On the topic of blocked caller,
If I blocked a number and delete it from the phone.
Does it mean that the caller will be permanently blocked from contacting my number?
Later if I don't want my number and it goes to a new user.
Will the caller number be be still blocked from contacting the new user?
When there is a number, we can use the phone to block. When the number is private it will still go through. So rather than rely entirely from blocking, might I suggest you use an app, such as 'Showcaller', that have a world wide database which you can contribute, do checking, etc etc. Nowadays there are too many telemarketers and they are such an annoyance. By using this app, all those unknown can be checked whether is spam or telemarketers or genuine. So when these 'people' calls, the caller id will have extra info if the number already reported to the database. So you can chose not to answer.
BTW blocking is specific to your phone and not your account/carrier. If you do sell your phone, just do a full reset to clear away all those info. Also if you do not use or access your voicemail, might as well you disable it, I have noticed that calling own voicemail is extra cost (maxis).
