Module sim7670C cannot send messages, cannot call, nor receive messages or calls! Ple - Tchip - 01-04-2024 Hi everybody! I'm new to the 7670C sim module and currently I still don't know how to configure it to receive, send messages and calls. I sent AT commands to it and it responded OK. But when I send messages and calls, it cannot make or receive calls and messages. Look forward to the help. Thank you so much!

Thank you for your early response. I have set the message center number and inserted the sim card completely. But it can't actually send or receive messages. I add that I have used this sim well with modules 800C and 900A. Code: AT+CPIN? Code: AT RE: Module sim7670C cannot send messages, cannot call, nor receive messages or calls!

But when tested on SIM 7670C as mentioned above, one of them failed to work with messages and phone calls. The remaining 2 SIM cards respond OK to AT commands but they also have errors, one shows an error message: SIM not inserted. AT+CPIN? +CME ERROR: SIM not inserted And the third sim says busy. AT+CPIN? +CME ERROR: SIM busy I have tested a few sim 7670C modules but all have the same problem. Really don't understand what's going on?

Ple - admin - 01-05-2024 check your power supply for SIM7670, it need large current when working. i have seen your photo, power supply by USB port, i think it's not enough for SIMCOM module.
