How These Apps Work Without SIM

The applications listed above work without a SIM card thanks to VoIP (Voice over IP) technology. Instead of a cellular network, they use Wi-Fi or mobile data to connect to servers through which calls pass. VoIP allows real-time communication by transmitting voice as digital data. So, you do not need a SIM number — just the Internet and an account in the application.

Are These Apps Free to Use?

WhatsApp and Telegram apps are free, meaning you can make calls over the Internet using these messengers. However, you cannot call a regular number through them. You can only make calls if the user has a messenger account.

Google Voice is shareware, it provides free calls to the United States, low tariffs for other countries; it requires activation and is not available in all regions.

eSIM Plus is a paid service that provides virtual rooms as well as affordable eSIM plans.

TextNow provides a toll-free number and also provides free calls in the USA and Canada, but with advertising; calls to international numbers are paid.

What Devices Let You Call Without a SIM Card?

In addition, you can make calls without a SIM card not only from your phone but also using other devices:

• Tablets: using WhatsApp, Telegram, Zoom, etc.
• Laptops: VoIP services (Google Voice).
• Smartwatches: Using Wi-Fi or eSIM (for example, Apple Watch).
• Smart Speakers or Screens: with support for voice calls (for example, Alexa or Google Nest).

The main thing is the availability of Wi-Fi and support for the desired application.

Pros and Cons of Calling Without a SIM Card

The main pros and cons of using calls without a SIM card are listed below:

Advantages:

• For free via Wi-Fi and apps.
• Confidential — you do not need a personal number.

• Dependence on the Internet — there will be no connection without Wi-Fi.

Calls without a SIM card can be safe if you use trusted applications. WhatsApp, Telegram, and Signal, for example, use end-to-end encryption to protect data from outsiders.

If you prefer services that provide virtual numbers, then choose only high-quality services, such as eSIM Plus.

If you follow digital hygiene and security, then all your data will be securely protected.
