Problem with SIM registration on some ports.

Good day. We have a problem.

Periodically SIM loses registration. It happening with various SIM's of various mobile operators. Today we noticed that problem again and captured AT command log.
If we will plug that SIM into another port, it will work normally.
We have 2 non-working ports already, today was the 3rd one. And these ports are on various GSM cards.
