Using Call Block
If you subscribe to Caller ID, you can save phone numbers to the call block list. When a call comes in, the phone compares the received phone number to the numbers on the call block list. If the phone number is on the list, the phone replaces the caller's name with Call Blocked and disconnects the call. (The caller hears a reject tone.)

The call block list holds 20 entries, and all stations share the same list. You can add entries through the Call Blocking menu, by selecting Add Call Block in the CID menu, or by blocking incoming calls. (Only one station can edit the call block list at a time.)

Blocking incoming calls

1. When the phone rings, wait until the display shows the Caller ID information (usually after the second ring).
2. If you want to block the call and add this number to the call block list, press Block.
3. When the phone asks you to confirm, press Menu/select or Block. Blocking an incoming call from an "Unknown" or "Private" number is the same as selecting Unknown Number or Private Number from the Call Blocking menu.

Call Blocking menu options

1. With the phone in standby, open the menu and select Call Blocking.
2. Choose one of these options:

• Create New(Handset only) - Add an entry to your call block list. The phone will prompt you to enter a name & phone number.
• Private Number(Handset only) - Block all calls from numbers reported by CID as "Private." (This does not count as one of the 20 entries.)
• Unknown Number(Handset only) - Block all calls from numbers reported by CID as "Unknown". (This does not count as one of the 20 entries.)

Call block entry options

1. With the phone in standby, open the call block list and find the entry you want.
2. Press Menu/select to open the individual entry menu. Choose one of these options:

• Edit(Handset only) - Edit this entry. The phone will prompt you to edit the name & phone number.
• Delete - Erase this entry from the list & allow calls from this number.

You need to get a PUK, PUKs, or personal unblocking keys, are used to unblock a mobile phone which becomes blocked. Mobile phones may become blocked when a PIN (personal identification number) is entered incorrectly on three consecutive occasions. In some instances, the phone may become blocked, which requires a PUK to unblock it, and in other instances, the SIM (Subscriber Identity Module) card itself becomes blocked and again will require a PUK to unblock it. Mobile phones are also blocked when they are reported stolen and if there is an outstanding payment on the account. It is important to differentiate between unblocking phones (using a PUK) and unlocking mobile phones (using another type of code). More information on unlocking phones will be available here in the very near future. NOTE: It is a criminal offence for anyone to attempt to unblock a mobile phone, other than the network provider who put the block on the phone. If your phone has become blocked by mistake, for example you have entered the PIN incorrectly on three consecutive occasions, then you need to contact the mobile phone network operator with your details. To explain a little more, specific to your mobile phone network, use the links above to navigate your way to the specific PUK details for your mobile phone network operator.

if you want to block your own number dial *67 before you dial... to block someone else try dialing

To activate Call Block or add a telephone number to the rejection list, dial *60. If you dont know the number to be blocked, dial *60 immediately after hanging up from the call. To turn off Call Block, dial *80. Call Block cannot block calls from some cellular phones, pay phones or business lines. It also cannot block most long distance numbers.

hope this helps...please rate...thanks

Unfortunately, Sprint does not have the ability to block single numbers from calling you. We can either block all incoming calls, all outgoing calls, or both, but not particular numbers.
