Broadband light on my DLC is red, again!
Last month I noticed that the broadband light on my DLC was red. After several phone calls with varying information and two tech visits, it was fixed by changing the sim card. A month later, I noticed the past two evenings, the red light came on again. Last night it went off about 5. Tonight, it is after 8 and still on..... I live in a major metropolitan area with plenty of cell towers and no issues with my cell signal on my phone. What could be the issue and do I need ANOTHER tech visit?
