SideNumber gives you a second virtual phone number for calls, texts, and messaging over Wi-Fi or cellular—so you can keep your personal number private.
Use SideNumber for calls and texting with your SideNumber line, plus rich messaging features like sending photos and voice/video messages. It’s designed to help you keep your personal number private while still communicating like a regular phone line.
SideNumber calls are placed from the app using your data connection (Wi‑Fi or cellular). To the person you’re calling, it looks like a normal call, but your caller ID is your SideNumber—not your personal number.
No. You can place outgoing calls from SideNumber without a SIM as long as your device has an internet connection (for example, Wi‑Fi). If you’re not on Wi‑Fi, you’ll need cellular data.
When you get a SideNumber, you can typically select from available numbers (often by area code/region). Availability depends on inventory at the time you’re choosing.
No. Your privacy is most important to us, and we don't collect your email address.
No. SideNumber is built so you can use a separate number without sharing your personal phone number with the people you contact.
Calling and SMS/MMS to US and Canada numbers are supported. You need a compatible iOS or Android device and an internet connection (Wi-Fi or cellular).
Use the download links on our home page to download the app from the App Store and Google Play.
Subscription management is handled through your app store account (Apple or Google). For questions about a charge, contact us with the date and amount and we will help investigate.
We built SideNumber to help you separate your side number from your personal line. Read our Privacy Policy for details on what we collect and how we use it.
