    FAQ About R-SIM for iPhone

    Is it safe to use R-SIM?

    It’s hard to say. Generally speaking, R-SIM is safe to unlock your iPhone if you can not afford a permanent iPhone unlocking. And the unlocking procedure of the R-SIM card does not interfere with the warranty of your iPhone device. However, it may damage your original SIM card and the new one. If it fails, you can not use any of them and turn your iPhone into a brick.

    How long does an R-SIM last?

    An R-SIM can last for as long as you keep it inserted in your SIM card tray. However, if there's an iOS upgrade on your device, the R-SIM won’t continue to work. At this time, all you have to do is buying the latest version of the R-SIM card if available.


    If your iPhone has been locked to a carrier or network up until now, thankfully, you now know there's some pocket-friendly ways to enjoy the features of more than one network.

    Keep in mind that a permanent iPhone unlocking is possible, but it will cost you more with R-SIM. Hence, you can consider the professional SIM unlocking tool WooTechy iSalvor, since it's safe and easy to use, cheap, and gives you far more liberty. Just download and give it a try!
