There are mini, micro, nano. Mini is what you have and what the BLU uses. My wife and her sister have the BLU and have moved over cards from flip phones. Mini is considered "standard" by me anyway.
I had to cut mine down to micro for my acer liquid SO phone but you should be fine with no cutting!!!!!!

Notice mini says most phones. Notice standard is 3" won't fit in most phones. Speakout people are rather amateurish as far as their products go.
