How a GoHighLevel SMS Gateway Works
Connect an Android device and mobile SIM to your GoHighLevel agency so your team can keep sending and receiving SMS inside the workflow they already know — using SIM-based transport rather than the traditional LC Phone/Twilio application-messaging route.
From device to conversation.
The exact provisioning flow can vary by account and hardware, but the architecture stays straightforward.
Connect Your Android Device
Use a compatible Android phone with an active SIM and data/Wi-Fi connection. The underlying platform supports Android 8.0+, although ASG recommends a newer dedicated device for production reliability.
Connect Your GHL Account
Authorize the integration so messaging can flow between your GHL environment and the gateway.
Configure Numbers & Locations
Map your connected mobile-number resources to the GHL locations you intend to support, based on the supported routing configuration.
Test, Warm Up & Deploy
Verify inbound/outbound delivery, reply routing, opt-out behavior, and your agency workflow before production use.
Get more flexibility from compatible Android devices.
HighSMS supports dual-SIM capable Android devices. That can give one physical device access to two mobile-number resources. Exact routing and assignment should be validated for your deployment before promising a specific client-to-SIM topology.
- Compatible dual-SIM Android hardware supported
- Two carrier SIMs can live in one physical device
- Useful for redundancy, number flexibility, and device efficiency
- We validate your planned GHL routing before deployment
Automation and engagement tools built around the transport.
Once the Android + SIM connection is in place, ASG adds tools agencies can use directly or package into client services.
AI Auto-Reply + Knowledge Base
Use your own OpenAI key to support AI-assisted SMS responses and knowledge-driven interactions.
Campaigns, Scheduling + Drips
Run scheduled campaigns and automated sequences without building the entire messaging layer from scratch.
Keyword + Custom Variables
Capture responses and personalization data that can feed more useful automation.
URL Click Tracking
Shorten links and track engagement to give agencies more visibility into SMS performance.
Warm-Up + Opt-Out Tools
Use a structured warm-up toolset and STOP/opt-out handling as part of responsible deployment.
API + Webhooks
Connect other agency systems through REST APIs, webhooks, and phone-verification workflows.
Built to organize multiple client deployments.
The underlying platform supports separate client sub-account logins, multiple GHL locations through the connected integration, dual-SIM capable Android devices, APIs, webhooks, templates, contact management, scheduled campaigns, and automated messaging tools. ASG wraps those capabilities in a managed agency service.
We test the path before you rely on it.
Device & Connectivity
Confirm the Android gateway stays online, has carrier service, and can operate reliably in the background.
Messaging & Routing
Run inbound, outbound, reply, workflow, and STOP handling tests before production deployment.
Responsible Messaging
Use opt-in messaging, respect opt-outs, and operate within carrier fair-use and applicable legal requirements.
