iPhone 4S and wait until you see the carrier name for the SIM card you wish to use.

Since there’s currently no version of UltraSn0w that works with jailbroken iPhone 4S’ unlocking options aren’t nearly as plentiful as they have been on pre-4S devices.

The R-SIM is by far your best bet for using your factory locked iPhone 4S on other carriers outside of purchasing a factory unlocked phone.

What’s even better is that no 112 dialing is required. It’s literally a plug and play device.

That was one of my stipulations before even attempting to use this device — I didn’t want to dial 112 and call emergency services unnecessarily. That’s just inconsiderate in my opinion, especially when there are people who are calling that service in dire need of assistance.

Unbeknownst to me, the first device they sent to me did require you to dial 112. In fact, I tweeted about it when it first arrived, but as you can see, I never reviewed it. That’s because I kindly told them that I wasn’t willing to review the device if it used 112.

Thankfully, they contacted me and stated that version 2 of the device was just released, and they would be sending it my way. Version 2, as it turns out, requires no 112 dialing.

So that is why you see this video review today, as I just received version 2, and I’m happy to report that it works just as advertised.

Thanks to Jason over at Each Supplier for working with me and my interesting demands. You can purchase your own R-SIM at Each Supplier’s website.

Let me know what you think. Would you consider taking this route to unlock your iPhone 4S for use with other carriers?

    Can the device be used more than once? Can I use it to unlock my phone to work on a USA carrier (I am Canadian) when I travel to the states and then use it again to unlock to use with a European Carrier when I travel there?

    • Juan Flor

      Yes once its unlocked you can use any carrier even if there different carriers in different regions with the same R-SIM adapter, as long as they are GSM

    Does it work on a Verizon 4S

  • Anonymous

    Would this work for a Verizon 4S to get either T-Mobile or ATT ?? Anyone know?

    • http://profile.yahoo.com/Q4W77B44GQXQ6DM5IFRYCPETJU y2khang

      Yes, it can unlock Verizon 4s but you have to use R Sim II Ultra S or R Sim 3. And you need to Jailbreak and do some small trick with your iphone before using it.

      • francisco_08

        @y2khang would you mind sharing the small tricks that have to be done, thax.

    • http://www.facebook.com/iGeek1218 Rodney Coleman

      No it does not unlock Verizon or sprint iPhones…

      • Mordechai Eliyahu

        sprint yes, verizon no

  • http://twitter.com/Paik4Life Paik4Life

    I’d be curious as to see a comparison between GPP, Gevey Ultra S, and R-Sim. R-Sim seems to be by far cheaper than the competitors but it also seems to take the longest from the videos I’ve seen.

    do anyone know if it work with iphone 4 ?

    • Mordechai Eliyahu

      no

  • http://twitter.com/TarekMMD Tarek

    Does this work for the iPhone 4? I like the idea that you don’t have to jailbreak to do this.

    Although I had my iPhone 4 jailbroken for quite a while before upgrading to 5.0.1, I have since given up the jailbreak because of the bugginess of some of the software. I said ‘some’ not ‘all’ jailbreak software.

    I like the standard 5.0.1 and just want to unlock for overseas travel.

    Any information on using this technique for iPhone 4?

    • http://twitter.com/TarekMMD Tarek

      the website says that it only works for iPhone 4s, not the 4.

      I’ll be bringing my ATT iPhone 4S to Vietnam next month. Will this unlock it for Vietnam and several other SE Asia countries? If so, consider it DONE! ;)

  • http://twitter.com/PakoBahena Pako

    Does this let you activate IMessage or FaceTime? I got the Gevey Sim for IPhone 4 but I don’t like the fact that you could only use your Email and not your phone number.

    Jeff,
    I have two questions.
    1. Does it matter what firmware you have installed on the 4s.
    2. I bought my phone in Japan will it work in the US with this and vice versa because they normally don’t?

      • vigan zdi

        iphone 4s , all i can say is it worked than it stoped after the reboot, i ve contacted them and they will ship replacement. i am kinda sure that its the real deal , just a bad luck i guess. But i cannot fully recommend it without proper testing. But i will come back for sure, after i receive the new r-sim.

    Hi.. I’ve used this product on my locked iPhone 4s (sprint). Good news is it worked very well on my iPhone 4s. I’m using it from last 2 days on vodafone gsm network. For 3G you have to activate voice roaming option in general option bar. It rocks. Keep up the good work. Only I’m not sure of updating to latest iOS 5.1

      How did u do it ?

  • Kory Turner

    I don’t see that anyone has clarified something major…
    The author states that he is reviewing a “Gevey SIM interposer” and states “How to Unlock Your iPhone 4S using the Gevey R-SIM Ulta S II”, but this name is a combination of two different interposers:
    applenberry’s “GEVEY Ultra S” – currently $59.99 on applenberry’s website:
    http://applenberry.com/store/gevey-sim/gevey-ultra-s
    and Rgknse’s “R-SIM II Ultra S” – currently $61.59 on Rgknse’s website:
    http://www.rgknse.com/r-sim-unlock-for-iphone-4s-rgknse.html
    Also, the author provided a link to purchase this R-SIM from Each Supplier’s website, which sells Rgknse’s “R-SIM II Ultra S” – currently $23.38. That same link to Each Supplier’s website states “If your carrier is not list in the default list, please try to order GEVEY ULTR S”

    It seems the product reviewed wasn’t GEVEY, but hopefully that just means the Rgknse “R-SIM II Ultra S” sold on Each Supplier’s website for $23.38 actually works…

    • http://www.iDownloadBlog.com Sebastien

      No, Jeff didn’t say he was going to review a Gevey SIM. He said “I’ll admit that I’ve never used a Gevey SIM interposer, or anything like it in the past, but I figured I’d give it a shot with the iPhone 4S.” This means that despite the fact he never tried anything like a Gevey SIM interposer, he will review something similar to that, namely the R-SIM.

      • Kory Turner

        You’re correct. I mis-read the “or anything like it in the past”, but that doesn’t explain:
