2nd Line+ Second Phone Number

Review by eFreeware

If you have ever handed out your real phone number to a marketplace buyer, a dating app or a sign-up form and regretted it, 2nd Line+ is built for exactly that moment. The app gives you an additional number you can call and text from, without buying a SIM card or carrying a second handset. It is the sort of tool that appeals to people who want one line for the world at large and another for the people who actually matter.

The developer, Text and Call Inc., has gathered more than five million installs and a 4.4 average from over 215,000 ratings, which suggests the basic idea lands with a lot of users. The app is free to download and carries in-app purchases. I would treat it as a utility rather than a social app: you open it when you need a number, not because you want to spend time in it.

What interests me most is the combination of two jobs in one place. A virtual number handles calls, texts and verification codes, while an eSIM section covers mobile data when you travel. Plenty of people juggle separate services for those two needs, so having them under one roof is a sensible pitch.

How the virtual number actually works

The core of the app is straightforward. You pick a number from the countries on offer, and from that point it behaves like a normal mobile line for calling and texting. The developer says activation takes seconds, and no physical SIM is involved. You can hold several numbers inside the same app, which is useful if you want one for work inquiries and another for personal use.

Calls can run over WiFi and VoIP, so the quality of your connection matters more than your carrier. The developer describes the voice calls as high quality and the SMS delivery as reliable, which are the two things any virtual number service lives or dies by. I would expect the experience to be smoothest on a stable home or office network.

Texting works in both directions: you send messages from your virtual number and receive them there too. That two-way flow is what makes the number usable for real conversations rather than one-off codes, and it is the part I would pay closest attention to when deciding whether a service like this fits my habits.

Verification codes and keeping your real number out of it

A large part of the appeal here is registration. The app is designed to receive one-time passwords and activation codes, so you can sign up for messaging platforms, dating apps and other online accounts without typing in your personal number. The developer pitches this as a way to keep your real line away from spam and unwanted calls, and the logic is sound: a number you can discard attracts far less long-term nuisance.

The burner angle follows from the same idea. You can create a temporary number for a short-lived purpose, use it for as long as it is needed, then delete it. That suits classified listings, trial sign-ups, deliveries or any situation where a company wants a contact number and you would rather not hand over the one your family uses.

Coverage is broad. The most popular choices are the United States, the United Kingdom and Canada, with numbers also listed across Europe, Asia and Latin America, including Germany, France, Spain, Japan, South Korea, India, Brazil and Mexico. If you regularly deal with services that only accept certain country codes, that range is the feature that will decide whether this app is useful to you.

Calling and texting abroad

International calling is the second pillar. The rates are affordable, and that distinction matters: this is a calling route with costs attached. You place calls through the app to numbers in other countries.

Texting internationally is presented as unlimited with your second number, which is a generous framing if it holds for your usage pattern. For anyone with family or work contacts spread across several countries, a single app that handles both the message thread and the occasional voice call is easier to manage than juggling separate dialers and messaging tools.

The practical caveat is that calls and messages rely on your connection. Calls go over WiFi or VoIP, so a weak signal affects them the same way it affects any internet call. On a good connection I would expect the experience to feel close to ordinary telephony; on a poor one, it will not.

The eSIM data side for travel

Less expected is the eSIM section. The app lets you compare data plans for different countries, buy one, and connect to a local network when you arrive, with activation described as taking minutes. The stated aim is avoiding roaming charges, which is the standard reason travelers look at eSIMs in the first place.

Pairing this with a virtual number makes a certain amount of sense. On a trip you might want local data for maps and messages, plus a number that is not your everyday line for bookings and inquiries. Whether the eSIM plans themselves are competitive is something you would judge against other travel data options.

I would note that the eSIM feature is a distinct product from the virtual number, not a replacement for it. Data plans give you connectivity; the number gives you an identity to call and text from. They complement each other, and the app is clearly betting that travelers want both in one place.

What you need before installing

The app is free to download, but it is not a free service. In-app purchases are part of the model, and the subscription terms state that payment is charged to your Google Play account once a purchase is confirmed, with automatic renewal unless you cancel at least 24 hours before the renewal date. Managing or canceling happens through your Google Play settings.

That structure is worth understanding before you commit. There are flexible plans for short-term and long-term use, so you can match the commitment to the job at hand, whether that is a two-week burner number or an ongoing second line. What each plan includes is best checked at the point of purchase.

Calls and messages travel over VoIP and WiFi, so the app is only as dependable as your network. The app's own country list is the best guide to what is likely to work.

Who this fits

The clearest fit is someone who wants a boundary between their personal number and the outside world. If you sell things online, sign up for services often, or simply dislike the idea of your real number sitting in a dozen databases, a disposable line solves a genuine problem. The ability to delete a number when it has served its purpose is the part that makes the privacy argument concrete rather than theoretical.

Small operators and freelancers are another natural audience. A second number for client calls and messages keeps work and home separate without a second phone, and multiple numbers in one app means you can organize by purpose. The international calling and texting then covers clients or suppliers in other countries.

Travelers get the most unusual value from the eSIM plans, particularly if they want local data and a separate number for the same trip. The app has been updated recently with faster SMS and better privacy protection, along with new numbers for the US and Canada, so it is being actively developed rather than left to sit.

A second line for people who need one

2nd Line+ does one job well in principle: it gives you a phone number that is not your own, and it lets you call, text and receive verification codes through it without a SIM card. The addition of eSIM data plans makes it more useful for travel than a pure number app, and the country coverage is wide enough to handle most registration scenarios.

The trade-offs are the ones the model implies. You pay through in-app purchases, and the subscription renews automatically unless you cancel in time. None of that is unusual for this category, but it does mean the app is a service you subscribe to rather than a one-off download.

If you want a clean separation between your real number and the rest of the world, this is a reasonable place to start. If you only need occasional verification codes, the same app will do the job, though the subscription is the cost of that convenience. For frequent travelers who also want data, the combination of virtual number and eSIM is the strongest argument for installing it.
