Call.com – Second Phone Number App

What is Call.com?

Call.com is an Android application that creates a virtual telephone line you can use alongside your regular mobile number. The service works over data or Wi‑Fi, so you never need an extra SIM card or a separate device to make and receive calls, send SMS messages, or start video conversations.

Main features

• Separate line – Keep personal and professional communications distinct with a dedicated number.
• Voice calling – Place clear voice calls to mobile phones and landlines worldwide.
• Text messaging – Send and receive SMS from the virtual number.
• Video calls – One‑to‑one or group video chats with up to ten participants.
• Messaging tools – Exchange images, files, emojis and voice notes within the app.
• Voicemail – Personalized voicemail greetings for each virtual number.
• Call & SMS forwarding – Forward incoming calls or messages to another number if you prefer.

How it works

After installing the app, you create an account and choose a virtual number from the list of available options. The number is linked to your Google Play account, not to any physical SIM. All communication is routed through the app’s servers and delivered over the internet. When you receive a call or message, the app notifies you just like any other messaging app, and you can answer or reply directly from your Android device.

Practical uses

Having a second number can be useful in many scenarios:

• Freelancers and small businesses – Present a professional contact number without exposing your personal line.
• Travelers – Stay reachable on a local number while abroad, avoiding roaming charges.
• Remote teams – Share a company‑wide virtual number that can be reassigned as staff change.
• Expats and digital nomads – Keep a home‑country number for banking, government services or family contact.
• Tablet owners – Turn a tablet into a fully functional phone.

Frequently asked questions

Do I need a SIM card?

No. All communication runs over data or Wi‑Fi, so a physical SIM is not required.

Can I receive calls when I’m offline?

Calls are delivered as push notifications. If your device is offline, you will receive them once you reconnect to the internet.

Is the app secure?

Call.com uses standard encryption for data transmission. As with any communication app, you should keep the app updated to benefit from the latest security improvements.

Can I use the same virtual number on multiple devices?

The virtual number is tied to a single account. You can log in on another Android device, but simultaneous use on multiple devices is not supported.
