1 Backup your data

Before you dispose of your mobile device, you should backup your data to a secure location, such as a cloud service, an external hard drive, or another device. This will ensure that you do not lose any important information, such as contacts, photos, documents, or messages. You should also sync your data with your online accounts, such as email, social media, or banking, so that you can access them from other devices.

2 Erase your data

After you backup your data, you should erase your data from your mobile device. This means deleting all your files, apps, settings, and accounts from the device. You should also remove any memory cards or SIM cards from the device. However, deleting your data is not enough to prevent data recovery. You should also perform a factory reset, which restores the device to its original state and wipes out any residual data. Depending on your device model and operating system, you may need to follow different steps to perform a factory reset. You can check the manufacturer's website or the device manual for instructions.

Encryption: If the device supports encryption, enable it before performing the factory reset. Encryption adds an extra layer of security to the data stored on the device. Verify Data Deletion: After the factory reset, double-check to ensure that no personal or sensitive data remains on the device. This may involve navigating through menus and settings to confirm a clean slate. Safely dispose of or securely wipe memory cards and SIM cards separately from the device. Remove Device from Accounts: If the device is associated with user accounts (e.g., Apple ID, Google account), unlink or remove it from these accounts. ....and something more...

3 Encrypt your data

Another way to protect your data from unauthorized access is to encrypt your data before you dispose of your mobile device. Encryption is a process that converts your data into a code that can only be read with a key or a password. If someone tries to access your data without the key or the password, they will only see gibberish. Encryption can be done at the device level or the file level. Some devices have built-in encryption features that you can enable in the settings. Alternatively, you can use third-party encryption software or apps to encrypt specific files or folders.

Educate Users about Encryption: Train your employees and users on the importance of encryption and how to properly use encryption tools. This awareness helps them make informed decisions about protecting their sensitive data. Implement Encryption Policies: Establish clear encryption policies within your organization, outlining the types of data that require encryption, the encryption methods to be used, and the key management practices.

4 Destroy your device

If you want to be extra cautious, you can destroy your device physically before you dispose of it. This will make it impossible for anyone to recover your data or use your device. However, you should be careful not to harm yourself or the environment when you destroy your device. Some methods of destroying your device include smashing it with a hammer, drilling holes in it, or burning it. You should also wear protective gloves and goggles and dispose of the remains in a safe manner.

5 Recycle your device

If you do not want to destroy your device, you can recycle it instead. Recycling your device is a responsible and eco-friendly way to dispose of it. Recycling your device can help reduce electronic waste, conserve natural resources, and prevent environmental pollution. However, you should only recycle your device with a reputable and certified recycler that follows proper data security and environmental standards. You can check the websites of your device manufacturer, your mobile carrier, or local authorities for information on how to recycle your device.

6 Donate your device

Another option to dispose of your mobile device is to donate it to someone who needs it. Donating your device can help someone who cannot afford a new device, such as a low-income person, a student, a senior, or a charity. Donating your device can also help reduce digital divide, promote digital inclusion, and support social causes. However, you should only donate your device after you backup, erase, encrypt, and reset your data. You should also check the condition and compatibility of your device before you donate it. You can find various organizations and programs that accept mobile device donations online or in your community.

To ensure proper and secure disposal of mobile devices (laptops, tablets, mobile phones etc) at the end of their lifecycle is: a. Maintain an accurate inventory of these mobile devices including owner of asset, serial no, end of life/end of support date etc. b. Notify the asset owner well in advance if the mobile device is about to reach EOL/EOS c. Determine the sensitivity of data stored in these mobile devices and accordingly backup and secure storage process to be determined. Use security solutions such as MDM, full disk encryption, 2FA, regular software updates etc d. When the device reaches end of life, ensure necessary backup taken and follow secure disposal process such as shredding, purging etc to ensure data can’t be recovered.

It is important to have proper endpoint and mobile device lifecycle process in place. For example, industry-accepted standards such as ISO 27001 have requirements for asset management, which includes mobile devices. It is important to keep an inventory of mobile devices, track their usage, and ensure proper disposal procedures are in place. There are multiple good MDM solutions, such as Microsoft Intune, which can be utilized to fill this requirement.
