Question about Samsung SCH-u740 Cellular Phone

2 Answers

I bought a used Samsung SCH-U710 and it's asking for a code to unlock it. I can't do anything with this phone because I don't know the code. Can I get past this or erase it or something?

    I don't understand what you mean by compose. I tryed just dialing that code, but what then? When I hit send it says use restricted emergency call only.

  • jetsfaninohi Feb 02, 2010

    I keep getting asked for a code to get on my phone. I asked once how to skip or change the code to open it. I was given a code I was to compose, but I don't know what that means. How do I put that code in. If I try dialing it and hitting send it tells me restricted to emergency calls only. How do I put in the code or how do I get pass this?

What code is it asking??Is it a PUK or PIN(personal identification number) or NUC(network unlock code).

PERSONAL IDENTIFICATION NUMBER:

HI If you are asking for pin contact your service provider , he will give you a default pin .


If you try pin more than few predefined no of times your phone will ask PUK code which can also be given only by your service provider which is specific for each and every mobile number . Do not try PUK(new pin code) code many times or else your sim will be blocked and you will need a new sim.

Contact your sim customer care department over phone. Its free of cost to get the pin or puk no.

Go to the nearest service outlet of your service provider they can also help you.

There is no other go than the above procedure only your service provider can give it nobody else in this world nor any software.


PUK CODE:

PUK code can be given only by your service provider which is specific for each and every mobile number.
Contact your sim customer care department over phone. Its free of cost to get the pin or puk no. If you cant contact through your phone get some other phone and contact them.
Go to the nearest service outlet of your service provider they can also help you.
There is no other go than the above procedure only your service provider cangive it nobody else in this world nor any software.
Go to the below link and you can confirm that the above procedure works and there is a testimonial given by the customer too. http://www.fixya.com/support/t3582685-phome_lg_ke670_put_security_code_phone



NETWORK UNLOCK CODE:

You can unlock it by flashing your mobile if your mobile is a CDMA mobile...
The procedure for flashing your mobile is in the link below
http://hubpages.com/hub/How-to-Flash-your-cell-phone
It has an video explanation.


If your mobile is not an CDMA mobile , you can get the network unlock code(NUC) by just contacting the current network provider customer caredepartment.It is free of cost.

Therestrictioncode can be got from your old service provider..This restriction code iskept to prevent someone who stole themobile from using it with anotherprovider...

They will have a security check done with your date of birth etc..to verify whether you are the exact owner of the phone..

After that they will provide you the restriction code to unlock it and use it with another service provider..

It is all free of cost donot pay anyone for this seeing some advertisement over internet . That is all fake ads.

Of course your network provider didn't give that samsung sgh a887 unlock code except you still have a good standing account with them (in contract), but don't worry you can get samsung unlock code from third party sites. They usually sell a lot of models unlock code for any network provider. Good luck and have a try!

Forgot my unlock code to unlock phone


Hi, You may contact to your service provider Samsung SCH-U470 Unlock Code, they can open up all networks for you where you want to use your phone. Once your phone is unlock, it will work with any networks worldwide without sticking to one network only. I suggest to visit Samsung Unlock Code site, they will provide an accurate code with easy to follow instructions on how to unlock your phone.
Hope it helps.
Thanks.

Please i need help unlocking my SCh-R631 phone i tried to program it but it is saying that the unlock code is incorrect will you please help it also says initial programming is needed but it wont let me do...


You will have to reset your mobile phone back to factory default settings.

BUT FIRST.......................Look up in your phone manual for the code for your phone.
If you have not got it then you will have to get it off the net via the samsung website under ..............................samsung SCH-R631 unlock codes or samsung SCH-R631 factory default settings, you will need to remove your battery and make a note of your serial number and any codes on the reverse of the phone then replace the battery again.

Unlocking a samsung sch-r510 l


When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security Code then :-
This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (Security Code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone.
They should provide you with instructions on how to enter this code into the phone.
Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.

You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country. This may be a free service.
The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services. Use Google and search for "Security unlocking code” companies in your area.
You can also try this WEB site :-
http://www.mobileunlockguide.com/mobile-phone/
The IMEI number is unique the each mobile phone.
The number is printed on the label under the battery.
You can also get the IMEI number by entering this on your phone
*#06# It will then display your IMEI number and you may also get a unique global serial number. Your IMEI number should be 15 digits.
