# SMS Online GH - Quick Fix for HSHK_ERR_MR_MESSAGE

## The Problem

Error `HSHK_ERR_MR_MESSAGE` means SMS Online GH rejected your message. The most common cause is **unapproved Sender ID**.

## Quick Solution

### Option 1: Use Default Sender ID (Recommended)

1. Contact SMS Online GH support and ask: **"What is my default sender ID?"**
2. They will give you a sender ID (usually something like "SMSOnline" or a number)
3. Go to Admin Settings → SMS Configuration
4. Change "Sender ID" to the one they provided
5. Save and test again

### Option 2: Get Your Custom Sender ID Approved

1. Log in to SMS Online GH dashboard
2. Go to Sender ID section
3. Request approval for "RMBXchange" (or your preferred name)
4. Wait 24-48 hours for approval
5. Once approved, test again

### Option 3: Switch to BulkSMS Ghana (Temporary)

If you need SMS working immediately:

1. Go to Admin Settings
2. Change "SMS Provider" to "BulkSMS Ghana"
3. Sign up at https://bulksmsghana.com
4. Get your API key
5. Enter it in settings
6. Test - should work immediately

## Why This Happens

SMS Online GH requires sender IDs to be:
- Pre-approved by their team
- Registered to your account

You cannot use random sender IDs - they must be approved first.

   Sender ID: 1234
   ```
