How can I choose between X-SIM, R-SIM 12, R-SIM Supreme and Gevey SIM?
We get this question a lot. First, it depends on which model of iPhone you want to unlock. If you want to unlock a 4S, for example, you’ll be choosing between just Gevey SIM and R-SIM Supreme.
If you want to unlock a newer model of iPhone, however (5S and up), you’ll be choosing between our three most popular products: R-SIM 12, X-SIM and the newly released R-SIM Supreme. All work well to unlock any phone on any network, so they’re all good options.
To see which options you have for your phone, simply click on your phone model on those pretty photos above ^^.
Sometimes all SIM unlocking products are called “Gevey SIM”, because Gevey was the first well-known brand to launch the technology. (the same way that in some parts of the USA we might call all tissues “Kleenex”.)
However, Gevey doesn’t make interposer SIMs anymore. The last product they released was the Gevey Ultra-S, for the iPhone 4S. Since newer models now use the smaller nano chips, the Ultra-S won’t fit in modern iPhones.
Until recently the Gevey SIM was the only was to unlock a 4S, but the R-SIM Supreme, released in October 2018 can accommodate the larger SIM size.
We have a few units of Gevey Ultra-S still on hand, but if you’re unlocking a newer phone, chances are you’ll be choosing between X-SIM and R-SIM.
Is X-SIM better than R-SIM?
Frankly, until the Supreme was released this year: Yes, X-SIM was the better option, even though it is not as well known.
Why? One word: Setup
Some users find the R-SIM 12 setup tricky. You need to navigate the menu, choose the right options, and input an ICCID code to get it working. Not rocket science, but there are many choices to make and new users can find it tricky.
In contrast, X-SIM is a truly plug-and-play system. We almost didn’t put an instructions video for it because… it’s just so easy. Step 1: Insert the SIM+X-SIM. Step 2: DONE! Your phone is unlocked.
So even though RSIM is the better-known brand, when choosing between RSIM 12 and X-SIM, we encourage users to go with XSIM for simplicity. It costs a couple dollars more, but well worth it.
