    I have a C139 Tracfone and the battery recently died.

    When I tried to charge it I got an "Invalid Battery" message.

    I tried another battery of the same type but I still keep getting an "Invalid Battery" message.

    Any help would be greatly appreciated!

You should be able to call your cell from a landline, then press either # or * then enter your PIN. Most cell services are that way.
Never it tried with tracfone, but it should work.

I suspect that we are talking at cross purposes. Each SIm has the facility to lock/unlock; that is a security feature. Airtime providers also lock their phones, though, and that - I fear - is what you have here.

Which country are you in and which Airtime provider's SIM have you purchased? Has the SIM been activated?

I have dealt with most UK Airtime providers, Vodafone in Italy, Greece and Cyprus, plus Movistar in Spain.

Sure. Use the Menu key to naivigate to the Settings Menu.
Go to the In-Call Setup and select it.
Under In-Call Timer go to Beep and turn it off!

SOURCE: setting up my voicemail on my Motorola C139 TracFone

Elementary, just as you would in any other phone, just dial your number, and the phone will talk you through on setting up your voicemail.

SOURCE: how to unlock the motorola c139

Press the "Menu" button and then the asterisk "*" in quick succession.

Pressing these same two buttons again will lock the phone.

(Note: the "Menu" button is the button in the center of the up, down, left, and right arrows. The asterisk "*" button is on the bottom left of the keypad.)

Phone dead

Here's something quick to try:

Have the battery tested to see if it holds a charge (This can easily be done by using an inexpensive multimeter). Place the multimeter leads on the battery terminals (red on plus, black on minus sign). Set the multimeter to DC voltage, 0-12 VDC. Let the phone charge for 4-6 hours with the battery in. Unplug the phone & take out the battery. Test the battery as explained above - if it isn't holding a charge...then the battery's probably bad (purchase another battery).

It sounds like your're stating that the phone works only when you plug it in, so I'm assuming that the power adapter and the plug recepticle are in working order - otherwise, the phone wouldn't work.
