Having the latest Nokia cell phone is one thing, but having the ability to use it with any GSM service provider is just so much sweeter. If you’re not so comfortable with the software-based solution, there is the No-Key Nokia X-SIM for all your Nokia unlocking needs.
As you already be aware, any software or hardware hacks carry the risk of voiding your factory warranty, but the No-Key X-SIM keeps your warranty perfectly intact because you actually aren’t altering anything about the handset itself. All you need to do is insert the No-Key Nokia X-SIM with the SIM card of your choice and it will bypass the identification system that locks most cell phones.
The handy chip — available here for $31.69 — works with a variety of Nokia models, including: 2630, 5300, 5700, 6120c, 6110 navigator, 6500c, 6500s, N76, N95, N95 8GB, N61 8GB, E65, N73, N80, 6120c, N75, 6300, as well as all DCT4 and BB5 Nokia mobile phones.
