There are cell phone shops that provide unlocking services for a nominal fee. There is unlocking software that will allow you to possibly unlock your phone using your PC. The shops that provide the service should/will guarantee success in unlocking them though.

If you want to do it yourself? Let us know and we can direct you to such software (though these softwares usually come with disclaimers stating that they could damage your phone, though if the instructions are followed to a T haven't damaged any phones that I am aware of).

Samsung sgh d407 asking for sim lock


If your Samsung is SIM locked then you need to unlock it. You can unlock it using codes. Unlock codes are provided by the network provider or online providers. Network providers may take a long time to give the code. At that case you can contact online providers like Mobile-Unlocker.com who give the codes quickly.

My audiovox smt 5600 can't show start any more if any one can help me restart it with a code pls mail me at temitope.4all@yahoo.com


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.

Unlock my blackberry 7290


Like you being with T-mobile, I bought a cingular phone off ebay that wasn't unlock. My sims didn't work either. My network just said call Cingular which is now AT&T and they gave me the MEP code to unlock it. Beware, you need to confirm all of your information from your network before they will help you.

First need to find the IMEI for your phone. Power on phone and type *#06# this will display the IMEI. You will need the IMEI to get the corresponding unlock code. Every phone has a different unlock code. Then call your provider and request the unlock code.

Sony Ericsson - General

Action
1
Insert non-Cingular SIM card
2
Power on the handset
3
Press the left Arrow (<) button
4
Press the star (*) button twice
5
Press the left Arrow (<) button

- display will indicate "ME Lock"

- wait approximately 3 seconds

- the display will indicate "Network" and a picture of a closed lock
6
Press Yes

- the display will indicate "Unlock?"
7
Press Yes

- the display will indicate "Enter NCK"
8
Enter the SIM Unlock code
9
Press Yes

The handset will display "Network" and a picture of an open lock for three seconds and will then revert to the main display.

The handset is then successfully unlocked.
