What does a blue power light mean on theZyxel NR5103EV2?

[Psmithson]

Hi,

Every time I google "blue light" on this router, it tells me about signal strength etc. I'm used to the middle two lights going blue or green but today, the power light has gone blue. It's normally green. Here's a poor quality photo. You can just about see that the top 3 lights are blue and the bottom one is green.

What does that mean?

According to the manual, a blue power light means one or more unread sms messages https://device.report/manual/10057487

Great find @Officina-red!

@Psmithson it doesn't sound like anything is physically wrong with your router, but if you have a look about the router Admin, there'll be an SMS feature that you can use to send/receive texts. Most customers won't make much use of this, but most likely your SIM has just received a service message from us.

Took another picture. This time, only the top 2 are blue but wanted a picture that showed the colours more clearly. I'm used to that signal one going in and out. Just the power light that is puzzling me
