I thought I read some time ago on these boards, that if you request the wake-up call on the hour, quarter hour, half hour, etc. it might not always work because so many people have requested that time that they system bogs down and not everyone gets the message. So I requested an odd time, like 5:37 a.m. and we got the message every day. It did take a few seconds before it came on, but we always got it. Now I don't know if this is true or not

but it's worth a try.
