Good Day. Im having problem with my project. I use arduino Uno and Sim800L module
But it doesnt seems working. I tried to call my sim card. But it cannot access any network. My sim card is cannot be reached. Also I tried sending message however its not working
My connections are ;
If your SIM is not reachable then you need to check these things,
- Is GSM module powered on properly with a 4V 2A input on VBAT pin.
- Is NETLIGHT LED blinking and at what rate?
- If NETLIGHT is not blinking then you might not turned it on properly, Did you press the PWRKEY down for 1 second?
Also, did you go through this post to find possible reasons?
Hello. I can’t see the antenna, maybe you need to soldering it.
Good observation @ALEXIS.
@potpot Is the spring lying on the table is the antenna?
RaviPujar and Alexis, thank you very much for your response to my question .
I had fixed it I fixed the antenna to my gsm module. Thank you again for the help
Glad you were able to fix it
