A 2nd line for private calls, texting and pictures. No ads, ever. Side Number is a phone call and texting app that gives you a real second phone number for talk, text and picture messaging across the US and Canada. Use it as a temporary number for classified ads, a business line for your side hustle, or a separate line for anyone who doesn't need your personal number. When you make a call or text with Side Number, it's sent from the number assigned to you, so your personal number stays private. Side Number makes it possible to have different lines for your personal and business needs without an extra SIM. Choose your own phone number and keep your personal number for the people you know best. There is no need to buy an additional SIM card and swap it when you want to call from a different line. Switch between your numbers in seconds. WHY A SECOND PHONE NUMBER Most calling apps give you one line and leave you stuck with it. Side Number lets you add a second phone number in a few taps and keep separate lines for the different parts of your life. Sell an item, run a side business, rent out a property — each one can have its own number. Every Side Number line is a real, working phone number. Real calls, real SMS, real MMS. KEEP YOUR PERSONAL NUMBER PRIVATE * Classified ads: buying or selling things on local marketplaces. Use a temporary number for your listing. * Meeting new people: share a second number until you're ready to share your personal one. * Business: a second work number that keeps work and personal calls separate. * Managing rental and real estate properties. * Renting a car. * Online accounts: give your second number to websites and services that ask for a phone number, and keep your personal number off their lists. * Travel — use it as a local number with hotels, restaurants and tours. Family and friends can reach you on a local number without paying long-distance or roaming charges. Protect your privacy when you share your number with businesses and public services. FEATURES — Choose your number by city, state or area code, or pick one at random. — Add extra numbers for calls and texting in just a few taps, and delete a number when you no longer need it. — Send SMS and view your full text message history. — Send MMS (available for US and Canadian numbers). — Voicemail: missed calls go to your second line's voicemail.

Contacts are used only on your device; the app does not upload your contacts to a server.
