I work in a building that makes even my VZW service drop to no signal. Occasionally it will regain weak reception but eventually drop out again completely. I've had a couple people try to call me during the times of no reception. Unless they leave a voicemail I have no idea they tried to call - no missed call notification. I really need to know when I miss a call. I have wifi access. Would Google Voice be a good bandaid? I am using a android device.
