SMS Installation & Setup

Guide for users step-by-step in integrating their HighLevel account with MyCRMSIM for SMS messaging services.

• An active MyCRMSIM account.

• Access to your HighLevel agency or sub-account.

• You must be logged in to the main HighLevel app (not your white-label domain).

• Visit MyCRMSIM dashboard and log in.

• You'll land on the main page (it may look empty if no messages exist yet).

1. Navigate to the Integrations tab.

2. Click "Connect with Agency" or "Connect with Your Account".

   • If reconnecting, click "Reconnect" instead.

3. You will be redirected to the HighLevel Marketplace App.

4. Important: Ensure you're logged into app.gohighlevel.com, not just your white-label domain.

1. On the HighLevel Marketplace App page, click Next.

2. If you're an agency user:

   • Select Connect Agency.

   • Choose Install under all locations.

   • Enable automatic installation for future locations.

3. If you're on the $97 plan (3 sub-accounts):

   • Connect sub-accounts individually.

   • Repeat this integration process for each sub-account.

• Choose all conversation providers when prompted (recommended).

• These include:

  • Android SMS

  • WhatsApp

• All providers are white-labeled under "My SMS Gateway App" — clients will not see MyCRMSIM branding.

2. Click Connect Locations.

3. Toggle on the sub-account(s) you wish to connect.

4. Confirm with "Yes".

1. Log into the connected sub-account in HighLevel.

2. Go to Settings > Phone Numbers > Additional Settings.

3. Under Custom Provider, change from "LeadConnector" or "Twilio" to:

   • SMS WhatsApp iMessage Gateway – if using Android SMS or a combination of services.

   • iMessage Gateway – if using only iMessage.

4. Click Save.

You have now:

• Integrated your agency/sub-account with MyCRMSIM.
