Well Dad is back in communication as he has a new mobile phone - a tenner from Tesco. Thanks to Asda all the credit from the lost/stolen phone has been transferred to his new phone as well as his original phone number. So if you've got Dad's mobile number drop him a text as he's lost all his contacts!
He had a bit of a learning curve and almost gave upon texting for good as couldn't get it to work. He said it had a mind of it's own and it was using the phonetic alphabet! Since found out what he meant was I'd left predictive text on !
