## Restrictions

**For use in Australia**

- Operate only in bands and with settings that are permitted for your location and application. Check this product’s supported frequencies in the description/specs.
- If you intend to operate outside shared/licence‑exempt conditions (e.g. in other bands, at higher power, with high‑gain antennas, or extended duty cycles), you must have the appropriate authorisation.
 
**For use in other regions**

- Follow the spectrum rules for your country/region and select frequencies and settings accordingly.

A declaration of use will need to be submitted during checkout.

## Description

The SIM7028 NB-IoT HAT is a compact and efficient Raspberry Pi accessory designed for Narrow-Band Internet of Things (NB-IoT) applications. It supports multiple global bands and a wide array of protocols like TCP, UDP, LWM2M, COAP, DTLS, DNS, NTP, PING, HTTP(S), MQTT(S), and TLS/SSL. This HAT is ideal for applications requiring minimal delay, low power consumption, and low data throughput, and is especially suited for IoT projects such as remote metering, asset tracking, remote monitoring, healthcare, and bicycle-sharing.
