Connecting Multiple RCS Devices to a Single Sub-Account in HighLevel CRM

🚀 Overview

This SOP explains how to connect multiple RCS Android devices to the same HighLevel sub-account.

This is useful when:

Multiple team members need to send messages using their own Android numbers
You want to increase messaging capacity across different devices
You want conversations to come from assigned agents’ numbers

✅ Prerequisites

Before starting, ensure the following:

RCS Devices Installed & Connected

Each Android Number requires its own connected RCS device.
Follow the RCS Installation Guide first.

Users Created in Sub-Account

Each RCS number should be assigned to a user.
Create additional or dummy users if required.

⚙️ Step-by-Step Setup

1. Verify Devices

Navigate to:
Devices → RCS Devices
Confirm:

First RCS device is already attached
Second Android device is connected but not yet assigned

2. Assign RCS Device to User

Go to your Sub-Account
Click Assign New RCS Device
Select the user you want to assign
Choose the second Android device
Click Assign

Repeat for additional team members if needed.

3. Set Messaging Preferences

Go to:
Settings → Preferences
Choose messaging order (example):
RCS → iMessage → SMS

RCS will always be attempted first, then fallback channels if unavailable.

💬 How Messaging Works with Multiple RCS Users

▶️ Automated Messages (Workflows)

Leads assigned to a user receive messages from that user’s RCS number
If reassigned, future messages send from the new assigned user’s device

✉️ Manual Messages (Conversation Tab)

By default:
Messages send from the logged-in user’s RCS device

To Send From the Correct Number

Option 1 — Switch User
Log in as the user assigned to the lead and send manually.

Option 2 — MultiSIM Message Override (Recommended)
Install the myCRMSIM Snapshot and enable the override workflow.
Messages automatically send from the assigned user’s RCS device — even if another user is logged in.

⚖️ Message Volume Tips

RCS behaves like conversational messaging and should be warmed gradually:

Recommended: ~1 message per minute per device initially
Increase slowly after consistent usage
Avoid bulk spam behavior

For large campaigns:
Use RCS + SMS fallback (Android SIM) instead of only RCS.

🎯 Final Notes

Each Android device equals one RCS sender
More devices = higher throughput capacity
Best used for conversational messaging and engagement

Your multi-device RCS setup is now ready for team usage 🚀
