All you have to do is text XBOX to 150 and you'll have a 30-day rolling contract. This means you can cancel the add-on at any time if you're not happy with it, or find a better Game Pass Ultimate deal out in the world.
While the details are slightly hazy, it appears the unlimited gaming you get is the same as EE's Gamer data pass. The somewhat confusing factor here is that the Xbox Game Pass app isn't included there, like it is with this offer.
That means it appears you'll get unlimited use of Twitch, Pokemon Go, Harry Potter: Wizards Unite, Star Wars: Galaxy of Heroes and Fifa Mobile. You can also add a controller for your phone as an additional £7 a month when buying a new phone or SIM plan from EE.

Whether you're an EE existing customer or someone who is looking to sign up, this will be an excellent add-on. Xbox Game Pass Ultimate normally costs £10.99 a month. That makes this 99p a month cheaper than going directly through Xbox, plus EE will throw in the unlimited gaming too!
EE's Samsung Galaxy S21 deal + Xbox Game Pass:
EE does have an alternative way for you to get an Xbox Game Pass Ultimate subscription. If you sign up to a number of Samsung phone deals, you'll get a year of the gaming subscription for free.
However, with this offer you don't get the unlimited gaming part of the promotion and you'll have to order before June 1 to get this deal. We've listed the devices you can do this with below.
