Product Performance
Getting the Most Out of Your Signal Reception
The quality of each call you make or receive depends on the
signal strength in your area. Your phone informs you of the
current signal strength by displaying a number of bars next to the
signal strength icon. The more bars displayed, the stronger the
signal.
If you're inside a building, being near a window may give you
better reception.
