Institutions have been unable to get through SMEs.

What you want to ask is what if the public institution can't get through to the small and medium-sized enterprises? The steps are as follows:

1. First, make sure the phone number of the small and medium-sized enterprise is correct, and try to dial again and again.

Secondly, try to use other communication methods, such as email or SMS, to get in touch.

3. Call the reserved telephone number of the enterprise business license.
