Grasshopper, RingCentral, Dialpad: Why They All Fail at SMS Verification
When it comes to SMS verification, not all phone numbers work. Services like Grasshopper, RingCentral, and Dialpad use VoIP technology, which often gets flagged or blocked by high-security platforms like banks, cryptocurrency exchanges, and government services. These platforms prefer numbers tied to physical SIM cards because they’re harder to spoof and offer better reliability for delivering verification codes.
The problem? VoIP numbers are routed through the internet, making them easy to identify and reject. Even when accepted, delays or missed messages are common, especially for time-sensitive tasks like two-factor authentication. That’s where JoltSMS steps in. Unlike VoIP services, JoltSMS uses real SIM cards, ensuring a 99.9% delivery rate and compatibility with over 1,000 platforms.
Key Takeaways:
- Grasshopper, RingCentral, and Dialpad: Great for business calls but unreliable for SMS verification.
- JoltSMS: Uses physical SIM cards, making it the go-to solution for secure platforms.
Here’s why it matters: If you rely on VoIP numbers for verification, you risk missed codes, blocked access, and unnecessary frustration. Switching to a SIM-based service like JoltSMS solves these issues.
1. Grasshopper
Grasshopper markets itself as a professional business phone service, great for managing calls and voicemails. But when it comes to SMS verification, the service has some hurdles that can leave users stuck, especially on platforms with high-security requirements.
Technology Type
Grasshopper relies on VoIP (Voice over Internet Protocol), meaning it uses the internet rather than traditional cellular networks to function. This setup creates a stumbling block for SMS verification. Many platforms specifically look for numbers tied to cellular networks, as their security systems are designed to distinguish between VoIP and cellular numbers. As a result, Grasshopper’s VoIP numbers often get flagged or outright rejected for verification purposes.
Verification Code Acceptance
Whether a Grasshopper number is accepted depends heavily on the platform. For simpler tasks like signing up for newsletters, these numbers usually work fine. But when it comes to high-security platforms – think financial services, online payment systems, or cryptocurrency exchanges – VoIP numbers are often blocked. Even if accepted initially, accounts tied to these numbers might face issues during later security checks.
Reliability of Inbound SMS
Even when a platform accepts Grasshopper numbers, the reliability of receiving SMS messages can be hit or miss. VoIP numbers are often given lower priority by carrier networks, leading to delays or even missed messages. For time-sensitive tasks like two-factor authentication, this inconsistency can be a major headache.
Platform Compatibility
Many high-security platforms, including those in government, healthcare, and enterprise sectors, prefer cellular numbers for compliance and security reasons. Services like WhatsApp Business, Google Ads, and Facebook Business Manager explicitly require numbers linked to physical SIM cards for verification. These restrictions highlight Grasshopper’s limitations for users needing secure and reliable SMS verification, paving the way to consider better alternatives in the sections ahead.
2. RingCentral
RingCentral is a popular VoIP service designed for business calls and team messaging. However, because it operates over the internet rather than a physical cellular network, its numbers aren’t always suitable for SMS verification. Much like Grasshopper, RingCentral’s setup makes it less compatible with platforms that require stringent SMS verification tied to physical SIM cards.
Technology Type
RingCentral relies on VoIP technology, meaning its phone numbers are digital rather than tied to a physical SIM card. Many verification systems prioritize numbers linked to cellular networks, so RingCentral’s numbers are often flagged as VoIP and may face compatibility issues.
Verification Code Acceptance
Since RingCentral uses VoIP numbers, some high-security platforms – like financial institutions or government services – may block them. While basic services, such as social media accounts or newsletter subscriptions, might accept these numbers, issues can arise later. For example, numbers that work during registration may fail during two-factor authentication due to their non-cellular nature and potential delays.
Reliability of Inbound SMS
During periods of high traffic, SMS delivery to RingCentral numbers can experience delays. These delays can be particularly problematic for time-sensitive verification codes, where quick access is critical. This lag further reduces the reliability of RingCentral numbers for platforms that emphasize security.
Platform Compatibility
As security standards become stricter, many platforms now favor numbers linked to physical SIM cards. This shift has made it increasingly difficult for RingCentral’s VoIP numbers to meet updated verification requirements, leading to re-verification challenges on some services.
While RingCentral excels as a business communication tool, its VoIP-based design limits its effectiveness for SMS verification purposes.
3. Dialpad
Dialpad presents itself as a comprehensive business communications platform, offering calling, messaging, and video conferencing all in one place. While it performs well for general business communication, it runs into hurdles when dealing with SMS verification. Like most VoIP services, its cloud-based infrastructure limits its ability to meet the requirements of platforms that prioritize traditional cellular connections.
Technology Type
Dialpad operates on a cloud-based VoIP system, which means its numbers aren’t tied to physical SIM cards or cellular networks. This setup allows for features like switching between devices effortlessly and providing detailed call analytics. However, these benefits don’t translate to success in SMS verification. Many platforms that require verification codes prefer numbers linked to cellular networks, something Dialpad can’t offer due to its design.
Verification Code Acceptance
Dialpad numbers are often blocked by platforms with strict security measures. This includes banking apps, cryptocurrency exchanges, and government websites. Such services typically reject VoIP numbers during account registration or login attempts. This can create significant issues for users during critical moments like resetting passwords or completing two-factor authentication.
For businesses relying on Dialpad as their primary contact method, this limitation can disrupt essential operations. Verification codes from services like payment processors or tax platforms may fail to arrive, causing delays and workflow interruptions.
Reliability of Inbound SMS
The routing process for VoIP numbers can lead to delays or even blockages of time-sensitive verification codes. Instead of arriving within seconds, these codes might take several minutes – or not arrive at all. In some cases, the delay can render the code invalid before users have the chance to complete their authentication.
Platform Compatibility
As security protocols continue to evolve, more platforms are rejecting VoIP numbers for verification purposes. Social media networks, financial institutions, and e-commerce sites are increasingly adopting detection systems that flag and block non-cellular numbers.
This trend has made it harder for users to rely on Dialpad numbers for verification. Even accounts that were successfully verified in the past may face re-verification issues during security updates or when switching devices. These challenges highlight the need for businesses to consider alternative solutions that are more reliable for SMS verification needs.
