Re: audiovox btr5600

How long have you owned your cell phone for? Also, did it act strange before it died on you? Let me know so we can get to the bottom of this. Thanks & good luck!

Phone does not start with sim card on it

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.

I had a similar problem with my SMT5600. I've found that when this happens, if I just hold the hangup key until the keypad locks, I can then unlock the phone and it will function normally. Try this to see if it helps.

Take care,

Audiovox smartphone stuck in Flight Mode

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.

Computer won't sync with audiovox smt 5600

You must install ActiveSync software on an Win XP OS available with disk supplied with phone or on MicroSoft support page.

If you are using Win Vista OS, then download latest Mobile Center software while you phone is plugged into USB port.

Phone must be recognized by OS for phone to charge. Nice Audiovox/Microsoft desigh heh? Some times you just want to get designs by the throat and squeeze them.

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.

SMT 5600 does not load OS, screen goes white and then blank.

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.

Audiovox smt5600 blinks amber light upon plugging in charger and wont charge and the (!)icon appears on the screen whichi n the manual means that the battery is either at too high or too low of operating...

Start with another battery. Borrow a friends or they are available on Ebay rather cheap. Or, go to your Cell Carrier and ask them to help you try another battery.

Have you tried charging it through the USB port of you computer? The phone is designed to charge from a USB port also, but computer must have ActiveSyn phone driver install and be recoginzed by the computer in order to charge using USB port.

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.

Computer fails to recognize smt5600

you can use any USB cable, there is nothing specific about any particular brand... now the computer has to recognize the phone. You need the software/driver.
