There are a few reasons why you might not be able to deactivate your messenger. For one, your phone may not be compatible with the messaging service. Additionally, if you have a subscription to a messaging service like WhatsApp or Facebook Messenger, then those services may still be active even if your phone is off. Finally, if you’re using an app like Signal that uses Bluetooth to communicate, then your phone may not be able to connect and activate the messaging service.
