note

  1. how ensure the setting is correct and the according the GSM SIM setting .
  2. how to post data through HTTP protocol
    we followed manual and tried AT CMD but unfortunately result is failed

Can you share the code you tried? The most common failure I’ve seen with a SIM connections is incorrectly counting the number of bytes sent. Also, you may have formatted your request to ThingSpeak incorrectly. Are you able to update your channel with a http command in yout web browser? Once you have that syntax correct you can copy to your code. The ThingSpeak library for Arduino includes some AT command examples. They may need to be adapted to your hardware, but I think that will provide you some great hints.

Hi,

Thanks for the help. The code is working now with your suggestion of changing the bytes sent.
