Business Mobile, Data & IoT Connectivity
Reliable mobile connectivity for your people, premises and equipment. Business mobile SIMs, data-only SIMs and IoT/M2M connectivity for businesses, remote equipment and connected systems — supplied and managed by Omni3 across West Sussex and the South East.
Omni3 is a business technology and infrastructure provider. We supply connectivity for people, premises, equipment, remote sites and connected devices — as part of a wider technical solution rather than simply selling SIM cards. Business mobile, data SIMs and IoT connectivity sit alongside our electrical, solar, EV charging, security, data networking and hosted telephony services.
Connecting your people, premises and equipment
Mobile connectivity requirements vary significantly depending on what is being connected. A business mobile phone for an employee has different requirements from an IoT SIM inside an EV charger. A data SIM providing broadband backup has different requirements from a SIM inside an alarm communicator. Omni3 can advise on the right connectivity for the application rather than applying a single solution to every requirement.

Access to all four major UK mobile networks
Omni3 can provide mobile, data and IoT connectivity across the UK's four major mobile networks — EE, O2, Vodafone and Three. This means we are not restricted to recommending a single network for every customer or every application.
Mobile coverage can vary significantly from one location to another. A network that performs well at a city-centre office may not necessarily provide the strongest connection at a rural CCTV site, EV charger, construction site or remote monitoring installation. Because Omni3 works with all four networks, we can consider the connectivity requirement and location before recommending the most appropriate service.
For IoT and M2M applications where resilience matters more than operator preference, network-agnostic SIMs and multi-network SIMs are also available — connecting to whichever network provides the best signal at the installation location.
Single-network SIMs
SIMs provisioned specifically on EE, O2, Vodafone or Three — selected based on coverage, data requirements and commercial suitability for the specific application and location.
Multi-network / network-agnostic SIMs
Specialist SIM solutions capable of connecting to multiple available networks where supported by the selected service — providing additional resilience for IoT, M2M and remote equipment.
The right network for the location, rather than forcing every installation onto the same network. Where coverage at a specific site is a concern — for remote monitoring, CCTV, alarm signalling, EV chargers or broadband failover — we advise on the most appropriate network or SIM product before provisioning.
Business Mobile SIMs
Omni3 provides mobile connectivity for businesses requiring individual or multiple mobile connections. Business mobile SIM services are managed through a single account with centralised billing — suitable for sole traders, small businesses and organisations requiring mobile connectivity for teams of any size.
As part of our wider connectivity offering, business mobile sits alongside business broadband, hosted telephony, data networking and Wi-Fi — one supplier for all your communications services.
Business SIM-only plans
SIM cards for business mobile phones — voice, text and data — without tying you to a specific handset. Suitable for staff who use their own device or where a business SIM is needed on an existing phone.
Multiple users and centralised billing
Multiple business mobile connections managed on a single account with centralised billing. One invoice covering all your mobile connections rather than individual consumer contracts.
Pooled and shared data
Data pooling across multiple SIMs on the same account. Unused data on one SIM is available to others in the pool — reducing overage charges and simplifying plan management.
Number porting
Existing business mobile numbers can be transferred to Omni3-managed SIMs. We manage the porting process, which typically completes within one working day.
eSIM
eSIM provisioning where supported by the device. Removes the need to physically handle a SIM card — useful for remote device activation or devices with restricted SIM slot access.
UK and international roaming
Roaming options for staff who travel internationally. We confirm applicable roaming terms and supported regions at the point of sale.
Mobile for field and remote staff
Reliable mobile connectivity for employees working away from the office — engineers, field teams, site staff or staff working from home or at client premises.
Handsets and devices
Business mobile handsets supplied with SIM service where required. Devices can be provisioned and supplied as part of the same account and contract.
4G & 5G Business Data SIMs
Internet connectivity without a fixed line. A 4G or 5G data SIM provides internet access through the mobile network — without requiring a traditional fixed telephone line or broadband connection. Data SIMs are supplied in standard form factors for insertion into routers, devices and equipment.
Where the application requires a router, network or Wi-Fi system alongside the data SIM, Omni3 can supply and configure the complete solution. As a DrayTek Approved Partner, we install and configure DrayTek business-grade routers alongside the connectivity they carry.
4G and 5G routers
Insert a data SIM directly into a 4G or 5G router for internet connectivity without a fixed telephone line or broadband circuit.
Construction sites and site offices
Temporary internet connectivity at sites without permanent infrastructure. A data SIM provides reliable connectivity while the project is active.
Tablets and laptops
Mobile data connectivity for devices used in the field, on the road or at locations without reliable Wi-Fi.
Mobile CCTV
Data SIMs for mobile or temporary CCTV installations where a fixed internet connection is not available.
Broadband backup
A data SIM installed in the router provides automatic internet failover when the primary broadband connection fails.
Remote premises
Buildings or locations without access to fixed-line broadband — outbuildings, agricultural premises, remote offices or temporary facilities.
Events and temporary installations
Short-term internet connectivity for events, exhibitions, pop-up locations and temporary deployments.
Remote equipment
Providing data connectivity to equipment that needs an internet connection but is installed away from fixed network infrastructure.
Data SIM with router, network and Wi-Fi
A data SIM alone is often not enough. Omni3 can supply the SIM alongside a professionally configured DrayTek router, local area network and Wi-Fi system — so the connectivity is properly configured for the application from day one.
IoT & M2M SIM Cards
An IoT SIM (Internet of Things SIM) — also referred to as an M2M SIM (Machine-to-Machine SIM) — is a SIM card designed for use in connected devices and equipment rather than mobile phones. IoT SIMs allow equipment to communicate over the mobile network without depending on a local broadband connection.
IoT SIMs are used in a wide range of applications: CCTV systems, alarm communicators, EV chargers, solar inverters, asset trackers, environmental sensors, payment terminals and any connected device that needs reliable data connectivity at a fixed or remote location.

Multi-Network IoT Connectivity
A standard SIM is locked to a single mobile network. If that network has poor coverage at a particular installation location, the device loses connectivity — which is a problem for always-on equipment such as CCTV systems, alarm communicators, EV chargers and remote monitoring.
Multi-network SIMs and network-agnostic SIMs are available depending on the application and service selected. For suitable IoT and M2M applications, these specialist SIM solutions can connect to whichever network provides the best available signal at the installation location — rather than being fixed to one operator.
Network-Agnostic SIM Connectivity
For applications where resilience and coverage matter more than being tied to a particular mobile operator, Omni3 can provide network-agnostic SIM solutions. These are designed to connect using the best available network rather than a fixed operator — improving availability in remote, rural or variable-coverage locations.
Network-agnostic SIMs and multi-network SIMs are particularly relevant for IoT devices, M2M communications, CCTV systems, alarm signalling, EV chargers, remote monitoring, asset tracking and 4G/5G broadband failover — wherever connection stability matters more than the choice of operator.
Multi-network roaming
Connecting to whichever available network provides the best signal at the installation location.
Remote SIM management
Configuration and management of SIMs without physically accessing the device.
Usage monitoring and alerts
Data usage tracking with configurable alerts and spending controls.
Private APN
Private network access point for applications requiring secure, isolated connectivity.
Fixed IP address
Static IP addresses for applications requiring inbound connections or consistent addressing.
Central management portal
Visibility and control of all SIMs from a single management interface.
Important: Not every SIM Omni3 supplies is automatically multi-network. Single-network SIMs are provisioned on a specific network chosen for the application. Multi-network and network-agnostic SIM solutions are available for suitable IoT and M2M applications — we confirm which product is appropriate during the requirements discussion.
4G & 5G Backup Internet for Business
A broadband outage can disrupt cloud services, VoIP telephone systems, payment terminals, CCTV, remote access and any business application that depends on an internet connection. Broadband failover using a 4G or 5G SIM provides automatic backup connectivity when the primary connection fails.

Complete connectivity from one supplier
Omni3 can look at the complete connectivity requirement — primary broadband, router, local network, Wi-Fi and 4G/5G mobile failover — as a single programme. Managing the entire stack through one supplier means the failover is configured correctly with the router and primary connection, with one point of contact if something goes wrong.
Connectivity designed around the application
We don't simply supply connectivity. We help determine what the connection actually needs to do.
A CCTV system has different connectivity requirements from a mobile phone. An EV charger has different requirements from a tablet. A remote monitoring system may require different resilience, IP addressing or data usage from a standard business mobile.
Our advantage is understanding the equipment the SIM is being used with. Because Omni3 installs CCTV systems, EV chargers, solar and battery storage, alarm systems and data networks, we understand what each type of connected device actually requires from its connectivity — not just which SIM is cheapest.
Equipment being connected
The type of device determines the SIM type, data profile, power requirements and form factor needed.
Expected data usage
A CCTV stream has very different data requirements from an alarm communicator or an asset tracker.
Signal and coverage
We consider network coverage at the installation location before provisioning — particularly important for rural or remote sites.
Network resilience
Applications that must stay connected benefit from multi-network or network-agnostic SIM solutions rather than a single-network SIM.
Router and antenna selection
The right SIM in the wrong router or without an appropriate antenna may not perform as expected. We consider the complete installation.
Fixed IP and remote access
Where inbound connections or remote management are needed, we configure static IP addressing and private APN as part of the service.
Integration with existing networks
SIM connectivity that needs to communicate with an existing on-premises or hosted network is designed to integrate correctly.
Cybersecurity
Connected devices on mobile networks face the same security risks as devices on fixed networks. We consider appropriate segmentation and access controls.
Ongoing support
As the supplier for both the connectivity and, in many cases, the equipment itself, Omni3 can provide joined-up support across the installation and its connectivity.
