The person travelled outside of their home country to Italy and then Malta. Their belief is that the person made contact with someone locally in one or both countries and that they would have used the mobile. This was back in September, so some time has already passed from the last known contact, but they are looking to at least validate their assumptions regarding the last known location, maybe even to the level of the mobile tower – if this data is available. </p><p class="MsoNormal"> </p><p class="MsoNormal">My high level understanding of mobile internetworking is that once the device attempted to registered on the local, the local network would need to make a query to the “home” network to allow services (inbound/outbound/etc). So in the least, the home provider would have some sort of trace of which network/country the device is registering at. </p><p class="MsoNormal"> </p><p class="MsoNormal">What would they (or the police which at the locality isn’t very tech-savvy) be asking the mobile provider to investigate/provide? Any other telecom data that they could use ? (They’ve already made requests to access information on Facebook, Yahoo and Google accounts which the person may have used)</p><p class="MsoNormal"> </p><p class="MsoNormal">Any assistance is appreciated and apologies if this is too far off topic. </p><p class="MsoNormal"> </p><p class="MsoNormal"><span style="color:#1f497d">Best Regards,</span><span style="mso-fareast-language:EN-CA"></span></p><p class="MsoNormal"><span style="color:#1f497d"> </span><span style="mso-fareast-language:EN-CA"></span></p><p class="MsoNormal"><span style="color:#1f497d">Ivan </span><span style="mso-fareast-language:EN-CA"></span></p><p class="MsoNormal"> </p></div><img src="http://t.sidekickopen06.com/e1t/o/5/f18dQhb0S7ks8dDMPbW2n0x6l2B9gXrN7sKj6v4LCS0Vf6xNj7dSCJWW64Jplz1pctGFW55kbNc1k1H6H0?si=6470560385859584&pi=e4f3080e-f839-43ce-9cdf-4131a24cc7a1" width="1" height="1" style="display:none!important;"></body></html>
