A SIM trace is a high level 'check' on all activity undertaken by the SIM. A trace can identify operations such as which network the SIM is attached to, a time stamp of the latest data activity, PDP session lengths, any SMS successfully sent and received and more over a selected time period.
Traces are useful during investigations into lack of SIM connectivity as they pinpoint exactly where the reason for failure originates. Whilst it does not specifically tell us what the problem is, we can narrow down where it may lie.
If you need a SIM trace, please submit a request, quoting the SIM MSISDN, IMSI or ICC number and we will run this for you.
Please note, it can take up to 24 hours to retrieve the logs from a real time trace.
