Question about Philips CD4451B/37 Phone

Open Question

Master pin on CD445/4, etc

I have recently purchased a CD445 phone set with 4 phones. A few days ago I entered some numbers (0870 and 0845) in the call barring mode but now find that I get constant engaged tones when calling other land-lines and people calling me also get the engaged tone. In short I cannot make or receve any calls. Even when I press the green button I do not get the normal dial tone, only the engaged tone, a regular single bleep.

I doubt it has anything to do with the call barring, but just in case, I have tried to remove it. However, each time I put in the defaut pin number 0000
I get "NOT POSSIBLE" come up on the screen. I am sure no-one else has put in a new pin No, and I have even tried all the normal variations I might have used if I had changed it myself and not made a note of it, all respond with the same, "not possible" reply. Please advise how I can get these phones working again and how I can ensure the pin number is returned to 0000.
My land line No is 0121-707-3443 which obviously will appear engaged & my mobile number is 07973-137965. I have an elderly father of 96 who regularly needs help, so it is vital that I have the phone working very quickly again.

Ido hope you can help me,

Ray Powell.

    When I turn on one of my cordless phones (CD 445) I just get 2 dull tones, and nothing else. I can't reset it, register it or do anything else, because I just get a "not possible" message, when I try.

Foget puk number


Few people use PIN locking system to lock their phone to avoid un-authorised access. Though this is a good option, it pisses you off sometime. Three wrong entry of PIN code will result in SIM blocking. Once SIM gets blocked, phone starts asking PUK code to enter. If you again enter wrong code for three times, SIM gets completely blocked. You have to walk into your service provider outlet to get a replacement SIM card. PUK code is a SIM specific code assigned by your service provider. No way you can guess & enter it. So, when it asks for the PUK code, don?t do anything, get the PUK code from your service provider. Airtel has a easier way of getting PUK code. For getting PUK code of a Airtel number, send PUKPhoneNumber to toll free number 121. You can make use of any other Airtel number to send this message since your SIM might have been blocked already. If the above method doesn?t works or your service provider is not Airtel, call to customer care using any other mobile phone which uses the same service provider. They will ask some details about you to make sure you are the owner of the SIM card. Questions might include your billing address, email ID, numbers you recently called or messaged etc. They might even ask you number printed on the SIM card, so be prepared with all details before calling them. Once you get the PUK code, enter it into the phone & your phone will return to normal.

I need help getting my unlock code.... please help me my imei code for my phone is 35191403312680/3 03 its a samsung behold~! email is ali_sina_west@live.com thanks


Hai,
**NOTE**:Please try not to disclose you imei number in public, its enough to provide your model number.

Try this:
Samsung Master Reset:
CAUTION: A "master reset" changes the phone settings back to default. This process will erase all contacts, downloaded settings, and downloaded applications (ringtones, wallpapers, graphics, etc). This process cannot be undone.

Enter *2767*3855# from the standby screen.
Hope this Helped!

call your new service provider and they will ask you a few questions to make sure it is the owner of the account.... then they will give you the pin number... i would suggest changing it to something you are familiar with the first time you access it.

Unlocking mobile phone


Hello Majaje68,
Have you tried entering the last four numbers of the phone number that phone had as the unlock code yet, that may be your SIM PIN. If that doesn't unlock it, you can try "0000", "1234". etc...
If you didn't apply a lock PIN, then it was probably done by your phone provider, in which case it's probably the last four digits of the phone number.
Good luck.

If it's the SIM Pin number to start your phone you've forgotten, keep entering any numbers, until the phone request the PUK number, available from your service provider.

If it's the phone Security number, I need the IMEI number to give you the Master Code, to reset your forgotten number.
