More About eir
EIR operates as a nationwide telecommunications carrier in Ireland, with a portfolio that spans fixed-line broadband, mobile connectivity, and voice services for both consumer and enterprise environments. For technical and infrastructure stakeholders, EIR functions as an access, aggregation, and transport provider, offering last-mile and backbone connectivity that underpins enterprise WANs, internet access, SIP-based voice, and mobile data services.
On the fixed side, EIR provides broadband services over a mix of copper, fiber-to-the-cabinet (FTTC), and fiber-to-the-premises (FTTP) architectures (network connectivity). These services use standard IP networking, Ethernet, and broadband protocols and are often integrated by enterprise customers into Software-Defined Wide Area Network (SD-WAN), Virtual Private Network (VPN), and hybrid cloud topologies. Organizations use EIR’s fixed access for primary or redundant internet access, site-to-site connectivity, and as underlying circuits for managed network and security solutions provided either by EIR or by third-party integrators.
In mobile, EIR operates a cellular network that supports voice, Service Mesh Security (SMS), and packet data services (mobile connectivity). Enterprises and public bodies make use of mobile subscriptions, mobile broadband, and data-only SIMs for distributed workforces, Internet of Things (IoT) endpoints, and field operations. EIR’s mobile services interoperate with standard device platforms and are typically managed through common enterprise mobility management and MDM frameworks.
For voice and collaboration, EIR offers fixed voice services over both legacy and IP-based infrastructures, including Session Initiation Protocol (SIP) and VoIP-style capabilities (unified communications). Business users can integrate eir-provided voice trunks with on-premises (on-prem) PBXs, cloud telephony platforms, or collaboration suites to support inbound and outbound calling, contact centers, and internal telephony. These services rely on standard telephony protocols and interconnect arrangements with other national and international carriers.
EIR also maintains a wholesale division that provides access to its fixed and mobile network infrastructure for other operators and service providers (wholesale connectivity). This includes bitstream and other regulated wholesale products on the fixed network, as well as roaming and interconnect services on the mobile side. In this role, EIR’s infrastructure acts as an underlying layer for multiple retail brands and virtual operators active in the Irish market.
Within an enterprise IT and procurement directory, EIR aligns to categories such as network and Internet Service Providers (ISP), Mobile Network Operators (MNOs), unified communications and voice services, and wholesale carrier services. Its offerings are typically evaluated alongside other connectivity providers when organizations design Wide Area Network (WAN) architectures, choose internet access partners, or source mobile and fixed voice services to support applications, collaboration platforms, and cloud workloads.
