Using Signal on a cloud phone
Signal registration is tied to a phone number that can receive an SMS or phone call. Signal permits one registered mobile device for an account at a time, so placing the account on a cloud phone requires planning. Before regular use, verify registration, permissions, message delivery, calls, notifications and any linked-device workflow you depend on.
Recommended Signal verification workflow
Install Signal from its official store listing and use a phone number you control that can receive the verification SMS or call. Never share the verification code. After registration, verify sending and receiving messages, attachments, camera and microphone access, voice and video calls, notifications after the app has been idle and any required linked devices. Plan account transfer or re-registration carefully before changing an important setup.
Protect the registration and account
Signal's documentation says an account can be registered on only one mobile device at a time, although supported secondary devices can be linked. Moving the mobile registration may therefore affect an existing phone. Keep the device, registration code and account secure. Do not use CloudPhoneIO for impermissible bulk or automated messaging, unauthorized account creation, unauthorized access or collection of other users' data.
