Can someone help me resolve this issue I’m having with my Jetpack 4510 device? There’s a green light at first, then violet, and lastly, a red light that stays on for about two seconds that’s why I cannot connect. The manual says SIM card problem. First time I’ve had this red light come on. Couldn’t resolve this issue with Tech Support. Can someone help me? I reset the device, but still there’s the red light.
