Released for T-Mobile, the Samsung SGH-T409 is an easy-to-use flip phone with a host of features, including Wi-Fi connectivity, Bluetooth wireless technology, a built-in 1.3-megapixel camera with digital zoom and picture and ringer caller ID. Available in a sky blue color, the SGH-T409 seamlessly makes and receives calls over a home Wi-Fi network with T-Mobile HotSpot @Home. While at home, customers can enjoy mobile coverage and unlimited domestic calling over Wi-Fi; while mobile, customers also can get the same benefits at all the nearly 8,500 T-Mobile HotSpot locations across the country. In addition, unlike with VoIP calling, when T-Mobile HotSpot @Home customers leave home or exit a T-Mobile HotSpot, their calls will transfer onto T-Mobile's GSM/GPRS/EDGE wireless network, giving people the freedom to continue their important conversations uninterrupted as they go about their day. Calls also transfer from T-Mobile's network onto Wi-Fi.
