If you only have a solid red light on the camera and the blue light is not coming on, we need you to try the following things:
Step 1. Make sure the plastic has been taken off the batteries and fully charge it before using the camera. If this doesn't work, move on to step 2.
Step 2. Make sure the Simcard has data credit and the simcard works on your phone or another device. Check this by connecting to the internet (Try to watch a video on youtube). If you have only just activated your Simcard then it can take up to 24 hours to work. If this doesn't work, move on to step 3.
