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 virtual phone number for talk, text and picture messaging across the US and Canada. Use it as a burner number for classified ads, a business line for your side hustle, or an anonymous text line for anyone who doesn't need your real number. When you make a call or text with Side Number, it's sent from a new number that's assigned to you. Your real number will not show up to the receiver. Side Number makes it possible to have different lines for your personal and business needs without an extra SIM. The app allows you to choose a custom phone number and make phone calls without displaying your real number. There is no need to buy an additional SIM card and swap it when you want to call from a different number. Now you can make calls from different numbers quickly. WHY A BURNER SECOND PHONE NUMBER Most calling apps give you one line and leave you stuck with it. Side Number lets you add a burner phone number in a few taps and keep separate lines for the different parts of your life. Sell an item, meet someone new, sign up for a service — each one can have its own number. And unlike a fake phone number app, every Side Number line is a real, working number. Real calls, real SMS, real MMS. No fake call screens, no gimmicks, no throwaway text that bounces back. USE IT INSTEAD OF YOUR ACTUAL PHONE NUMBER * Classified ads: buying or selling things on local e-commerce platforms. Use a temporary number to post your ads and receive calls, then delete it after the deal is done. * Dating. Giving out an alternative number to your new acquaintance from one of those dating apps can be a good idea. Just in case ;) * Business needs (e.g., as a second work number). Separate work and personal calls. * Managing real estate properties. * Renting a car. * Signing up on websites and social networks that prompt for a phone number. Verification codes arrive right in the app. * Travel — use it as a temporary number with hotels, restaurants, clubs, etc. Family and friends can reach you on a local number without having to pay long-distance or roaming charges. Stay safe and anonymous when you give out your number while using any public service. FEATURES — Choose your number from a list of available numbers, including your preferred area code. — Get extra numbers for calls and texting. Add a number with just a few taps and delete it if you don't need it anymore. — Send SMS and view your full text message history. — Send MMS (available for US and Canadian numbers). — Receive verification codes: sign-up and login codes from most sites and apps land in your Side Number inbox, so you can register for things without handing over your personal number. — Voicemail: Missed calls go to your side line's voicemail, not your real one. Recordings land in the app, sorted by number, ready to play back whenever you are. — Voice Changer: Shift your pitch, deepen your tone, or mask your voice entirely — one tap during a live call. The other side hears a different voice. Yours stays private. — Works over Wi-Fi or your cellular data, so your iPad or tablet becomes a real phone. — Optionally access your contacts for easy calling and texting. Contacts are used only locally for convenience; the app does not upload user contact data to a server. A CALL APP AND TEXT APP IN ONE Other burner phone number apps make you pick between a phone call app and a text app. Side Number is both — a full second line with calling, texting and picture messaging on the same number. Save your real personal number for people you trust. Use Side Number for everything else. Side Number is easy and risk-free. Keep your conversations private. No ads, no contracts, and signing up doesn't require any verification. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
