1) it fluctuates to one bar to full bar erratically
2) frequent disconnections
3) people can't get me sometimes when that place is a common area with full line
4) like, when talking halfway can hear, cannot hear, can hear, etc.
5) most of the time my first phone call wouldn't get through and i have to call again..only 2nd time will go through..

boy, do i suck at describing but i hope u get my drift...

thanks!
