Unlocking an AT&T phone without a SIM card can be a bit tricky, but it is possible. Here are a few methods to consider:
Contact AT&T:
Contact AT&T customer service by phone or through their website.
Provide them with your phone’s IMEI number and proof of ownership.
AT&T will verify your information and send you instructions on how to unlock your phone without a SIM card.
Use a Third-Party Unlocking Service:
Search online for reputable third-party. One example of a third-party unlocking device is the unlock box.
Unlock boxes are devices that connect to the phone via USB and allow you to unlock the phone by providing a code.
This code is calculated based on the phone’s IMEI number and is unique to each phone.
Once the code is entered into the phone, it will be unlocked and will be able to be used with any carrier.
Some of the examples of well-know unlock boxes are “Z3X Samsung Pro”, “Octoplus” etc.
These devices are often used by professional phone repair technicians and phone unlocking service providers.
However, it’s important to note that using such devices requires technical knowledge and experience, and if not done properly, it can damage the phone’s software.
Provide them with your phone’s IMEI number and pay any necessary fees.
Follow the instructions provided by the service to unlock your phone.
Use a Software Unlock:
Research and find a reputable software unlocking tool.
Download and install the tool on your computer.
Connect your phone to the computer and follow the instructions provided by the software to unlock your phone.
Factory reset:
Go to the phone’s settings and select “Backup and Reset.”
Select “Factory Data Reset” and confirm the action. This will erase all data and settings on your phone, including the lock screen.
Use a Device Unlock App
How to check if the app is available on your device:
Some AT&T devices come with a pre-installed Device Unlock app. This app can be used to unlock the device without the need for a SIM card.
To check if the app is available on your device, go to the app drawer on your device and look for the Device Unlock app.
How to download and install the app:
If the Device Unlock app is not already installed on your your device and look for the Device Unlock app on play store or iOS to download.
How to use the app to unlock your device:
Once the app is open, it will prompt you to log in with your AT&T account. If you do not have an AT&T account, you will need to create one.
Once you are logged in, the app will check if your device is eligible for unlocking. If it is, the app will provide you with instructions on how to proceed with the unlocking process.
The process may include entering a code or connecting your device to a computer.
Follow the instructions carefully to ensure that the unlocking process is completed

How to provide the service with the necessary information:
Once you have found a reputable service, you will need to provide them with information about your device. This may include the device’s IMEI number, the carrier it is locked to, and your contact information.
The service may also require you to provide proof of ownership of the device.
How to unlock your device using the service:
After providing the service with the necessary information, they will send you instructions on how to proceed with the unlocking process.
The process may include entering a code or connecting your device to a computer.
