Released in 2008, the Samsung J700 features the classic slide phone design, a 2-inch colour display, SMS support, an FM radio and a 10 MB internal memory card. Additionally, the Samsung J700 allows you to block text or media messages and calls from certain phone numbers. Although the process of blocking a call might not seem intuitive, it's fairly simple and only takes a few moments to complete.
Dial the number you would like to block into the keypad as though you were calling the number.
Press the "Options" button.
Highlight the "Save" button and press "Select."
Highlight the "Block Number" item in the list and press the "Select" button.
