1. Definitions

For purposes of this document, the following terms have the meanings stated unless the context requires otherwise. Platform means the Global SMS Verification Platform, its APIs, dashboards, and hosted services. Client means any organization or legal entity that subscribes to or uses the Platform. OTP means a one time password used to verify a user’s identity or access. Fake number otp refers to attempts to use non verifiable or non assigned numbers to bypass verification; the Platform does not support or assist such activities. megapersonal is referenced as a virtual number provider; megapersonal pools may be used in accordance with regional rules and legitimate business needs. Vietnam denotes the regional market with its own regulatory and privacy requirements. Free SMS for verification means a defined quota of verification messages offered at no charge for onboarding, testing, and QA. API refers to the Platform's application programming interface. SLA means the service level agreement detailing uptime, performance, and support commitments. PII means personally identifiable information as defined by applicable law and regulation.

2. Scope

The Platform provides virtual numbers, SMS routing, and OTP delivery capabilities to support verification workflows, onboarding, and customer engagement. The primary value proposition centers on reliable free verification messages for testing, followed by scalable usage and commercial terms for production environments. The architecture encompasses API access for number provisioning, OTP dispatch, sender ID customization, webhook event delivery, and robust reporting. Coverage spans multiple regions with particular emphasis on Vietnam and nearby markets to support regional onboarding, data privacy alignment, and regulatory compliance. The Platform is designed to operate with high availability, predictable latency, and transparent billing to support enterprise deployments in regulated industries.

3. Allowed Use and Free SMS for Verification

Allowed use includes legitimate verification flows such as user onboarding, password resets, account recovery, and two factor authentication via OTP messages to real end users who have provided consent and whose data is processed in accordance with the Client's privacy policy. The Free SMS for verification tier provides a baseline quota to support onboarding and QA environments. Usage beyond the free quota is billed per message, destination, and routing path, according to the current rate card. The Free SMS for verification is subject to compliance checks and anti abuse controls. The Platform reserves the right to suspend or terminate free credentials if fraud, abuse, or policy violations are detected. Free verification should not be used to circumvent security, degrade protection, or facilitate illicit activity.

4. Prohibited Activities

Prohibited activities include but are not limited to the use of the Platform to generate fraudulent OTP requests, to deploy fake number otp schemes, to misrepresent recipients, or to access accounts without proper authorization. The Platform prohibits the use of virtual numbers or sender identities that are not owned or controlled by the Client or for which the Client lacks explicit consent for data processing. Attempts to spoof sender information, bypass rate limits, exploit vulnerabilities, or engage in mass unsolicited OTP campaigns are strictly forbidden. The Platform employs fraud detection, carrier level checks, and anomaly detection to protect the integrity of the network and the Client’s reputation. Any activity that undermines security, privacy, or compliance will trigger immediate assessment, potential suspension, and possible legal action as permitted by applicable law.

5. Technical Architecture and How It Works

The Platform operates on a modular, microservices based architecture designed for scalability, reliability, and security. Core components include a Numbers Gateway sourcing virtual numbers from vetted providers, including megapersonal pools where appropriate, a Routing Engine that selects optimal carriers based on destination, a Delivery Layer that composes and dispatches MT SMS while respecting local regulatory rules, and a Telemetry subsystem that records delivery receipts, statuses, timestamps, and analytics. Integrations are performed through RESTful APIs secured with OAuth 2.0, with support for API keys, IP allowlists, and TLS 1.2+ for all communications. Webhook callbacks enable real time event streaming for delivery results, failures, and user status updates. The Platform supports bulk provisioning, template based OTP messaging, per destination pricing, and sender ID customization for enterprise branding. Data separation is maintained between production and testing environments, and all sensitive data handling follows best practices and regulatory requirements.

6. Global Coverage and Vietnam

The Platform offers global reach through a combination of direct carrier connectivity and reputable provider networks. OTP routing is optimized for latency, reliability, and compliance, with dynamic failover and monitoring across regions. In markets such as Vietnam, regulatory considerations include local message formatting, sender ID policies, and potential data localization requirements. The Platform provides transparent notices regarding data residency options and supports localization of privacy materials in local languages where required. Enterprises deploying OTP verification in Vietnam can leverage regional routing strategies, while maintaining oversight through comprehensive analytics, dashboards, and audit trails. The global architecture is designed to minimize latency to end users while preserving regulatory compliance and data protection standards across all jurisdictions.

7. Data Privacy, Security, and Compliance

Security and privacy are foundational to the Platform. All data is encrypted in transit using TLS and at rest with industry standard encryption. Access control uses role based access and multi factor authentication for privileged accounts. The Platform adheres to applicable data protection laws, including GDPR for EU regions, CCPA for certain US based processing, and local regulations in Vietnam. Data processing agreements, DPIAs, and data localization options are available upon request. The Platform implements data minimization, retention policies, and secure deletion procedures for test and production data. Logging and telemetry are designed to support security monitoring and compliance reporting without exposing sensitive information. The Platform provides clients with notice of data processing activities and offers tools to control data sharing with partner networks.

8. Fraud Prevention, Abuse Mitigation, and Compliance Monitoring

Fraud prevention is embedded in every layer of the Platform. Behavioral analytics detect anomalies in OTP requests, destination patterns, and recipient responses. The system enforces rate limiting, IP reputation checks, device fingerprinting, and cross correlation against known fraud signals. The Platform actively blocks or suspends suspicious activity, including attempts to use fake number otp or other techniques to evade verification. Clients are responsible for maintaining legitimate business records, performing KYC where appropriate, and complying with their own terms of service. The Platform provides risk metrics and anomaly alerts to help clients optimize their verification funnels, reduce fraudulent activity, and maintain a trustworthy user experience.

9. API Access, Webhooks, and Integrations

The Platform exposes a robust API for provisioning numbers, sending OTP messages, querying delivery status, and retrieving analytics. API authentication uses OAuth 2.0 with access tokens and refresh tokens. API endpoints support template management for OTP content, sender ID configuration, and real time event notification via webhooks. Webhook event retries, backpressure handling, and secure endpoint validation are standard features. The API documentation covers versioned endpoints, test modes, sandbox environments, rate limits, and best practices for enterprise deployments. The Platform also supports integration with identity and access management systems, CRM platforms, and data analytics tools, ensuring a seamless workflow for Vietnam based teams and international operations alike.

10. Service Levels, Reliability, and Maintenance

The Platform is backed by a service level commitment that includes uptime targets, maintenance windows, incident response times, and customer support SLAs. The architecture employs multi region redundancy, live failover, automated health checks, and auto scaling to sustain high availability for OTP delivery. Scheduled maintenance is announced in advance with expected impact, while emergency maintenance is executed with minimal disruption. For the Free SMS for verification tier, the platform ensures consistent baseline performance to support onboarding and QA, while applying fair use policies and anti fraud controls to protect the network and clients alike. Clients can access status dashboards and receive proactive notifications of incidents and resolutions.

11. Billing, Free Tier, and Pricing

Pricing is based on message class, destination country, and routing path. The Free SMS for verification tier provides a clearly defined quota designed to support onboarding and testing workflows. Usage beyond the free quota is billed per message with detail line items including origin, destination, carrier, timestamp, and status. The Platform offers volume discounts, tiered pricing for repetitive OTP campaigns, and enterprise contracts for long term engagements. Invoices are accessible via the client portal and exportable for internal accounting. Payment methods must be valid, and refunds follow the documented policy. The Platform reserves the right to adjust pricing and terms as the service evolves, with advance notice to clients. Abuse or policy violations may trigger suspension of services and termination of free trial access if necessary.

12. Termination, Suspension, and Renewal

Either party may terminate the agreement in accordance with the termination clause. The Platform may suspend access for security violations, breaches of policy, or non payment. Upon termination, data retention policies apply, with a defined period for export and secure deletion thereafter.
