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.

Frequently Asked Questions

How long does the GL53MG Plus battery last?

The GL53MG Plus provides up to 4 years of standby time at one report per day, up to 480 days at 4 reports per day and up to 16 days at 5-minute reporting intervals. The lithium manganese dioxide non-rechargeable battery is designed for the device's full operational lifetime — when depleted the device would need to be replaced.

What is Automatic Mode Switching?

Automatic Mode Switching intelligently transitions the GL53MG Plus between Power Saving Mode and Continuous Mode based on asset movement — automatically increasing reporting frequency when movement is detected and reducing it when the asset is stationary. This maximises battery life without compromising tracking quality during active periods.

What does the programmable button do?

The programmable button can be configured as a status check trigger — pressing it causes the device to immediately send a status report confirming GPS position and device health — or as an emergency alert button that instantly sends an alarm to the monitoring platform. This is particularly useful for drivers or operators who need to quickly check the device is working or send an emergency notification.

Does the GL53MG Plus require a SIM card?

Yes — the GL53MG Plus requires a SIM card with LTE Cat M1 or NB2 capability and 2G fallback. It is not supplied with a SIM. Contact us for SIM recommendations for UK and international asset tracking deployments.

Can I buy the GL53MG Plus in bulk from Tracking Hardware UK?

Yes — we supply SVR specialists, auto finance companies, asset tracking operators and resellers across the UK and internationally. Volume pricing and trade accounts are available. Contact us for a bulk quote.

Does the GL53MG Plus support driver identification?

The GL53MG Plus is a long-life battery asset tracker with no external wiring, so driver identification readers do not apply to it. For vehicles, pair a hardwired Queclink tracker such as the GV57MG with an iButton reader — Tracking Hardware UK supplies both.
