I recently procured the EC200U-CN module and designed a circuit and PCB around it for my project. However, I am facing difficulties in establishing a network connection. I have tried using both Airtel 4G and Jio LTE SIM cards, but unfortunately, the module is not able to connect to the network.
Here are some details regarding my setup:
- Module: EC200U-CN
- Location: India
- SIM Cards Tested: Airtel 4G and Jio LTE
- Observation: I can detect the presence of the module through the USB ports, but I’m unable to establish network connectivity.
I have thoroughly checked the circuit and PCB design, ensuring all necessary connections are properly established. However, despite these efforts, the network connection issue persists.
I would greatly appreciate any guidance or suggestions from the community on potential reasons for this connectivity problem. Are there any specific settings or configurations that need to be taken into consideration for the EC200U-CN module in an Indian network environment? Could it be related to compatibility issues with the Airtel 4G or Jio LTE networks in India?
I am eager to hear your insights and experiences regarding this issue. If you require any further details or clarification, please let me know. Thank you in advance for your assistance!
