Security approaches have become more critical in the current generation, which has used electronic devices for most of its lifetime. The authentication procedure using one-time passwords (OTPs) has become a popular method for identifying account holders, payment validation, and transaction confidentiality. One problem that can affect almost every freelancer, small enterprise, and traveler to other countries is the need to receive SMS and OTPs on time and safely to subscribers’ traditional numbers.

Regular phone numbers may also be problematic since they will cost more to receive SMS or OTPs if you encounter roaming charges, and people might be able to discover your numbers, thus violating your privacy. This is where virtual phone numbers step in, allowing a user to bypass the barriers.

The Limitations of Traditional Phone Numbers

Some problems with traditional telephone numbers preclude their use to receive the OTPs. Using a VoIP phone is particularly beneficial for a freelancer or small business, where numerous tasks must be performed while private information remains private. Barriers for international travelers are more explicit:

  • Roaming Charges: Expensive charges involved when one sends /receives SMS while traveling abroad.
  • Privacy Concerns: Privacy of personal phone numbers is important since there is a threat of exposing them to numerous services.
  • Accessibility: The difficulty of managing OTPs when one has multiple SIM cards or when traveling across countries.

What Are Virtual Phone Numbers?

Virtual phone numbers can be used without a SIM or device. They use 3g for calls and texts and, therefore, can be accessed remotely. Virtual phone numbers also provide additional protection features and the ability to change the number for every OTP transaction. Here’s how they work:

  • Internet-Based: No physical SIM card is required for purchase; instead, it works online.
  • Multiple Devices: One can access it through many smart devices such as phones, tablets, and desktops.


  • Global Reach: The potential for play and sharing even if the user is in another part of the world.

Benefits of Using Virtual Phone Numbers

The advantages of using virtual phone numbers for receiving OTPs are numerous, especially for freelancers, small business owners, and international travelers:

  • Reliable OTP Delivery: Provides secure delivery of OTPs in the shortest time expected to be received by users regardless of where they are.
  • Enhanced Privacy: Hides personal numbers from view, ensuring one is not flooded with random calls and spam.
