In their own words
D7 Networks
D7 Networks provides messaging and verification services through web access and APIs, including SMS, WhatsApp, Viber, number lookup, and two-factor verification. Its SMS API supports single or bulk messages in any language and can reach mobile networks worldwide. A no-code WhatsApp chatbot builder supports customer service automation, appointment management, feedback collection, and lead qualification. Chatbot tools include ChatGPT integration, interactive buttons and flows, a shared inbox, templates, and analytics. The Number Lookup API checks whether a number is valid and reachable, and returns country code and carrier information; new users receive 10 test credits with unlimited validity. REST API features include batch processing, scheduling, status webhooks, higher throughput, and request validation. SDKs are listed for Python, Ruby, Node.js, PHP, and Go. D7 states it is ISO/IEC 27001:2022 certified and encrypts critical data at rest and in transit. API authentication uses OAuth 2.0 bearer tokens, with TLS and SSL support. The company was founded in 2014 and is headquartered in Dubai.
simhook
SimHook turns an Android phone with a SIM into an SMS gateway and API for sending and receiving texts. API messages travel through the paired phone, while incoming texts can be forwarded as webhooks. Signed webhooks report sent, delivered, and failed status changes; they are retried for two days and paused if an endpoint keeps failing. The service also supports scheduled sends, multiple recipients, and dual-SIM phones, with a SIM selectable for each message. Its TypeScript SDK supports Node and edge runtimes, and an MCP server provides eight tools for AI agents. API keys can be limited by scope, including a send-only option. The Android app requires Android 8.0 or newer and is distributed as a signed APK. The full stack can be self-hosted from one Compose file under AGPL-3.0, which the maker says is free without limits. Hosted accounts are currently on Free; listed paid plans open soon. The maker says the service is not for bulk marketing or unsolicited texts.
