The two-minute viral video features lookalikes in the roles of members of the royal family including Prince William and his fiancée Kate Middleton. The couple will tie the knot on April 29 at Westminster Abbey.
Also making appearances are the Queen, Prince Charles and Camilla, Duchess of Cornwall, Princess Anne and Prince Andrew.
The clip has received a mixed reaction, with some fans criticising the mobile company for bringing "out another parody" instead of an "original" flash-mob video in a similar vein to its previous advertisements.
However, another viewer commented: "I'd rather take two minutes watching this video then two hours watching the actual wedding."
