The sun is setting on 2G and 3G, are your hatch protection systems 4G ready?

As of April 1st 2023, all new Watercress 4 systems will come with 4G modems installed as standard.

New 4G capable systems will enable a smooth and hassle-free transition to the 4G network, allowing our clients to upgrade their SIM provisioning prior to the 2G/3G sunset, saving valuable time and resources.

All newly supplied systems and replacement PCBs remain backward compatible with legacy 2G/3G networks and SIM cards, whilst those networks are still active.

We have a number of options available to clients currently using older generation Watercress systems which will require an upgrade prior to the expected 2G/3G sunset.

For more information, please contact us at or call 01934 743440.
