Description
The UK conducts its first test of a new emergency alert service on Sunday April 23, with millions of mobile phones emitting a loud alarm and vibrating. The alert was due to go off at 3:00 pm (1400 GMT) but some some, like Suzanna Hall, seem to have never received it: "Everyone's phones were going off, but mine wasn't. (...) I don't think everyone's managed to get it." IMAGES AND SOUNDBITES
