Zte Mf286d 3g/4g blinking blue

[AbleCereal]

I have recently bought the ZTE Mf286d to give Internet access to my new flat. It is set up but the 3g/4g light is flashing blue non stop. How do I get it to stay blue and connect?

According to this https://www.manualslib.com/manual/1983358/Zte-Mf286d.html?page=49 the blue light flashing is data being transferred, which is normal operation.
