Virtual numbers provide a more flexible, cost-effective, and reliable solution for receiving SMS in remote locations compared to eSIM data plans, which depend heavily on cellular coverage and device compatibility.
Virtual Numbers Explained
Virtual numbers are phone numbers that exist in the cloud, not tied to a physical SIM card or device. They allow users to receive SMS messages via online dashboards or APIs, making them ideal for automation and scale.
When you purchase a virtual number, it acts as a proxy phone line. Incoming SMS traffic is routed through SMS verification providers like SMSVerifier, which aggregate messages from multiple upstream carriers worldwide. This setup enables you to receive One-Time Passwords (OTPs) and verification codes instantly without needing a physical phone or SIM.
Virtual numbers support thousands of services including WhatsApp, Telegram, Google, and Instagram, making them highly versatile for SMS verification.
If you're integrating SMS verification into your app or system, virtual numbers provide a straightforward, programmatic way to receive SMS globally via API, even when you are physically located anywhere.
eSIM Data Plans Overview
Embedded SIMs, or eSIMs, are digital SIM cards embedded into devices that allow users to download cellular profiles without swapping physical SIM cards. eSIM technology enables devices like smartphones, tablets, and IoT hardware to connect to mobile networks flexibly.
With an active eSIM data plan, devices can transmit and receive data and, importantly for our topic, SMS messages through the cellular network. This approach mimics traditional SIM functionality but with greater ease of managing multiple carrier profiles.
eSIMs are increasingly supported on modern smartphones and IoT devices, but coverage quality and SMS reception depend on the local mobile network and the specific carrier plan.
In remote locations, an eSIM's ability to receive SMS hinges on local cellular signal availability. Without sufficient coverage, SMS delivery may fail or be delayed.
Reliability in Remote Locations
Reliability for receiving SMS in remote or low-connectivity areas is a critical factor when choosing between virtual numbers and eSIM data plans.
Virtual numbers leverage cloud infrastructure with redundant upstream providers and global number pools. Since they do not rely on your physical location or cellular signal, you can receive SMS anywhere with internet access to your dashboard or API endpoint.
eSIM data plans, on the other hand, depend on the presence and quality of local cellular networks. In remote areas where coverage is weak or intermittent, SMS reception can be unreliable or impossible. Additionally, hardware compatibility and antenna quality impact the signal strength and SMS delivery success.
Relying solely on eSIM data plans in sparsely covered regions may lead to missed OTPs or delayed SMS, causing verification failures and user frustration.
Cost Comparison
Cost efficiency is another major consideration. Virtual numbers typically offer pay-as-you-go pricing, with SMS messages starting from around $0.20 per SMS, and no upfront hardware or monthly fees.
In contrast, eSIM data plans usually involve monthly subscription fees, data charges, and potentially roaming costs if used outside the primary network. If the device is used exclusively for SMS reception, these costs can add up quickly.

Low-cost, no hardware needed, pay per SMS received.
eSIM data plans
Monthly fees plus data charges, higher overall cost for SMS-only use.
Choosing virtual numbers can reduce your cost-per-verification significantly, especially when handling large volumes of OTP requests.
Use Cases and Limitations
Virtual numbers excel in automated SMS verification workflows, bulk OTP reception, and multi-service integration. They support APIs for developers wanting to scale verification without physical SIM constraints.
However, virtual numbers usually support SMS only; voice calls or two-way communication may be limited depending on the provider and country.
eSIM data plans fit scenarios requiring full mobile device functionality, including calls, SMS, and data on a physical device. They are preferred when an actual device endpoint is mandatory, or offline connectivity is crucial.
Virtual numbers are often blocked by some services for registration or may be flagged as suspicious; verify compatibility with your target services.
Best Practices for Remote SMS Reception
For consistent OTP reception in remote areas, consider these recommendations:
- Use virtual numbers when internet access is available but cellular coverage is poor or devices are unavailable.
- Combine eSIM data plans and virtual numbers to balance connectivity and verification needs — use eSIM for general communication, virtual numbers for OTPs.
- Choose providers with multiple upstream SMS carriers to increase delivery reliability and reduce delays.
- Test coverage and service compatibility before committing to a bulk purchase or long-term plan.
