Apple Music are currently offering a 3 month free trial on their music streaming service, provided you have not signed up previously. While this is not as good as the EE free 6 month deal, if you're not on that network, this isn't a bad alternative.
I haven't signed up to the service yet, as still using a free trial with Google Music, but this is next on my list to move too, when the Google free trial expires shortly.
While all these companies offer free trials, I'll just keep switching between them, until they stop.
Just a word of advise, remember to cancel before the end of the trial or you will usually be automatically billed to the credit card you have to register when signing up, for the following month after the trial ends, which is £9.99 a month... Some services let you cancel a subscription at any time during the trial and can continue right till the end of the free period and others cancel your trial immediately, not sure what Apples policy is here(?)...
I've previously used Deezer, Spotify and Google Music, and think Deezer is my favourite. But they are all pretty good and every one has their own preferences.
Apple Music offers an Android App, so is open to users of both Google and Apple phones!
