FAQ AT&T Samsung unlocking

It has been perfectly legal to unlock your cell phone ever since August 1, 2014, when President Barack Obama signed the Unlocking Consumer Choice and Wireless Competition Act into law.

Consumers have the right to unlock their phone and use it on any network in the world just by swapping the SIM card.

With an unlocked cell phone, you will be able to take advantage of the best deals on the market immediately and be in total control of how much you spent every month.

With doctorSIM, you will save time, money, and effort because you can request your unlock code online from the convenience of your home or office.

You will also be able to keep using your Samsung throughout the unlocking process.

Our method of unlocking via IMEI is the method recommended by the cell phone manufacturers and network operators themselves.

In addition, you’ll avoid the possibility of damaging your phone as it doesn’t require cables, software downloads or hardware alterations.

Yes, you can, however, unlocking your Samsung DOES NOT cancel the contract with your current network.

Even though you will be able to use your unlocked Samsung on any network in the world, you will still have to pay your monthly bills to AT&T until your contract expires or by paying an Early Termination Fee.

If your Samsung is under contract with AT&T, select our Premium Service directly rather than trying one of the other cell phone unlocking services first.

doctorSIM unlocks the cell phone's network so it can be used on any network as long as it prompts for the unlock code with a SIM card that isn't from AT&T.

If your Samsung has been reported by AT&T due to loss, theft or unpaid bill, the unlocking instructions we send you may not work until the issue has been resolved with them.

There is a possibility your unlocked Samsung will work outside of the US, but it is not guaranteed and doctorSIM will not be held liable if it doesn't.

Our Standard Service is a low-cost unlocking service with a reduced success rate that unlocks Samsung phones locked to AT&T but no longer under contract and with no outstanding bills.

Our Premium Service is a more advanced unlocking service with an almost 100% success rate for those Samsung phones which cannot be unlocked by our Standard Service. This service may be required if your cell phone has received technical support from Samsung, hasn’t been activated, is pre-pay or under contract.

Included in this service at no extra cost is a Defreeze code required for phones that have ‘frozen’ (hard locked) as a result of the incorrect code being inserted incorrectly too many times.

If you are unsure of the current status of your Samsung, select our Standard Service or contact our customer support team for assistance.

We will issue you a full refund if we are unable to unlock your cell phone with either unlocking service.

Yes, you do. One of the requirements to complete the unlocking process is to insert a SIM card from a different network i.e. not belonging to AT&T. Without another SIM card, the cell phone will not prompt for the unlock code and unlocking the phone won't be possible.

As completing the unlocking process only takes a couple of minutes, you can borrow one from a friend or family member if you haven't received your new SIM card.

It isn't necessary to know the exact model of your Samsung as the instructions on how to insert the unlock code are the same for all models.

The unlock code you receive will depend on the IMEI number (phone's unique identifier), so double check the IMEI number provided is correct by typing *#06# on the phone’s keypad.

However, if you need to know the exact model of your Samsung for any other reason, for example, to confirm the authenticity of a phone you want to buy second-hand, you can do so using our Identify Model phone check.
