Motorola defy - i want to put a new sim card in, but i can only get emergency calls. Telsta said I need a pku number from motorola


PUK Locks or SIM Locks only come from the company that own the phone, usually the cellular provider when it was new. PUK Locks are also used when a phone is stolen so that the new user who bought it from a guy in a bar can't use it. Contracts are normally 2 years. The PUK lock is from the original company. This issue is NOTHING to do with Motorola. The company that had the phone originally as being difficult so that you can't use it, because they don't like losing your business and the phone they provided to you. They lock with a 128bit RSA encryption key at firmware level, which is the part of the phone that loads the data on the SIM and loads the Operating System. Plan B is to sticlk with Telstra, Plan C is get a new phone from another company.

Read this tip I wrote which fully explains

Your phone is asking for PUK code

and then I wrote this after a young lady who read the first one and then posted there must be another way to get past a PUK Lock.

So your phone asks for PUK Code and you ask if there is another way

Once you have got it unlocked, take it a kiosk or shop of the new company and let them put the new service on it. They need control of the phone physically to make it theirs via IMEI number.

Entered wrong pin code and now my telstra ZTE F156 is blocked and i need the PUK code,but it says 'phone blocked try after 12 hours.PLEASE HELP!!


These directions are for an AT and T phone, but other than that, are the same for any carrier. A PUK (PIN Unlock Key) code is required to unlock SIM cards that have become locked following three successive incorrect PIN entries. If your SIM card becomes locked, you will need to get a PUK code from your phone carrier to unlock your SIM card. You can obtain your phone's PUK code from your carrier in one of these ways: Log in to Your account.online Use a Technical Support Chat Contact your carriers Customer Care Get Your Phone's PUK Code Online Go to the Phone/Device page. From the My Phone/Device screen, select the Unblock SIM Card link under the My Make & Model heading. The Unblock SIM screen will display your PUK code and will give you instructions for unblocking your SIM Card. Once you receive your PUK code, you will need to enter it into your phone to set a new PIN code. Note: If you enter the wrong PUK code 10 times in a row, your SIM card will be invalidated, and you will need to purchase a new SIM Card. The phone will display the following error: "PUK blocked call operator

Tocco lite phone freeze deactivate fail


here is some info on PUK codes:

try taking battery and SIM out waiting 15 seconds and powering cell back on.

In your case I believe your SIM is now FROZEN or locked. You mostlikely will need to purchase a new SIM card.

A PUK code (Pin Unlock Key) is required when you enter an incorrect PIN 3 times. After entering the wrong PIN 3 times, the card will be locked and you will need to get a PUK code from your service provider to unlock it.

If the wrong PUK code is entered ten times in a row, the SIM card becomes invalid and you will need to purchase a new SIM Card. The phone will display "PUK blocked call operator".

I have 3 sim card and pt i inthe telstra lg tu550 when I turn it on it PUK BLOCKED


I assume that your Telstra LG TU550 IS UNLOCKED AND NOT NETWORK RESTRICTED. Your SIM card could be locked due to wrongly enteriing your pass key wrong at least 3 times: DO NOT ATTEMPT TO enter the wrong pass key again as after 10 total attempts, the SIM WILL SELF DESTRUCT and will need to be physically replaced at a cost. Solution: Contact your sevice provider for the SIM and get them to give you the Phone Unlock Key (PUK) associated with your SIM (you will need to prove you are the registred owner of that SIM card and Mobile number). Alternatively, if you have registred the SIM online, the PUK code is either already available online or can be requested online. Hope it helps and let me know how you go.

Need a PUK code for a telstra prepaid sim .a hand me down we dont know the password needed for telstra to supply puk. any ideas??


Pin codes and PUK codes are meant to protect the sims.

If you wrongly put PIN Codes a number of times, to really protect your sim it will ask you a puck code. (Please note every sim has its unique PUCK Code.)

Pincode/Puck codes for any sim are provided by the service provider. (In your case, Telstra an Australian SP).

You may require to contact your Service Provider Network and speak to Customer Service Representative for getting this information (PUK code).

Kindly dont apply any more codes any further or otherwise the sim may get permanently blocked and you may have to replace it.

Please rate this support if you find it useful.
