Can't get cellular internet 

NX500 - ok on RJ45 plugged into WAN 

Firmware updated 

New Lyca SIM , not pin locked , ok in phone but when inserted into NX500 , I just get 'no internet ' 

I've changed the settings from EE (default before firmware upgrade) manually to what the internet says and indeed since the firmware update , I've a new profile with the same settings 

Can anyone throw any light please ?
