His tricks have seen him walk on water, defy gravity and pass through a glass window.
But, as his act went horribly wrong in front an audience of thousands, illusionist Dynamo found even magic can't help when you're faced with a poor mobile phone signal.
The magician, 33, failed to pull off one of his showpiece tricks while performing at London's O2 Arena - all because a call wouldn't go through.
In the show - also broadcast live on television on Wednesday - Dynamo, real name Steven Frayne, had just trapped the mobile phone of a volunteer called Tom in a bottle when things went wrong.
He asked an audience member to call the phone to prove it wasn't a fake, but nothing happened.
