Verify good signal strength

To check your signal strength
Touch

> Settings > About Phone > SIM status or Status > Signal Strength or Network Type and Strength
Check that your signal is in the target range between -87 dBm and -110 dBm. If your signal is below this, try moving to a better coverage area. If it's still too low, contact your mobile service provider to verify network connection.
