2ndLine - Second Phone Number for Android

Quick summary

2ndLine — branded as Second Phone Number — is a mobile VoIP app from TextNow, Inc. that gives your device an extra phone number. It’s designed so you can separate work-related calls and messages from personal ones without buying a second SIM card or a separate device.

How it works

The app runs over Wi‑Fi or your cellular data connection and operates like a regular phone line: you can place and receive calls and send texts using the additional number. Because it uses internet transport instead of a cellular voice plan, calls and messages to recipients in the United States and Canada are effectively free; international dialing is supported at low rates.

Main features

• Make inexpensive international calls and receive voicemail (with optional transcription).
• Send images, GIFs, stickers and emoji in chats.
• Forward incoming calls and set a custom caller ID.
• Use group messaging and add custom signatures to your texts.

Extra conveniences and personalization

• Assign unique ringtones and background images to specific contacts to help distinguish callers.
• Protect access with a passcode and integrate with Google Smart Lock for easier sign‑ins.
• Quick Reply: respond from a pop‑up notification without opening the full app.
• A single unified inbox: messages for both your primary and second numbers appear together for simpler management.

Availability and cost

2ndLine works for users located in the United States and Canada only; accounts cannot currently be created from other countries. Within that region, standard calling and texting to U.S./Canadian numbers is free when you’re online, so your only ongoing cost is your internet connection. International destinations incur modest per‑minute charges. A paid tier is available that unlocks additional features and removes ads.

Pros and cons

Pros:

• Lets you add a functional second number without changing hardware or plans.
• Generous messaging features (media, GIFs, group messages).

Cons:

• Restricted to U.S. and Canada for sign‑ups.
• Some users report occasional login or connectivity issues.

Bottom line

If you need a separate line for business or temporary projects and you’re in the U.S. or Canada, 2ndLine offers a convenient, low‑cost alternative to adding a second SIM or phone. Its customization and messaging tools make it worth trying—consider the premium option if you want an ad‑free, enhanced experience.
