4G LTE-M Connection

Zaptec Pro and Zaptec Go are supplied with 4G LTE-M eSIM, as standard, and will connect to the network automatically when they are powered up.

  • The 4G LTE-M eSIM is built-in into the device and is not user-replaceable.
  • You cannot share the LTE-M network with other chargers. 

What is 4G LTE-M?

4G LTE-M is a specialised cellular network designed for devices like your charging station. Unlike regular 4G that is used by cell phones, LTE-M offers better coverage and reliability specifically tailored for machine-to-machine communication.



  • Network Coverage: The charger needs to be in an area with 4G LTE -M coverage for this to work. The Telenor 4G LTE-M network will normally have coverage in all areas that would not normally have regular 4G coverage, but the base station has to be equipped to broadcast LTE-M.
    • Check LTE-M network availability in your area to guarantee reliable connectivity. Use a test device, or a Zaptec charger with 4G activated. Alternatively, check a coverage map provided by the operator.
    • General IoT coverage info can be found here: https://www.gsma.com/iot/deployment-map/
  • Placement: Avoid positioning the charging stations in places where objects may affect coverage. Test the coverage in a variety of situations, such as with the garage door open/closed.
  • Backup Plans: Have alternative communication methods ready in case of LTE-M network issues to ensure uninterrupted charging.

The chargers can operate on 4G LTE-M only (CAT-M1). We are exploring support for 4G NB-IoT, which will provide better coverage in the UK. We do not plan to support 2G/3G. 


4G coverage in the UK

In the UK, 4G -LTE -M coverage is not complete, with about half the country being covered today.
