What is R-sim?

This method uses the latest ICCID exploit found in Apple iOS and R-sim.

R-SIM developed by RGKNSE is the most popular iPhone Unlock Hardware on the market as of today. R-sim unlock card or simply Rsim is one of the tools that is used to network-unlock Apple mobile devices such as iPhone and iPad. The following number shows version of the device e.g. R-sim 15. At the moment of this article there has been more than 15 version of this device.

R-sim card is a SIM interposer that sits on top of your regular SIM card and spoofs your iPhone into thinking it is operating on the Mobile Network it is locked to.

How toinstall R-sim 15 unlock card

If you are a lucky owner of the latest iPhone model that is locked to a certain wireless carrier you are better off getting the latest version of Rsim as the higher the version of R-sim the more chances you have that it will support your phone model and iOS version. Always verify if your particular model is supported to avoid compatibility issues. For earlier phone models/iOS versions you can use earlier R-sim versions (see the version history below)

R-sim hardware installation

The process of Rsim installation as you can see is pretty simple and doesn’t require any technical knowledge whatsoever. It will vary depending on different version of the interposer slightly e.g. Rsim 15 has two cards in one. It can be torn apart with one part used for newest iPhone 11 and the other for older Apple iPhone models.

  • Remove your sim card from you cell phone
  • Place R-sim inside your SIM card tray
  • Place your SIM card on top of the chip
  • Insert the SIM card tray back into the phone

Does unlocking with Rsim require jailbreaking?

Jailbreaking is a process of removing software restrictions imposed by Apple. By escalating privileges it permits root access in Apple’s iOS. It allows you to install apps that haven’t been approved by Apple and customize your phone’s interface.

Gone are those days when installing Rsim required jailbreaking. Nowadays R-sim can operate without a need to jailbreak your iPhone.

Pros and Cons of hardware iPhone unlocking

After seeing how simple it is to unlock your iPhone mobile phone you must be thinking “What’s the catch?”. Does it mean that I don’t have to pay for expensive iPhone factory unlock and just use the R-sim unlock card?

What are the Pros?

Hardware unlocking using R-sim card is definitely cheap and requires minimal installation. Just pop in the card and start dialing. This is the major Pro of this method.

What are the Cons?

  • Some users of unlock sim cards report sudden dropped calls and sound distortion during calls
  • As each version of Rsim is custom tailored to phone’s iOS and model number it is restricted by the currently supported versions. If you are using Rsim I recommend disabling OTG firmware updates. See this article for more information on how to disable OTA automatic updates
  • May damage your SIM card tray, Squeezing both the SIM card and the interposer inside your phone is not a design feature after all
  • Hardware unlock using R-sim or similar unlock cards is not permanent. The cell phone will remain unlocked only while the unlock chip is physically in contact with your SIM card


The decision to use or not use hardware unlocking is yours and depends if you can afford a permanent iPhone unlock. Factory unlocking (IMEI unlock) is permanent and safe. Your phone will remain unlocked even after updating firmware. But it will cost you 3 to 7 times that of the R-sim unlock card.

Please note that if your Apple mobile device is blacklisted, network unlocking will not fix that issue. You can use Blacklist check service to assure that your device has “Clean title”. Blacklisted device can be used only outside of the country where they were originally blacklisted e.g. your iPhone X was bought on Ebay and originally locked to AT&T, that phone had been reported lost or stolen, IMEI number of that phone is now in the carrier’s black list meaning that you will not be able to use it on any of the US carrier.

If after long deliberation you have decided to go with R-sim unlock card vs. IMEI factory unlocking I recommend this site.
