2ndLine - Second Phone Number

Get a second line with free US and Canada calling

2ndLine gives you a dedicated phone number you can use for work, side gigs, or online listings, without needing a second SIM slot. It routes calls and messages over WiFi or mobile data, so you are not drawing from your carrier minutes. Calling and texting are free within the United States and Canada, and your contacts do not need to install the app to reach you. If you call abroad, rates are positioned as low cost, which makes occasional international outreach practical.

Beyond the basics, messaging feels complete. You can send photos, emojis, stickers, and GIFs, start group conversations, and even append signatures to texts. Voice features are equally robust: you get voicemail with transcriptions, call forwarding, and the ability to set a caller ID. Security and access are covered with passcode protection and support for Google Smart Lock. Personalization is a highlight, with customizable ringtones and backgrounds, plus per-contact themes so every conversation looks and sounds distinct.

Daily use benefits from thoughtful touches. A Quick Reply pop-up lets you answer messages while using other apps, and a unified inbox keeps communications from both numbers in one place. For anyone who wants to separate personal and professional communications on a single device, it functions as a practical alternative to carrying two phones.

There are limitations to weigh. New numbers are only available to users in the US and Canada, which rules out sign-ups from other regions. The app can also run into login hiccups, which may interrupt access until resolved.

If you live in a supported country, 2ndLine offers a straightforward path to a second number with meaningful features and minimal cost. The free tier covers a lot, and the overall package makes the premium upgrade worth considering if you need more flexibility.
