We have been made aware of upcoming planned maintenance.
During the above window, the network will be performing an upgrade on one of their MME Gateways.
During the working day of 12/01/2026, the network will block new sessions connecting on the MME when they disconnect - repointing the traffic to alternate MME.
All new connections will select the other MME.
Any SIMs that remain in session on the MME when scheduled Maintenance begins will experience a disconnect and reconnect at the during the Maintenance window. These sessions will re-establish on the alternative MME(s)
No major service impact is expected; however, we recommend that you proactively monitor your device connections during the above times.
