In an era of heightened online security, virtual phone numbers play a crucial role in enabling users to verify accounts, secure two-factor authentication (2FA), and manage multi-region registrations without exposing their personal numbers. But not all virtual numbers are created equal.
Many modern platforms (banks, social media, crypto exchanges, messaging Apps) require users to verify their identity or account via SMS or voice call. For individuals or businesses operating across borders or seeking privacy, physical SIMs are limited or impractical. Virtual numbers provide:
Regional presence. You can appear local in many countries without physical SIMs.
Privacy and anonymity. Your personal phone number stays hidden.
Scalability. Easily create or dispose of numbers as your needs change.
Cost savings. No need for multiple physical SIM plans or roaming.
However, if a virtual number service is of poor quality, verification messages may fail (delayed, blocked, or rejected by platforms). So selection criteria matter.
Some well-known providers include:
Twilio / Nexmo / Plivo. Robust, well-trusted, strong APIs, but relatively higher cost.
Telnyx, MessageBird, SignalWire. Good balance of cost and features.
Burner / Hushed / TextNow. Consumer-oriented, limited in volume or region.
Specialized SMS verification services (some that lease “throwaway” numbers). Sometimes problematic (blocklisting, low reliability).
Each has trade-offs. For instance, cheap “disposable” verification number services often get flagged by large platforms (Google, Meta, etc.). They may also share numbers across many users, which increases the risk of rejection.
That’s why many advanced users prefer virtual number services that combine telecom-grade infrastructure, dedicated numbers, and integration flexibility — and this is where eSIM Plus becomes interesting.
Let’s look at how eSIM Plus aligns strongly with the above criteria:
Wide service offering & dual functionality. eSIM Plus offers both mobile data connectivity and virtual phone numbers/voice & SMS lines. This means users get a multi-purpose communications solution under one roof.
Two-way calls & messages. They support both outgoing and incoming calls and SMS, enabling full verification workflows.
Transparent pricing & no hidden fees. Their site emphasizes “no hidden costs, no roaming fees, transparent conditions.” For verification use, that is critical because you don’t want surprise surcharges per message or call.
Global reach. eSIM Plus supports many countries for both data and numbers, which makes it flexible if you need a number in a specific locale.
App / UX & ease of setup. They provide a mobile App for managing eSIM profiles and numbers, with QR code activations and a user-friendly UI. It lowers friction when onboarding non-technical users.
Reputation & trust. With user reviews (e.g., on Trustpilot) and claims of over 2 million users, they are building social trust.
Combined data + number offering. Because they are also an eSIM data provider, they solve two problems: data connectivity and verification capabilities — useful for travelers, remote teams, or global operations.
All in all, eSIM Plus positions itself as a solid option combining mobility and number services, making it an attractive pick for verification tasks.
To maximize success and avoid issues, keep in mind:
Prefer dedicated / exclusive numbers. Shared or disposable numbers are more likely to be blocked by large platforms.
Warm up numbers gradually. Don’t immediately use a new number for high-volume verifications.
Avoid “frequent reassignments”. Numbers changing users frequently have a bad reputation.
Use multiple providers. Have fallback options in case one service gets blocked by a specific platform.
Respect platform rules/terms of service. Virtual numbers may be disallowed by certain services.
Monitor deliverability & failures. Use analytics/logs to detect dropped or failed SMS/calls.
Choose numbers from diverse carriers. Carriers might blacklist specific ranges.
Secure API integration. Use HTTPS, webhooks, and proper token management.
