myCRMSIM RCS Installation and Setup

Step-by-Step Guide to Connect RCS to Your myCRMSIM Account

 This SOP outlines how to connect and integrate an RCS-enabled Android device to your myCRMSIM account for use with HighLevel CRM.

⚠️ Note:
If a device is being used for myCRMSIM RCS, it cannot be used simultaneously for myCRMSIM SMS. Both services cannot run on the same device at the same time.

Requirements

  1. Active myCRMSIM account
  2. Completed integration with HighLevel CRM
  3. Android smartphone with:
 
⚠️ Note: RCS works only on Android devices using Google Messages. iPhones are not supported for RCS.

💡 Once connected, RCS runs via a cloud connection. Your device needs to be kept on and connected to the internet at all times, and messages will continue to be sent and received via RCS (as long as the cloud session remains active).
 

Step 1: Connect myCRMSIM to HighLevel


1. Log in to your myCRMSIM dashboard.

2. Go to Integrations.

    3. If not connected:

    •  Follow the prompts to authorize.


      For Agency Plans:

      • Click Connect Agency.
      • Install under all locations.
      • Enable Automatic installation for future locations.


        For Starter / $97 Plan:

        • Connect sub-accounts individually.
        • Repeat integration for each location.
        • ✅ Once complete, you will see Integration Successful
         

        Step 2: Connect Sub-Accounts

        1. Go to Sub-Account SIMs.
        2. Click Connect Locations.
        3. Toggle ON the sub-accounts you want to enable.
        4. Click Confirm.

        Agency users can enable all locations at once.
        Starter plan users must connect individually.
         
         

        Step 3: Create a New Chrome Profile (Required)

        Before starting the RCS setup, create a new Chrome profile to maintain an isolated session environment and prevent cookie conflicts that may disrupt the connection.

        1. Open Google Chrome.
        2. Click on your Profile Icon (top-right corner).
        3. Click Add to create a new profile.
        4. Set up the new profile (you can name it e.g., RCS Setup).
        5. In this new Chrome profile:
          • Open your myCRMSIM dashboard
          • You will also use this profile to open Google Messages in the next steps

        ⚠️ Always perform all RCS steps inside this new Chrome profile.
         

        Step 4: Install the RCS Cookie Bridge Extension

      • Download the extension ZIP file from the provided link.
      • Unzip (extract) the downloaded file.
      • Open Chrome and navigate to:
        chrome://extensions/
      • Enable Developer Mode (top-right corner).
      • Click Load unpacked and select the extracted folder.
      • Confirm that the extension appears as RCS Cookie Bridge.
      • Click Details on the extension and enable:
        Allow in Incognito (required for cookie access in the next step).
      • After installation, hard refresh the page:
        • Windows: Ctrl + Shift + R
        • Mac: Cmd + Shift + R
         

        Step 5: Sign in to Google Messages (Incognito Mode Required)

        You must use a Chrome Incognito (private) window.
        A regular window may rotate cookies and automatically disconnect your session.
        1. Open a new Incognito window:
          • Windows: Ctrl + Shift + N
          • Mac: Cmd + Shift + N
        2. In the Incognito window, go to:
          https://messages.google.com/web/config
        3. Sign in with the Google account you want to connect.
        4. In the same Incognito window, open your dashboard and return to the RCS setup screen.
          (The extension only works within the same private session.)
        5. Keep the Google Messages tab open.
        6. Click Continue with RCS on your dashboard.
        7. On your Android device:
          • Open Google Messages
          • Tap the emoji shown on screen to confirm pairing

         Wait for the setup to complete.

        ✅ Your RCS device is now successfully connected and running via the cloud.
         

        Step 6: Name and Assign the RCS Device

        1. In RCS Devices, locate your newly added device.
        2. Click Edit and assign a descriptive name (e.g., Sales RCS Android).
        3. Click Save.
        4. Go to Sub-Account SIMs.
        5. Under the RCS Column, select and attach your connected device.
        6. In Messaging Preference, choose:


          👉 RCS Only
          This ensures all messages are routed via RCS.
           

          Step 7: Configure RCS in HighLevel

          1. Log in to your HighLevel sub-account.
          2. Go to:

          • Settings > Phone Numbers > Additional Settings

               3. Under Telephony Provider, select:


            👉 My SMSGatewayApp – SMS, WhatsApp & iMessage

            This enables RCS messaging inside workflows and manual messages.
             

            Step 8: Sending Messages & Automations

            Manual Messages

            • Send RCS messages directly from contact conversations inside HighLevel.


            • Use the standard SMS provider (RCS will route automatically if configured as RCS Only).
            Automations
            • Use normal HighLevel SMS Actions.
            • RCS messages will send automatically if enabled.


              No additional RCS plan inside HighLevel is required.
              myCRMSIM handles the delivery layer.
               

              Step 9: Test the Connection

              1. Go to Contacts in your HighLevel sub-account.
              2. Send a test message to an RCS-enabled Android number.
              3. Confirm:
              • ✅ Message shows as RCS (chat features enabled)
              • ✅ Message is delivered successfully
              • ✅ Reply is received in both mobile and HighLevel


                If both sending and receiving work correctly, setup is complete 🎉

                  🎯 Best Practices

                  • Keep RCS (Chat Features) enabled in Google Messages.
                  • Ensure your Android device maintains stable internet connection.
                  • Avoid bulk spam messaging.
                  • Monitor device status inside myCRMSIM dashboard.
                  • Regularly check connection health.
                   

                  🚀 Setup Complete

                  Your RCS device is now fully integrated with myCRMSIM and HighLevel, ready to send and receive rich messaging through the unified CRM dashboard.
