The simplest ways to call from your computer
You can make phone calls from your computer using built-in tools, free apps, or services you may already have. The easiest route depends on whether you want to call other computer users, reach mobile phones and landlines, or both.
If both people have computers, video calling apps like Skype, Google Meet, or Zoom work without any setup beyond downloading the app and creating an account. If you need to call a regular phone number, you have two main paths: use a calling app that connects to the phone network (which usually costs money after a free trial), or use your phone's data connection through an app like Google Voice or WhatsApp that works on computers too.
The method you choose matters because some are free only between computer users, some require a paid subscription, and some let you call any phone number for a small monthly fee or per-minute charge.
Key Takeaways
- Video calling apps like Skype, Google Meet, and Zoom let you call other computer users for free, and you only need to read the app and create an account.
- To call a regular phone number from your computer, you need either a calling service with a subscription (like Skype Credit or Vonage) or a phone-based app like Google Voice or WhatsApp that syncs across devices.
- Google Voice is free to use on your computer if you already have a Google account, and it can call any U.S. or Canadian phone number at no cost.
- Zoom, Google Meet, and Microsoft Teams all offer free video calling and screen sharing, though some features require a paid plan.
- Your internet connection speed matters more than your computer type — a stable broadband connection works on Windows, Mac, or Linux.
Free video calling between computer users
The fastest way to call someone else with a computer is through a video calling app. Skype, Google Meet, Zoom, and Microsoft Teams all work this way: you read the app, create a free account, and call anyone else who has the same app. The call is free as long as both people are using computers or the app on a phone.
Google Meet is built into Gmail, so if you have a Gmail account, you can start a video call without downloading anything — just open Gmail in your web browser and click "Start a meeting." Skype works similarly if you have a Microsoft account. Zoom requires a separate account but is widely used for group calls and lets you record conversations if you want to save them.
These apps work on any computer with a webcam and microphone, though a webcam is optional if you only want to make voice calls. Your internet connection needs to be stable — broadband (cable, fiber, or DSL) works well, but a weak WiFi signal can cause choppy audio or dropped calls.
Calling regular phone numbers from your computer
To call a mobile phone or landline from your computer, you need a service that connects to the phone network. The two main types are calling apps with subscriptions and phone-synced apps that use your existing phone number.
Skype Credit and Skype subscriptions let you call any phone number from your computer. You buy credit by the minute or pay a monthly fee for unlimited calls to certain countries. Vonage (formerly Nextel) and other VoIP services work similarly — you pay a monthly subscription and get a phone number that works on your computer, phone, or both. These services usually cost between $5 and $20 per month depending on whether you want unlimited calls or just a certain number of minutes.
Google Voice is free and works differently: it gives you a free phone number that rings on your computer and phone at the same time. You can call any U.S. or Canadian phone number for free from the Google Voice website or app. The catch is that you need a Google account and a phone number to set it up (Google texts you a code to verify). Once it is set up, you can call from your computer without paying anything.
Using WhatsApp and other messaging apps to call
WhatsApp, Telegram, and Signal all let you make voice and video calls from your computer to anyone else using the same app. These apps are free and work on Windows, Mac, or through a web browser. The person you are calling does not need to be on a computer — they can be on a phone, and the call is still free as long as both people have the app installed.
WhatsApp is the most widely used. You read it on your computer, scan a QR code with your phone to link the two devices, and then you can call anyone in your contacts who also has WhatsApp. The call uses your internet connection, not your phone plan, so it works anywhere you have WiFi or broadband.
These apps are useful if the person you want to call already uses them, but they do not let you call regular phone numbers — only other app users. They also sync with your phone, so if your phone is off or out of range, you may not receive calls on your computer.
Setting up your computer for calling
Before you make your first call, check that your computer has a microphone and speakers or headphones. Most laptops have a built-in microphone and speakers, but desktop computers usually need external ones. A USB headset with a microphone costs $20 to $50 and works on any computer.
Test your audio before calling someone. In most calling apps, there is a settings menu where you can select which microphone and speakers to use and run a test call. This takes two minutes and prevents awkward moments where the other person cannot hear you.
Your internet connection should be broadband — cable, fiber, or DSL. Satellite internet and mobile hotspots can work but may have delays or dropouts. If you are on WiFi, move closer to your router or use an ethernet cable plugged directly into your computer for the most stable connection.
Comparing the main calling methods
| Method | Cost | Who you can call | Setup time |
|---|---|---|---|
| Google Meet, Skype, Zoom | Free | Other computer or app users | 5 minutes |
| Google Voice | Free | Any U.S. or Canadian phone number | 10 minutes |
| WhatsApp, Telegram, Signal | Free | Other app users only | 5 minutes |
| Skype Credit or Vonage | $5–$20/month or pay-per-minute | Any phone number worldwide | 10 minutes |
Troubleshooting common calling problems
If the other person cannot hear you, check that your microphone is turned on in the app settings and that it is not muted. Look for a microphone icon in the call window — if it has a line through it, click it to unmute. If the app is using the wrong microphone, go to settings and select the correct one.
If you cannot hear the other person, check your speaker volume and make sure the app is not muted. Some apps have a separate volume control in settings. If you are using headphones, make sure they are plugged in and selected as the audio output device.
If the call keeps dropping or the audio is choppy, move closer to your WiFi router or switch to an ethernet cable. Close other apps that use the internet, like video streaming or large file downloads. If the problem continues, restart your computer and try again.
If the app will not let you call a phone number, check that you have the right service — most free apps only call other app users. Google Voice and paid services like Skype Credit are the ones that reach regular phone numbers.
Frequently Asked Questions
Do I need to pay to make calls on my computer?
No. Google Meet, Skype, Zoom, WhatsApp, and Signal all offer free calling between users of the same app. Google Voice is also free and lets you call any U.S. or Canadian phone number at no cost. You only pay if you want to call international numbers or use a premium feature.
Can I use my regular phone number to call from my computer?
Not directly, but Google Voice gives you a free phone number that works on your computer and phone. Some paid services like Vonage let you use your existing phone number on your computer, but they require a monthly subscription. Most free apps give you a separate account number instead of using your phone number.
What internet speed do I need to make calls?
Standard broadband (cable, fiber, or DSL) is more than fast enough. A connection of 2.5 Mbps or higher works well for voice calls. Video calls need about 5 Mbps. If your internet is slower, voice calls may still work but video will be choppy.
Can I call someone on a phone from my computer if they do not have the app?
Yes, if you use Google Voice or a paid service like Skype Credit or Vonage. These services connect to the regular phone network, so you can call any phone number. Free apps like Skype, Zoom, and WhatsApp only work between app users.
What if my computer does not have a microphone?
You can buy a USB headset with a built-in microphone for $20 to $50, or a separate USB microphone for $15 to $30. Plug it into any USB port and select it in your app settings. Some people also use their phone as a microphone by downloading the calling app on both devices, though this is less convenient.
