HighSMS turns your Android phone into an SMS gateway. Instead of paying Twilio per message, connect your phone and send unlimited SMS through GoHighLevel, our dashboard, or REST API. Messages come from your real phone number — no virtual numbers, no A2P registration.
No. Since messages are sent from your own phone's SIM card, there's no A2P 10DLC registration required. You skip the weeks-long approval process entirely and start sending immediately.
Connect HighSMS as a custom SMS provider in GoHighLevel using our API. All your GHL automations, workflows, conversations, and campaigns will send SMS through your own phone instead of Twilio. Setup takes about 5 minutes.
Any Android phone running Android 8.0 or higher. We recommend using a dedicated spare phone with an unlimited SMS plan. Dual SIM phones are fully supported — choose which SIM sends each message.
Yes. The number of devices depends on your plan — Solo supports 2, Growth supports 25, and Scale has no limit. Each phone sends independently, so multiple devices multiply your throughput. Perfect for agencies managing multiple numbers or high-volume sending.
Yes. All message content is end-to-end encrypted with AES-256 between your phone and the server. Your encryption key never leaves your device — it's set once via QR code and never transmitted over the network.
SMS warmup gradually increases your daily sending volume over 6 weeks. This builds trust with carriers so your messages don't get flagged as spam. HighSMS handles this automatically — just enable warmup on your device and we'll ramp up the volume for you.
When enabled, HighSMS automatically detects opt-out keywords (STOP, END, CANCEL, QUIT, UNSUBSCRIBE) and blocks further messages to that number. When they text START, they're resubscribed. You can customize the opt-out footer text per device.
HighSMS monitors your opt-out rate in a 24-hour rolling window. If more than 5% of recipients reply STOP, sending is automatically paused to protect your number from carrier spam flags. Once the rate drops below 3%, sending resumes automatically. This only kicks in after you've sent 1,000+ messages.
When a call to your phone goes unanswered, HighSMS automatically sends a customizable text to the caller — like "Hey, I missed your call! How can I help you?" If the caller replies and AI auto-reply is enabled, the AI continues the conversation automatically. Never lose a lead to a missed call again.
GHL agencies are saving thousands per year with HighSMS.
