Andy said: "I haven't heard about it. I'm bad for not reading the news.
"I heard a few people's phones go off beforehand and people were speaking about it. Mine went off three minutes later.
"I think for the elderly generation it would maybe panic people a lot."
Anna added: "I knew about it through people at work. Mine hasn't gone off yet! I think everyone has got it at separate times. Maybe if there was a (real) alert it would come through at the same time."
