The mobile phone firm has announced that they will be partnering with the Worthy Farm festival held in Somerset between June 26 and June 30 for the sixth time.
This year, Festival-goers will be highly-connected at the world's first 5G-powered festival.
With 5G phones not widely available as of yet, music fans will be able to have access to the high speed service via 5G-powered WiFi.
Glastonbury's co-ogranser Emily Eavis - who along with her father Michael Eavis booked The Killers, The Cure and Stormzy to headline this year's festival - said: "We're extremely pleased to have EE back again, providing the best possible network for our rural site. And it's great that we're going to be one of the first places in the UK to offer 5G."
As well as the 5G service, EE will have phone charging and power bar swapping at their EE Recharge Tent.
All is required is the purchase of a Juice Tube Power Bar for £20 to get one full charge, which can be swapped once a day.
