App overview
Second Line — from Alloy Studios LLC — is a mobile app for iPhone and Android that provides a secondary phone number for making and receiving unlimited calls and SMS. Pick a local number from a large pool and use it like a traditional landline: reliable and available right on your device.
Compatibility and continuity
The app runs on most smartphones, and your numbers stay with you if you switch to a new phone. That means your contacts can keep reaching the same numbers even after you upgrade devices.
Quick start
Getting going is simple: enter your existing phone number into the app and begin using the service immediately. Texting is designed to be straightforward and user-friendly, and you won’t need to create a separate login to start messaging.
Main capabilities
- Choose a local number from a wide selection or leave the field blank and receive messages without assigning one.
- Make and receive unlimited voice calls and SMS using your assigned Second Line number.
- Send and receive texts directly with contacts who use Second Line or other phone numbers.
- Keep your numbers when changing devices so your message and call history remain reachable.
- Message friends, family, or business contacts without exposing your primary number.
Productivity and scheduling tools
The app also includes an automated messaging scheduler so you can compose messages in advance and have them sent at specified times — handy for reminders, appointments, or business communications.
Recommendation
If you’re looking for an extra phone line for personal or business use, Second Line (free version available) is a convenient option that combines local number selection, cross-device continuity, and easy texting/calling in one app.
