Pre Teen Phone Lines Need A Verizon Phone For Pre-teen (away For Summer)?

Need a verizon phone for pre-teen (away for summer)? - pre teen phone lines

Does anyone know a cell phone (Verizon) plan, which I block the entry numbers or any number of output blocks are allowed? I know that the Migo is in a position to score only 4 numbers - but we do not let the numbers for incoming calls as well?
