Queclink GL53MG Plus

Queclink GL53MG Plus — Micro-Sized LTE Cat M1 Covert Asset Tracker with 4-Year Battery

The Queclink GL53MG Plus is the upgraded LTE Cat M1 and NB2 version of Queclink's proven GL50MG — one of the most compact and long-life covert asset trackers available. Integrating the latest low-power wide area network standards for broader global IoT coverage than its predecessor, the GL53MG Plus delivers up to 4 years of standby time from its 4,400mAh lithium manganese dioxide battery — all in a micro-sized 64.6 x 51.0 x 28.3mm form factor that enables truly covert installation in vehicles, assets and equipment where standard trackers cannot be hidden.

A programmable button adds significant practical value — configurable as a status check trigger or emergency alert button, it allows drivers or operators to instantly send an alert or check device status without any technical knowledge. BLE 5.2 extends wireless accessory connectivity, and three intelligent operating modes — Power Saving Mode, Continuous Mode and Automatic Mode Switching — allow the device to intelligently balance battery life against reporting frequency based on asset activity, maximising operational lifetime without manual intervention.

As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the GL53MG Plus directly from our London warehouse — with trade pricing available for SVR specialists, auto finance companies, asset managers and resellers.

GL53MG Plus vs GL50MG — Which Should You Choose?

The GL53MG Plus is the direct LTE Cat M1 and NB2 upgrade of the GL50MG. Both share the same micro-sized covert form factor and ultra-long battery life. The GL53MG Plus upgrades connectivity from 2G to LTE Cat M1 and NB2 for broader global network coverage — particularly valuable for international deployments in the US, Canada, Australia and other Cat M1 markets — and adds BLE 5.2 for wireless accessory support. For new deployments the GL53MG Plus is the recommended choice.
