maybe by now the issue of "insufficient context for those unfamiliar with the subject." is less salient now. — Preceding unsigned comment added by 92.229.217.162 (talk) 23:49, 4 August 2011 (UTC)[reply]

I think you will find that an IMSI number is not capable of determining the number of the cellular phone that is being tapped. Cellular phones only transmit IMSI and TIMSI numbers to the tower, which are later translated internally within the phone company to actual dialiable numbers.

Using the IMSI or TMSI of the phone can be used to clone the phone in the case of CDMA phones. Furthermore while the IMSI is not transmitted often a silent SMS or a failed call will induce the phone to transmit its IMSI or TMSI also in and out of airplane mode while registering on the network. The ability to capture this data through passive monitoring can indeed link TMSI/IMSI to a phone number if monitoring the paging channel for the particular data. — Preceding unsigned comment added by 85.11.180.53 (talk) 20:47, 21 January 2013 (UTC)[reply]

Citation:

All mobile phones in the catchment area have no access to the network. Incoming and outgoing calls cannot be patched through for these subscribers. Only the observed person has an indirect connection.

Really? While the IMSI-catcher acts like a base station, it could retransmit all connections to the operator, using different SIMs. 212.2.96.101 (talk) 09:39, 17 November 2009 (UTC)[reply]

Citation:

Since the network access is handled with the SIM/USIM of the IMSI-catcher, the receiver cannot see the number of the calling party.

MSISDN must be send in the datagram, or it couldn't be possible to see MSISDN of the calling party from different operator, therfore IMSI-catcher should be able to retransmit MSISDN numbers as well. 212.2.96.101 (talk) 09:39, 17 November 2009 (UTC)[reply]

Citation:

Of course, this also implicates that the tapped calls are not listed in the itemized bill.

Well, a good method to make free calls? Sorry, I don't believe it. 212.2.96.101 (talk) 09:39, 17 November 2009 (UTC)[reply]

Stingray

Is this the same as what the media call "stingrays" now? It's strange that they don't even mention the term IMSI catcher.--88.73.45.204 (talk) 22:20, 21 October 2011 (UTC)[reply]

yes, this is what the Florida cops used. The Harris Corporation Stingray product is an IMSI catcher.
