Unit (LTE7480-M804) does not recognise the sim card. States no sim recognised. I can put my phones EE in, but the Vodafone will not recognise. Vodafone sim works fine in my phone.

I have set the APN settings manually, nothing, same result.

I have tried to update the firmware from current 1.00(ABRA.0)CO to (ABRA.3) or even .5. Here I get an error stating the firmware image is illegal.

Any ideas please.
