What is R-SIM and what is it for?

Have you heard of R-SIM or RSIM but you are not very clear about what it is or what it is for? It’s quite common and I suppose if you’re reading this it’s because you’re in this situation, so let’s clear up those doubts.

In short, an R-SIM is an accessory for iPhones that are locked to be used only with a carrier’s network. Thanks to it, these iPhones can be used in other companies’ networks by bypassing the blocking.

RSIM, how does it work?

A few years ago it was very common for telephone operators to subsidise mobile phones. Thanks to this, customers could get terminals with a lower initial outlay, but signing agreements to stay 12, 18, 24 or more months…

In addition, these subsidised devices were also often blocked from being used on other operators’ networks and releasing them was quite complex.

In recent years things have changed quite a lot and at present this practice is not so common, although in some countries it is still frequent and this is where the MSIMS comes in.

We could say that the R-SIM is the easiest way to unlock an iPhone . At least in cases where the phone operators do not release the handsets with a simple call to their customer service.

The R-SIM is a SIM-sized but much thinner accessory that fits in the SIM tray of the iPhone . Just on top of the R-SIM you place the SIM of the operator you want to use. Thanks to this installation form, the R-SIM can intervene the SIM-iPhone communication and run a firmware that tricks the smartphone to bypass the operator lock.

In this video you can see exactly what the installation process is and also see what a real R-SIM looks like.

How to use the R-SIM

Using an R-SIM is virtually transparent to the user.

Once installed on your iPhone, you need to enter a code in the iOS Phone app (the code is usually provided by the manufacturer) to select the carrier you want to use.

Once you have selected the operator you will have to reboot the iPhone and when you turn it on again you will no longer see the wrong SIM message , but you will see that the phone is taking coverage correctly and you can start using it with your new company.

I hope that these lines have helped you understand a little better what an R-SIM is and that you no longer have any doubts about whether or not it is what you were looking for.
