The connection is ok, i just need to go to the third floor to get a HSPDA signal or else it will be slower.

Modem traffic lights:
blue- HSPDA (fast)
green- EDGE (slow)

one more thing, just be careful on downloading(e.g. music,movies or files) or streaming in youtube because it will eat a lot of kilobytes. Always check your volume statistics to avoid extra charges.
