Antenna Obstruction
The antenna is on the top-right corner on the back of the device. Make sure no metal is covering it when calling.

If airplane mode is off and you still have no reception in a serviceable area, check your SIM card and make sure it's fully inserted. The phone should give a message that no SIM card is installed.

If the problem is not fixed, you might want to replace the antenna.
