What can we tell you about this: The activity will take place throughout the maintenance window. There will be a brief drop and reconnection during the maintenance window. This could impact both PSMS MO and PSMS MT submits as well as any Bulk A2P and P2A messages. This will impact the PSMS platform which will see a delay with PSMS MT.
Please note, every effort will be made to mitigate the effect on our customers experience during the work but a service outage is expected.
