Zest4

Zest4 connectivity expertise and Vision guidance help organisations connect, manage and monitor business-critical devices.

Connectivity Built For Devices

Specialist IoT Expertise

Founded in 2013, Zest4 is a UK wholesale communications provider supporting more than 500 partners. Its portfolio spans mobile, unified communications and connectivity, with a dedicated IoT offering for devices and machine-to-machine communication.

Choice Across Networks

UK And International Coverage Options

Zest4 is mobile-network-operator agnostic, providing single-network and multi-network options alongside roaming and international connectivity. This allows services to be considered around where devices operate and how they exchange information.

Managed Through Vision

Connectivity Shaped Around The Application

Vision begins with the devices, locations, expected data use and remote-access requirements. We then work with Zest4 to assess suitable networks, tariffs and management options, with clear support arrangements as the deployment develops.

Application-Specific Connectivity

Connectivity can be selected around the needs of sensors, cameras, tracking devices and other equipment rather than treated like an employee mobile service.

Multi-Network Choice

Single-network and multi-network options allow coverage and resilience to be assessed against the locations where each device will operate.

Central SIM Visibility

Zest4 Connect provides usage information and reporting across a SIM estate, supporting cost management and investigation of unexpected consumption.

Controlled Remote Access

Fixed IP addressing and VPN options can support applications that require managed remote access to connected equipment.
