I have an HTC One M9 for sale. Only been turned on once. Everything is perfectly fine on the phone, but I personally don't like the interface of an HTC phone so I would like to get rid of it.
Asking for $550. Retails at AT&T for $708.99.
Comes with box and original charger.
I can throw in a tempered glass screen protector too and if you want the phone to be unlocked I can get it unlocked for you, but I might have to ask for more depending on the cost for the unlock.
