Finding the best free apps to call and text over Wi-Fi can save you a lot of money on your phone bill. Several official apps let you call and message people using the internet, and some even give you a free second phone number in the United States, which is useful for work, online sales or simply protecting your privacy.
In this guide you will learn which free calling and texting apps are the most useful, how second-number apps differ from internet messaging apps, how much data calls use, which limits apply to free services and how to protect your privacy. You will also find a comparison table and a simple method to choose the right app for your needs.
Direct answer: use TextNow or Google Voice if you need a free second US phone number for calls and texts, and use WhatsApp for free voice and video calls with people who also have the app. All three work over Wi-Fi or mobile data, so calls usually cost nothing beyond your existing home internet connection or mobile data plan.
Calling over Wi-Fi has become normal. Messaging apps replaced many traditional calls, and second-number apps give people an extra line without paying for another plan. The right choice depends on who you want to call: people who already use the same app, or regular phone numbers in the United States and Canada through a free online number.
A common mistake is using an internet number for important verification codes and then losing access to it. Free numbers can be reclaimed when inactive, and some banks do not accept internet-based numbers. Keep your main carrier number for critical accounts and use free apps for everyday calls, marketplace contacts and online sign-ups.
Next, you will see a comparison of the main free calling apps, how to choose between a second number and a messaging app, how to improve call quality, how much data calls use, privacy and safety tips and a short checklist to set up free calls and texts on your phone without changing your current mobile plan or carrier.
Free calling apps compared
| App | Type | Free calls to | Best for |
|---|---|---|---|
| TextNow | Second number | US and Canada numbers | A free extra line with ads |
| Google Voice | Second number | US and Canada numbers (personal accounts) | One number on several devices |
| Messaging app | Other WhatsApp users worldwide | International calls and video |
Second number or messaging app?
A second-number app gives you a real phone number that anyone can call or text, even if they do not have the app. A messaging app only works between people who use the same app, but it usually offers better video and group calls. Many people use both: a second number for business and WhatsApp for family and friends.
How to improve call quality
- Use a stable Wi-Fi connection when possible.
- Keep apps updated.
- Close apps that use bandwidth during calls.
- Turn off video when the connection is weak.
- Restart your router if calls drop often.
Data usage
Voice calls use relatively little data, while video calls use much more. If you have a limited mobile plan, make video calls on Wi-Fi and enable data-saving options in the app settings. Checking your data usage in the phone settings helps you avoid surprises at the end of the month.
Privacy and safety tips
- Never share verification codes with anyone.
- Use strong passwords and two-step verification.
- Be careful with unknown callers asking for money or codes.
- Use a second number for marketplaces and online ads.
Quick setup checklist
- Decide whether you need a second number, a messaging app or both.
- Install the apps from the official stores.
- Verify your accounts and enable security options.
- Test calls on Wi-Fi and mobile data.
- Keep your main number for banking and important services.
When to keep using your carrier
Free calling apps are excellent for everyday conversations, but your carrier number is still important. Use it for emergency calls, banking verification codes and services that do not accept internet numbers. Keeping both options gives you the savings of free apps and the reliability of a traditional line.
If your current plan includes more minutes than you use, consider moving to a cheaper plan with more data and fewer minutes, since most of your calls can now happen over the internet.
Using free calls while travelling
When you travel abroad, free calling apps can help you avoid roaming charges. Connect to hotel or cafe Wi-Fi and use WhatsApp, TextNow or Google Voice to stay in touch with people at home. Turn off mobile data roaming in your phone settings to make sure you do not receive unexpected charges.
Before the trip, test the apps at home and make sure all your contacts know the number or app you will use while you are away.
Start with one app today, test a few calls on Wi-Fi and add a second app only if you need a separate number or better video quality for your contacts.
Small changes like these can lower your monthly phone costs noticeably.
