Reach out to your mobile service provider and explain the situation. They may have specific processes in place to assist customers in recovering lost or deactivated numbers. They can provide you with guidance on the steps you need to take and the documentation required.
Verify your identity: Your mobile service provider may require you to verify your identity and provide proof of ownership of the previous number. This could involve providing personal information, such as your name, address, and any account details associated with the number.
Follow the provider's process: Once you have established contact with your mobile service provider, they will guide you through their specific recovery process. This may involve filling out forms, providing identification documents, or following any other procedures they have in place.
Reactivate the number: If your mobile service provider is able to verify your identity and confirm your ownership of the previous number, they may reactivate it for you. Once the number is active again, you can proceed with the WhatsApp verification process.
Verify your number on WhatsApp: Install the FM WhatsApp Apk on your device and go through the verification process. WhatsApp typically offers multiple verification options, such as SMS or call verification. If SMS verification is not possible due to the lost SIM card, you can choose the call verification option instead.
