You can Hard Reset the phone by either of two methods. Start/Settings/Clear Memory, or power on while holding both left and right softkeys down.

This resets and reloads the phone software system its ROM and you will lose any and all personal data and apps you put on it since receiving it. Back up all you can before hard resetting.

Get an ATT/Cingular network SIM card for $6. It is a pay-as-you-GO phone SIM, but you can have ATT xfer your number to it and also make order a standard monthly contract plan for it.

If it is really an older ATT nework BLUE phone, then the new ATT Cingular network does not support it. It must be network unlocked to use on ANY carrier.

You can google the phone model and UNLOCK to get free unlock software you can use yourself on an XP PC . Software won;t run on VISTA.

Be sure you have SIM card in right. Look at contacts on SIM then allign them with SIM Contacts on the phone.

If this doesn't work, then SIM card itself is highly suspicious. Try it in another phone.

If phone was on ATT/Cingular originally, then you can buy UnLock code off ebay or net. If it is an older old BLUE ATT network, then the phone must be unlocked my using downloadable software you can use youself with an XP or earlier PC with an USB port. I don't know of any one selling unlock codes, based on phones IEMI code, that would work. Or at least get a guarantee if someone offers you this. If it is an ATT/Cingula or T-Mobile phone, then it can be unlocked using a code sent you base on IEMI number.

Google phones model and UNLOCK to find free downloadable software. This will also work on any HTC Typhoon phone, which the Audiovox SMT5600 is just one of many carriers that sold it.

Screen sound bad, or intermittent connection inside. You can find disassembly instructions on the net. Search with phone model and disassemble. Remove and reattach all cables in case one is lose or contact dirty.

I assume you mean the phone is asking for a network code or password before the Start Menu is available, ie, phone can be used.

If this is so and it is asking for a network code, then you need a SIM card that matches the carrier the phone was designed for. If it is ATT/Cingular, you can buy a SIM card from the new ATT/Cingular network for $6. It is a pay-as-you-GO phone SIM, but once you have it, you can call ATT to as for a number xfer as well as a standard monthly contract using this SIM.

If it is from the old Blue ATT network, then it cannot be used on ANY carrier unless it is unlocked for use on ALL carriers. This would be noted witht the docs that came with the camera. If nothing says ATT/Cingular, and especially if someithing says ATT without Cingular, then it is probably an old Blue ATT phone. You can buy a BLUE SIM off ebay which will get you to the point of being able to use the phones functions, but it will not work to make calls until you unlock it and replace the BLUE SIM with another current carriers SIM. Sprint will not work either because it is not a GSM ATT type network. Cingular and T-Mobile yes.

Google phones model number and UNLOCK and you will find a way to do it yourself at no charge if you have an XP or earlier PC with a USB port. Vista OS cannot be used to do it with the downloaded unlock software. It is also very hard to find anyone that can do it selling Unlock Codes based on phones IEMI code.

If it is not a network lock message, then it may be the last users personal lock password. In this case, you can hard reset the phone by holding down both right and left softkeys while powering on the phone.

Delete the headset from your phones previous or known devices and turn off phone then back on again and try pairing again. If still same could be faulty phone, but if you can try headset on somebody elses phone to rule out headset.

Hello, Wjmecca -

I hope I am correct in understanding you are referring to a smart phone. If so . . .

You will find the manual (PDF format) here:
Note: It is 154 pages long.

You will need Adobe Reader software (free) to download the manual, save it (to a computer file, which I recommend you name: Auidovox Smartphone, or something like it so you can find the document easily), and print it for easy reference.

If you do not know how to do that or if your AT&T GoPhone is your only access to the Internet, then seek the help of a relative or a good friend with Internet access, a computer, and a printer.

10^2 = 10 x 10 = 100
10700 + 4900 = 15600
100 x 15600 = 1,560,000
