Anyone else not registering on network in Falmouth?

For the past two days my phone is not registering my sim card onto the network in Falmouth? Service status just keeps saying there is a signifigant issue in the area and will be fixed as soon as possible!  Not exactly the reliable service I was expecting and the info is vague.  If anyone has any idea what the issue is and a ETA on a fix I would be most grateful.  Oddly I get full bar signal.....so it is not a signal issue.....and looking at the data returned from the handshake it seems my Smarty Sim is failing authorisation?  Thankfully I have access to wifi calling at home, however I would like to know what the issue is and when it will be resolved by.
