Is it a SMS notification to submit paper materials for transfer?

Maybe, because the status is notified in real time.

From the online pre-acceptance, every time the material status is updated, a text message will be sent to the mobile phone of the handling personnel to inform the unit in time, so that the handling personnel of the unit can know the material status in time and track the progress of handling.

On the day of publicity, before the list on the website of the Bureau of Human Resources and Social Security comes out, you will receive a short message: XXX, the holder of the Bureau of Human Resources and Social Security, has passed the application for permanent residence in Shanghai.
