I moved your topic to an appropriate forum category @4dithy4n .
In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is the second time I have had to ask you this in less than a week. If you won't respond to polite requests, we will be forced to resort to giving you an account suspension to get your attention. I don't want to do that, and I'm sure you don't want to be suspended either.
Correct topic categorization is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
could you give a link to the specific simcom a7672s module? e.g. is it on a HAT or a separate PCB?
how have you attempted to interface the A7672S to the RPi 3B+?
e.g. serial to GPIO13 UART Tx and GPIO15 UART Rx?
EDIT: what programming language do you intend to use to communicate with the A7672S? e.g. C++, Python, Java, etc
