CAUTION WITH MOBILE PHONE / SMARTPHONE

CAUTION WITH MOBILE PHONE / SMARTPHONE
On July 21st, 2017 we drove from Dublin to Holyhead with the Epsilon.
On arrival in Holyhead, an SMS arrived that the 10 are less on both accounts. Debited from a Norwegian company / maritime network. Called the port (ship was just leaving) for the M50 toll and my son had surfed the internet. The notification SMS came 2 hours after the ship left.
The maritime network should normally be switched off within the 12 mile zone.

SO: BEFORE GOING ON THE FERRY TURN OFF YOUR MOBILE PHONE.
