I want to block a number from my Doro easyphone 615

SOURCE: need to be able to block a certain number from calling on a w385 phone

Motorolas are my pet hates, the phone's menu layout is NAFF. But I'll try to give you a general idea, whether it works on Motorola or not I don't know for sure.
Place his number under a specified group, especially for the people you don't want calls from, then select only the groups that are allowed to call you. This works on the best mobile phones, IE. Nokia.

Hi
some Samsungs have a 'block list'. I am quite sure that the D900 has it. All you have to do is when you receive a text from this number select options, and you should see in sub menu 'add to block list'. I am not sure if it also blocks calls once added to the list? Hope that helps?
