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.
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.
You are responsible for complying with SMS regulations in your country, such as TCPA in the U.S., GDPR in Europe, and equivalent laws elsewhere. These typically require obtaining consent before messaging, providing an opt-out option, and avoiding restricted hours. HighSMS helps with built-in STOP/opt-out compliance, automatic opt-out rate monitoring, and spam detection — but it's your responsibility to ensure your messaging practices follow local laws.
Replace Twilio in 3 minutes. No A2P registration, no per-message fees.
