Looking at buying MX key
 

Hi

As the title suggests, I am looking at buy MX key.

So far I have MTbox, jaf and advancebb5

I generally only use MTbox at the moment - That is what im looking at purchasing mx key.

1) So are all the models free to unlock? Or is there some kind of activation involved?

2) Also mx key is just a dongle? and I use jaf box + fbus cables to connect phones? using mobileEx software?

3) Can anyone compare MT-box vs mx key (if you have both)

Sorry about all the dumb questions - Just got a bit confused with this link saying 'free credits'
