# Low Cost Tracker Advanced

{% stepper %}
{% step %}

### Overview

The LCT Advanced 3rd Generation introduces a message-based geolocation system.\
Each geolocation request consumes a defined number of message credits. This model replaces unlimited usage with a controlled consumption system based on subscription plans and message pools.
{% endstep %}

{% step %}

### Subscription Plans

<table><thead><tr><th valign="middle">Plan</th><th>Calls / Year</th><th>Call Day Limit</th></tr></thead><tbody><tr><td valign="middle">LCT- Small</td><td>550/year</td><td>1.5/day</td></tr><tr><td valign="middle">LCT- Medium</td><td>1100/year</td><td>3/day</td></tr><tr><td valign="middle">LCT- Large</td><td>2200/year</td><td>6/day</td></tr><tr><td valign="middle">LCT- XL</td><td>4400/year</td><td>12/day</td></tr></tbody></table>

{% endstep %}

### **Message Policy for New LCT Pricing**

* **Validity & Renewal**\
  Messages are valid for **12 months from the date of device activation**. Upon contract renewal, a new yearly message allocation is issued.
* **No Carry-Over**\
  Any unused messages at the end of the validity period **expire and do not roll over** into the next year.
* **Shared Message Pool**\
  All messages are **pooled at the tenant level**, meaning devices with higher usage can draw from the shared pool, including unused messages from less active devices.
* **Consumption Priority**\
  Message usage follows a defined order:
  1. Device-specific message quota
  2. Available **Message Recharge Packs**
  3. Tenant-level shared message pool

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.g-iot.io/commercial-and-usage-framework/low-cost-tracker-advanced.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
