Net10 Wireless is a Florida-based prepaid wireless phone service provider. A handful of cell phone manufactures, including Motorola, LG and Samsung, produce cell phone models which are branded for use on the Net10 network. When a cell phone is branded for use on a particular wireless network, it means that the phone has a network lock on it that restricts the use of the phone to a specific wireless network such as Net10. To use a Samsung Net10 phone on an alternate GSM wireless network, the phone's SIM-lock feature has to be unlocked.
