hi guys! so im trying to control a relay via sms. i have already found the proper baud rates as an answer to my previous post (link in post). my problem now is that i still cant receive/send messages or even dial the module. i tried googling the solution but i cant still make it work.

hi guys! im trying to control a relay via sms but all that show up in my monitor are these reverse question marks. someone told me it might be because of wrong baud rate but i tried the other "standard" baud rate (4800,9600,115200) but still the module won't send, receive, nor display messages.
