Siemens SX 56 ATT Wireless phone - Need help to unlock it
I have this phone for the past 6 years but have not been able to use it since ATT went thru the mergers. I am novice and am looking for your guidance and advice. I did go thru the XDA website and thought the process to be extremely geeky and risky. Hence this request. I have an international (Europe and Asia) travel coming up towards the end of this week and was hoping to be able to use this phone. I do have the cradle for the phone but donot have the USB sync cable. I would really appreciate if soneone could help me to get this resolved at the earliest. I am providing you with the hardware details that I thought would be of help.

Call AT&T (611 from your device), tell them you're going overseas and that you'd like you're unlock code. Once you get it, follow these steps:
1) Have phone on with AT&T SIM inserted
2) Turn off all Wireless options (including the phone signal)
3) Go to Options-Advanced Options-SIM
4) Type Alt+MEPD (nothing will happen)
5) Type Alt+MEP2
6) A box should pop up asking for your unlock code.
7) Enter your code here and hit enter.
8) Reboot phone
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.
As I understand it, the SIM card is what tells your wireless unit which service provider to use. If you have an old phone, it should be an easy matter to take the t-mobile SIM card out of it and install it in the SX-66. One note on the SX-66: the SIM card on mine had a tendency to lose contact (and my contacts would disappear) from jarring until I put a piece of scotch tape across the bottom of it. No problems after that.
