Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Colour and pattern of the phone light
- Who:
- you, looking at the front of the router.
- How:
- look at the phone icon on the left and note whether it is solid red, blinking red or off, and how the Internet light looks.
- Result that matters:
- telling solid red from blinking red and knowing whether Internet is also failing.
- If phone solid red or off and Internet solid blue:
- it is a voice only problem; restart the router.
- If Internet is also off or red:
- fix the connection first, because the landline depends on it.
- Evidence to keep:
- photo of the front of the router with the lights.

Restart the router
- Who:
- you.
- How:

- solved.
- If it is still red or off after the restart:
- contact Movistar technical support.

What it means
According to Movistar's official pages about the Movistar Router lights (fibre HGU), the phone light, a phone shape on the left, is solid blue when the service works, blinking blue while connecting and solid green during a call. Red or off is a service problem and calls are not possible; the blog adds that when red the router cannot reach the network to provide phone service, which depends on the fibre. Blinking red is a different case (voice registration). Other models may have a different light layout.
