"I've seen it a few times. It's not a big trend but it is going on. I've seen people buried with all kinds of things, even a pager," he said.

"Some other people may be terrified they'll wake up in the coffin, so they take along a mobile to ring for help to get them out," he said. However, certain rules would apply, including making sure the mobile is switched off or on silent before it accompanies the deceased.
