I have a question about the GSM 7600g-h module which I am currently using to send data by TCP (Transmission Control Protocol) .

The problem with using that kind of GSM I bought is the noise after turning it on. It did not sound when I send data to the server. What are the core causes of this?

Is there any way to settle it sufficiently without breaking?

    \$\begingroup\$ Have you read the data sheet to see if there are any clues? It might be coming from the inductor mid/top left. \$\endgroup\$

    \$\begingroup\$ Best guess: magnetostriction in the inductor due to burst current consumption. \$\endgroup\$
