Wireless Emergency Alerts

This device is capable of receiving optional alerts from local, state and national emergency management officials. Wireless Emergency Alerts (WEA), also known as Commercial Mobile Alert System or CMAS, is a national alert system that enables rapid dissemination of warnings and safety information via text alerts to wireless phones based on their geographic location. The Federal Emergency Management Agency (FEMA) is responsible for receiving the safety information and forwarding the alerts to participating wireless carriers such as Sprint. Alerts can come from the President of the United States, the National Weather Service (NWS) or state and local emergency operations centers. This system is integrated with the national alert system that serves television and radio stations today.

2.0 out of 5 stars Poor Quality April 30, 2013
I had a Sony flip phone since many years with satisfaction. Its battery became bad and I couldn't find any battery replacement.
I bought this Samsung M400 phone because I wanted a "non-smart" flip phone.

- Good reception,
- Good battery,
- Speaker is OK,

- Voice Command button on the left side is bothering and there is no way to deactivate it.
- Voice recognition is really bad. It is practically not usable.
- Display font size is not changeable.
- There is no place for SD card or other memory cards. You can not increase the memory.
- There is no driver for USB connection. You can't transfer photos to your computer, except you send it via email.

I wouldn't recommend this phone to anybody.

2.0 out of 5 stars Nonstop problems June 14, 2013
My husband and I both got this phone as our upgrade recently. We use our phones only for talking, and need only the most basic features.

Within two months, his phone stopped holding a charge. Unless it was actually on the charger it would not power up. He had to get a new battery from Sprint, and within a week of getting it, started having the same problem again.

My own phone began doing the same thing within days of activation. A trip back to the store resulted in upgrading my settings, but did not solve the problem. As of today we are still without working phones and are about to make our third trip to Sprint.

I'm tempted to believe that phone manufacturers are so busy cranking out smartphones that do everything but wipe your butt for you and cost a fortune, nobody can be bothered to make a reliable, basic phone with quality hardware. Very frustrated and do not recommend this model.

1.0 out of 5 stars Can not disable dedicated 911 button. July 1, 2013
Basic flip phone, but has extremely annoying dedicated 911 button. I can dial 9-1-1, I don't need or want one button solution that can be pressed by accident. I can not fathom why they do not have the ability to disable it.

Kinda pricey for basic phone too. As another reviewer noted, why can't they just sell a reliable basic phone?
