Hello. So I am using an external power supply of 5V 2A and the GSM can register to a network without issues, but when I try to send messages through Arduino, no messages are sent. Why is this happening?

I have the same type of gsm module here in Zambia 🇿🇲. The problem is that its blinking continously every after a second and that means its not connecting to the network. What should I do to solve this problem?. Thank you in advance

Hello, i have a similar PCB with SIM900, when on, the module sends RDY +CFUN: 1 +CPIN: READY +PACSP: 1 Call Ready (9600 bauds), whei send to the SIM900 la comman "AT", the module responds - AT -, dont receive - OK - . Its damage the pin TX of the PCB with SIM900? what can i do to test and verify if a need to buy another new brand module?
