 have this mobile 4G dongle. Not used it it for probably 3 years. I can sign I to EE but get this error, I can’t “call 150” because that takes me to Sky. If I click on the EE help link it returns 404.  
is there a way to fix this?

Hi @Antmusic1 

After 3 years your SIM is likely dead. 

Try a new PAYG SIM. 

Thanks
