I received a call yesterday while I was out running from a UK mobile number. My phone was in the key/ass pocket of my running shorts. I answered on my watch, but it defaulted to the handset instead of my headphones (ruddy apple devices). The call ended after about 10 secs. I fear this may have cost me dearly if it was Aer Lingus. Do they leave a voicemail if you don't answer? We have to keep our phones off while driving trains.
