How to switch between SIM1 and SIM2 for cellular connectivity on the EC5000?
1. Open Terminal and switch to root: sudo -s. 2. Run the command to switch SIM cards:
- Switch to SIM1:
echo 0 > /sys/class/gpio/PG.06/value Switch to SIM2: echo 1 > /sys/class/gpio/PG.06/value
Ensure the cellular antenna is properly installed, and the SIM card is valid (inserted with the device powered off).
