What Is a Second Line Phone Number?
Unlike traditional methods that required physical dual-SIM phones or carrying multiple devices, modern second line solutions work through software. This means you can manage multiple phone identities from a single device with complete functionality including:
- Making outbound calls
- Receiving inbound calls
- Sending and receiving text messages
- Voicemail management
- Call forwarding options
- Custom caller ID
