Secret Garden Party is one of several festivals this year offering tickets straight to your mobile.
The revolutionary system, called Tixmob, allows festival goers to wait until the last minute to buy tickets.
With the weather proving such a problem this year, it gives music fans more time to make up their mind.
Festival organisers have been endorsing Tixmob, claiming it to be a more environmentally friendly exchange as it rules out any need for paper.
Freddie Fellowes of Secret Garden Party said: "The Great British summer wash out isn't enough to dampen our spirits, or our site for that matter, but for anybody hedging their bets last minute tickets from tixmob is by far the easiest way to secure a ticket to this unique event."
Tickets for the Cambridgeshire event, being held in from 26-29 July, are available right up until the start of the event with tickets delivered direct to your mobile for immediate entry.
There is a 2 per cent commission charge and no delivery fees, making Tixmob the cheapest way to buy festival tickets in the UK.
Other festivals signed up for the new service include 2000 Trees, Bloom, Belladrum and Big Green Gathering.
Acts playing Secret Garden Party include Alabama 3, Sunshine Underground, New Young Pony Club, Reverend And The Makers and Echo And The Bunnymen.
To buy tickets fans simply log on to new mobile ticketing website www.tixmob.com and pay for their tickets using a credit or debit card and have them delivered immediately to their mobile phone.
You can even choose to receive all tickets on one phone or have them sent to others.
Ramesh Kumar, business development director, Tixmob, added: "Having fun shouldn't be hard work so we set up tixmob to provide easy, reliable and affordable access to gigs and events. We redeem more tickets than any other company in the world so this is an obvious next step for us."
