Shop R-SIM 12 for cheap iPhone unlocks

What are the advantages and disadvantages of R-SIM 12?

What is an RSIM?

The R-SIM 12 is a way to unlock an iPhone that has been locked to one carrier.

A new version is released each year: RSIM 9, RSIM 10, RSIM 11, etc… The R-SIM 12 is the most recent version for 2018

It’s an interposer SIM, meaning it’s a little circuit that sits on top of your regular SIM inside your iPhone to allow a phone that had been “locked” to one network to be used with any network of your choice.

What are the advantages of using R-SIM 12 to unlock a phone?

The R-SIM 12 is:

  • Inexpensive: costs less than $20
  • Safe: doesn’t void your warranty
  • Effective: works with a wide range of carriers and countries. Your iPhone will operate the same as a factory unlocked device including SMS, data and calls
  • Compatible: works for all iPhone models since iPhone 5S, including iPhone 6, 6S, iPhone 7, iPhone 8, iPhone X, and iPhone XS
  • Updateable: works on all iOS versions, up to an including 11.4.1, iOS 12, and all future updates
  • Relatively easy to use (more on this below!)

 

What are the disadvantages of R-SIM 12?

Here are some of the drawbacks:

  • Not instant: it’s a physical product that needs to ship to you, so shipping takes a few days
  • iPhone only: if you’re looking to unlock an Android device… sorry, RSIM is made specifically for iPhone
  • Manual updates: when you update your iOS, you may need to enter a 20-digit number called an ICCID code. This takes 1-2 minutes and the codes are always free on our website. More on this below.

 

Why does the R-SIM need “manual updates”? Is this hard to do?

Although R-SIM12 is compatible with all current and future iOS versions, when you upgrade to the newest iOS you will need to type in an ICCID code in order to update the software.

The ICCID code is 20 digits, and entered through a special RSIM menu in your iPhone. We always list the most recent ICCID here so you won’t need to look far to find it. The ICCID codes are free and always will be.

Entering the code is easy and the whole thing shouldn’t take more than 1 or 2 minutes, but of course, it would be even better if it was done automatically.

If you really hate the idea of manual updates, we recommend ordering X-SIM: it’s very similar to R-SIM, works on all iPhones, costs just a few dollars more, but all updates are done automatically: no setup menu, no update codes, everything is automatic.

Is R-SIM 12 a good way to unlock my iPhone?

If you like a wallet-friendly option and are willing to wait a few days and enter a code in your phone once or twice per year, we definitely recommend the R-SIM 12 as the most affordable way to safely and effectively unlock an iPhone.

Nervous about the ICCID codes? Don’t be! We provide full support and instructions for our customers, so you’ll never feel alone. For a little more convenience, X-SIM is another similar option with automatic updates.

  1. Can you use the same r sim on a different device after using it on a previous device?

    1. Gevey Store

      Hi Ali. Yes, you can move it to another phone later. But, R-SIM12 will only unlock one phone at a time. R-SIM Supreme is a one-time unlock that can be used on multiple phones at once.

      1. Will it work to unlock verizon us iphone 6s

        1. Yes, the most recent version (RSIM 15 or 14+) will work with Verizon iPhone 6s

  2. Hello,

    I got an iphone 6s locked to straight talk. I need to unlock it now using RSIM-12.

    Can I have the latest ICCID number please.

    1. Gevey Store

      Hi Raghav, you can find the latest ICCID code here: http://geveystore.com/iccid-code-r-sim/

    I’m trying to activate an at&t prepaid SIM card for use with my soon-to-be unlocked iPhone XR (using R-sim 14). I had T-mobile and now switching to att. It requires the IMEI number for my phone. My IMEI is blocked due to no payment on the T-mobile network (I’ve checked). How can I get around this?

    1. Rebecca Murphy

      I figured out the issue! I have a clean IMEI on other networks, just not T-mobile. Once the phone is unlocked it should be good.

    2. Hi I’m wondering if r-sim will work after it has worked one 1 device can I use it again on another device

      1. Hi, Harry. Yes, if you remove it from one iPhone it will still work on an any number of other iPhones. It only keeps the phone unlocked while RSIM is still inside the phone. But, keep in mind that with R-SIM 15 you get 2 RSIM (for normal SIM trays) so you could unlock 2 phones at one time. (anything with a regular SIM tray, ie not XR/XSMax etc)

  4. Can you use another SIM card to replace the one you used to install the r sim

    1. Gevey Store

      Hi Anthony, yes, once you have R-SIM you can use any SIM card with your phone- you will just need to do the R-SIM setup (enter ICCID) each time you change the SIM card.

  5. Recently purchased R-SIM 14 on Ebay , did not arrive yet, perhaps I should have purchased it from you. Have XS Max, that is locked to Xfinity mobile. Want to use an active T-Mobile sim and phone #. Was not aware that updates may not work. Maybe X-Sim is a better way to go. Please advise. Thanks

  6. Hello, I live in Japan and I recently bought a new phone. I still have my almost 3 year old iPhone 7 which is carrier locked. I wonder if I can use a different network while never leaving japan and if I change my mind revert back to the original carrier. I asked this because permanent unlock offered online said thaat once it is unlocked, I can never use it again in japan. But I wont be leaving Japan. I will just hop on another network.

    1. Gevey Store

      Hi, Toya. Yes, R-SIM is perfect for this. Keep it in the phone while you want to use it unlocked. Then, if you want to use the original carrier again, just remove the R-SIM and use the phone as usual.

  7. I don’t have PayPal…Can’t I just pay with my credit card.

    1. Gevey Store

      Hi, Ralph. Sure, you can pay with your credit card even without a PayPal account. Once you enter your address and click “Proceed to Paypal”, there will be an option to log in at the top of the page, or, just click the grey button at the bottom of the page to pay with your credit card without using a PayPal account.

  8. I have an iPhone XS Max bought from US. It is carrier locked by AT&T. Would RSim help me use the phone here in India? If yes, please tell me if you can ship this to India. Thanks!

    1. Hi, Munish. Yes, it will work and we do ship worldwide including India.

  9. I’ve been using a r sim on my iPhone 7plus since august but recently it has stopped working. How long does these chips last and do i need a new one?

  10. Hey guys. I want to update to iOS 13, do I need the 20 digit code? If so how can I get it?

    1. Hi, Eric. The 20-digit code is called the ICCID, we always list the most recent one here on our website: https://geveystore.com/iccid-code-r-sim/

  11. Does the R-sim 12 work with ios 13. And in the future ios’s updates or i have to change it to a newer one?

    1. Hi, Zaki. Yes, it works on iOS 13 and above. It will continue to work on future iOS updates.

  12. How long does shipment take to London

    1. Hi, Adjoa. There could be delays with the holidays + winter weather, bus usually shipments to London take 5-10 business days.

  13. Good morning
    A friend just told me that with the R-sim there is no way I can update my phone so I want to find out if it’s true

    1. Gevey Store

      Hi Lynne, this is a common myth. In fact, you can still update your phone to the latest iOS with R-SIM Gevey SIM. You will simply need to repeat the setup steps after each update. It only takes a few minutes each time 🙂

  14. I HAVE MY IPHONE SE WITH IOS 13.3.1 Recommend me GEVEY SIM FOR MY PHONE ALSO SHIPMENT TO PAKISTAN HOW MUCH TIME IS REQUIRED

    1. Gevey Store

      Hi Amey, You can order R-SIM 15 Gevey SIM here. For Pakistan it might take 2-3 weeks, depending on local mail service. Some countries are faster (USA, Europe, etc), but in India and Pakistan we tend to see delays in customs and the local post service. Sorry about that.

  15. I don’t see an option for the 11 pro max. Also will this work with the new Visible phone network?

    1. Gevey Store

      Hi Jay, RSIM 15 will work with iPhone 11 Pro Max. It will work with all phone networks, including Visible (who happen to be owned by Verizon). 🙂
