# How to Schedule SMS Messages

The **Schedule SMS** feature allows you to compose messages now and have them sent automatically at a specific date and time in the future. This is perfect for reminders, appointments, marketing campaigns, or any message that needs to be sent at a particular time. This guide covers scheduling SMS on both iOS and Android.

## Prerequisites

Before scheduling SMS, ensure you have:

- ✅ SMSGatewayCenter app installed and logged in
- ✅ Sufficient account balance (charged when message is sent, not when scheduled)
- ✅ Recipient phone number(s)
- ✅ Message content ready
- ✅ Desired send date and time

## Understanding Scheduled SMS

### How It Works

1. **Compose Now**: Write your message and set send time
2. **Save Schedule**: Message is saved and scheduled
3. **Automatic Send**: App sends message at scheduled time
4. **Delivery Reports**: Receive reports when message is actually sent

### Benefits of Scheduling

✅ Perfect Timing: Send messages at optimal times
✅ Time Zone Management: Schedule for recipient's local time
✅ Batch Preparation: Prepare messages in advance
✅ Automation: No need to remember to send manually
✅ Campaign Planning: Plan marketing campaigns ahead
