We have been made aware that since 10/02/2021 within Vodafone CDRs, specifically type SMS, that Vodafone are using false IMEIs and IMSIs when there is an SMS sent over Wi-Fi.
When an SMS is sent or received and either the sender and/or the recipient is on Wi-Fi, there may be a false IMSI and/or false IMEI created.
These are occurring in place of the actual IMEI or IMSI as the network does not need to see or keep them for the SMS to be sent or received.
- IMEI 350000003535350
- IMSI 234159999999999
