hi i have a 3g zte k3806z stick...but it doesnt work on my arnova 10 g2...the stick is turn on..but it doesnt fix the signal...the range doesnt appear.

I disabled the pin of my stick but i dont know how can i turn off the memory and autorun of this stick...anybody can help me?

btw:in my area the signal is good, is always umts or hsdpa so there is no problem with switch from 3g to 2g...
