2nd Line - Second Phone Number

What it does

2nd Line adds a separate phone number for calling and texting, so users can keep some conversations apart from the number they use personally. It is aimed at people who want a distinct line for work, online buying and selling, job searches or other contacts they do not want to route through their main number. The listed calling and texting coverage is for the US and Canada.

Who it may suit

The main use is separation, not replacing every function of a mobile carrier. A small-business owner, for example, could use the extra number for customer calls; someone selling items online could use it for enquiries. The app also lists voicemail greetings, call forwarding, call recording and spam-call blocking. Those options may be useful, but a second number is not a guarantee of anonymity: people may still identify you through what you share or how you use the number.

How it compares

Compared with using a second SIM or an additional carrier line, an app-based number keeps the extra line within the app rather than on a separate SIM. That can be convenient for users whose needs are mostly calls and texts, but it is not the same as having another carrier connection. The reference information describes Wi-Fi calling, so call quality and availability may depend on the internet connection. Users who need broad international coverage or a line that works independently of an app should check whether this arrangement fits before relying on it.

Reach and track record

2nd Line is published by Dingtone Communications Ltd in the Communication category. Its listing shows more than 10 million installs and a 4.27 rating from about 47,500 ratings, suggesting substantial uptake, though ratings do not establish how well it will work for a particular user. The app is worth considering when the priority is a separate US or Canadian number for everyday calls and texts; compare its terms and available calling options with other second-number services before choosing.
