No-key Nokia X-SIM unlocks Nokia phones to work on any network; Warranty stays intact
Posted by Dusan on Wednesday, February 27th, 2008 at 2:34 am under Nokia, General

Here’s a neat solution for unlocking a number of Nokia phones which doesn’t require any software-based hacking. Rather, similar to iPhone unlocking solution - TurboSIM, the No-key Nokia X-SIM uses (actually it is) a special SIM card that unlocks the phone to work on any network.
The working theory of the X-SIM is that each phone operates on an identification system. The mobile phone checks if the SIM card matches the operator and if so, it opens. The X-SIM card gives a signal to the Nokia mobile phone simulating the original SIM card, so phone never really unlocks - it just allows the user to operate in any network. It can still maintain the original warranty and can also install any of the latest firmware from Nokia without problems. So, there is no risk unlocking and no risk of doing any harm to the phone.
According to OneStopChina which sells the SIM card, the X-SIM has been tested on a number of Nokia phones, including such models as E65, N73, N95, N95 8GB, 6500, and others. However, they are warning the No-key Nokia X-SIM may not work on all operator’s networks in the world. Still, their solution costs $31.69 and if it works, you’ll save much more in the next 6 months by using some other network’s voice plan… Full release is available from here.

Just want everyone to know that I gambled $36 (w/shipping)for a No Key X-Sim at unlockcellular.com in the U.S. and it worked!!
I have a Nokia 6131 that is one of the non-unlockable BB5 models, network-locked to Personal Telecom in Argentina. It has a pretty firm SIM latch so I tried to just stack the two cards together but they didn’t make a connection and I was getting the ‘No SIM Card’ message. I tried it again after cutting the corner out of my California AT&T SIM and got the same result. BUT, after using the pre-mounted adhesive on the No Key to stick it on the SIM, it worked like a champ.
I also tried switching it back to my regular unlocked phone and that still worked too, so I can switch back & forth at will. I just hope the damned providers don’t get on to Nokia to reverse-engineer this thing…
Good luck!

Now thats sweet. I have been considering switching to a GSM service but didn’t want to go through the pain of unlocking my Nokia phone (that’s what i would have if i decided to switch). Now with this, I can rest easy. I’m tired…
