Mobile number analyser
This is a useful resources for mobile telephone evidence analysis... although I would suspect some people in the field know about it. There are quite a number of these free online services on the Internet. The only observation I would make is that online services like these usually provide identification only of the mobile/country code (MCC etc) and mobile/network code (MNC etc) and so on. I would certainly not enter my complete IMSI (International Mobile Subscriber Identity) or the SSN (SIM Serial Number) from your the SIM card, IMEI etc, simply from a privacy pointof view, apart from anything else.
