Trick or treat? You decide

As the UK’s kids (and big kids) prepare to don their best outfits and set of in the search for treats to ward off the evil spirits of Halloween, we thought we’d indulge in a little trick or treat action of our own.

The treat is a chance to win a Samsung Galaxy Alpha – their most beautiful smartphone to date – in fact, you could win one each for you and your friend. The trick? Well, you’ll just have to wait and see.

To nominate your mate for a trick or treat, tweet us @O2 using the hashtag #O2possessed and remember to include your friend in the tweet. Tell us if you want to trick them or treat them, and let us know why you’ve nominated them.

Be warned, though – you may not get what you’ve asked for. With only one prize treat, you may find yourself tricked if you’re not the lucky winner. Whatever you request – trick or treat – we’ll enter you into the competition to win a pair of phones for you and your pal.

Entries close at 11:59pm on Wednesday 29 October and we’ll pick our winning pair on Thursday 30 October. We’ll notify the winner by DM, so make sure you’re following us before you enter. For terms and conditions, click here.

Don’t forget – this isn’t the only chance you’ve got to win a Galaxy Alpha with #O2possessed. Try your hand at ghost hunting from 1pm today to be in with another shot.
