I need to chang my access code number on my TGC 350 phone. The one I put in doesn't work.

Panasonic has the manual for the KX-TGC223ALS on the product site: http://www.panasonic.com/au/consumer/household/cordless-phones/phone-with-answering-machine/kx-tgc223als.html . The direct link to the manual is http://www.panasonic.com/content/dam/pim/au/en/KX/KX-TGC/KX-TGC223AL/TGC220_TGC222_TGC223.pdf . The final digit in the model number indicates the number of handsets that come with the phone in the original package.

I hope this helps.

The D1680 doesn't come with a security code so you must have entered one. You can change the security code following the instructions on page 15 of the manual. You'll need to be at the phone, so you can't do this remotely.

If you mean the PIN for remote access, that's a two-digit number. If you've forgotten what it is, you can change it at the base station by following the instructions on page 12 of the manual.

If you mean the messages on your telephone company's voicemail system, try dialing *67 (that's star-six-seven). If that doesn't work, contact your telephone company for instructions on accessing their voicemail system.

need to un lock network for any sim card

Hi if you give me the phones imei number i can then use the software i have and give you your master code how ever you need to know the following.

1 if you have entered the wrong code more than 5 times then the phone may be hardlocked and can only be unlocked using leads and software.
2 i will check if the phone has been reported .lost or stolen and if it has i wont be able to give you the code.
3 if your phone has the latest firmware then the master code may not work as nokia changed it to stop people unlocking them if they was lost or stolen.

you can find your imei number by looking on the back of the phone under the battery it will look something like this
8944124/1244/1244

give or take a few numbers ok

once i have this i will generate your master unlock code and this will then give you full access to the phone and it will remove the security code until you need to put another one on the phone the master code resets the code to what it was when new usually 1234 or 0000 should you ever need to put another code on the phone.

let me know then i can assist you further ok

Your phone’s four-digit unlock code is originally set to 1234 or to the last four digits of your phone number.
The six-digit security code is originally set to 000000.
Your service provider may reset these codes before you get your phone.
If your service provider didn’t change these codes, you should change them to prevent others from accessing your personal information. The unlock code must contain four digits. The security code must contain six digits.
To change a code or password:
Find it: Settings > Security > New Passwords
You can also change your SIM PIN codes or callbarring password.
Select the type of code you want to change, enter the old code when prompted, and then enter the new code.
If you forget your unlock code: At the Enter Unlock Code: prompt, try entering 1234 or the last four digits of your phone number. If that doesn’t work, contact your service provider.
If you forget other codes: If you forget your security code, SIM PIN code, PIN2 code, or call barring password, contact your service provider.

The security code (5 to 10 digits) helps to protect your phone against unauthorized use. The preset code is 12345 provided you or someone else have not changed it. You can change the code and set the phone to request the code by selecting menu>settings>security>access code.
Should in case the default code 12345 does not work, it means it has been changed by you or someone and you can only access the phone by putting the new code or use the imei number behind the phone battery to unlock it. This can only be done by mobile phone technician or you can visit the web to find out if you can do it for free.

try the last 4 digits of your mobile telephone number

sir the plus sign indicates the local international access code... no need to insert it while callin.. if your phone service includes international dialing press and hold 0 to insert local international access code(indicated by + ).then press keypads to dial country code and phone no.. this will surely work... dont forget to rate me.. thank you sir.
