# Auto-Disable function

## Auto-Disable Functionality for High-Usage SIM Cards

The Auto-Disable function is available exclusively for high-usage SIM cards (Green profile). It is designed to help you control costs by automatically disabling your SIM at the end of the calendar month.

## How it works

When the Auto-Disable function is enabled:

* Your SIM will automatically disable between 21:00 and 00:00 UTC on the last day of the calendar month.
* This means your SIM may stop working up to 3 hours before midnight UTC.
* The SIM will remain disabled until you manually re-enable it in the next month (and optionally re-enable Auto-Disable again).

## Requirements

* The Auto-Disable function can only be enabled if your SIM is currently enabled.
* If the SIM is not yet enabled, first enable it to see the Auto-Disable toggle.
* If you manually disable your SIM after enabling Auto-Disable, the Auto-Disable setting will be cleared. You’ll need to enable it again if you re-enable the SIM later.

## Timing

* The Auto-Disable function is triggered only by time, specifically in the window between 21:00 and 00:00 UTC on the last day of the calendar month.
* It does not activate when your data bundle is used up

## Example

You enable your high-usage SIM on June 16th. The system calculates the remaining days in June and charges you proportionally:

* 15 days remaining / 30-day month = 50%% of the plan
* You receive 5 GB, and $5 is deducted from your balance

If you activate the Auto-Disable functionality, your SIM will be disabled automatically between 21:00 and 00:00 UTC on June 30th, avoiding unexpected charges on July 1st.

## Best Practices

* Enable Auto-Disable early in the month if you want to avoid rolling into the next month unintentionally
* Keep in mind that manual disable actions remove the Auto-Disable setting
* Use this feature to stay in control of costs, especially if the SIM is used in devices without direct monitoring.
