Description

<b>Subject: </b> Notification - CR00015011 <b>Change ID: </b>CR00015011 <b>Description: </b> As part of CSL's continuous network improvement programme, we will be upgrading the iot.cslm2m.com APN in collaboration with Tele2 and migrating the service to a dedicated routing domain. <b>Expected Impact: </b> During the maintenance activity, active SIM data sessions connected to the APN will be briefly disconnected and will automatically re-establish once the migration is complete. Enhanced monitoring and operational safeguards will be in place throughout the maintenance window to ensure any unexpected issues are quickly identified and resolved. <b>Reason for Change: </b> This activity forms part of CSL's ongoing network enhancement programme. Migrating the iot.cslm2m.com APN to a dedicated routing domain will provide improved service stability, optimized performance, and increased operational resilience.
