Introducing life changing broadband in Castlebar

ESB and Vodafone have joined forces to bring you SIRO. Powered by light, SIRO’s 100% fibre broadband will deliver speed, reliability and instant access. This is life changing broadband that uses the existing electricity network. It will revolutionise life in regional Ireland in the same way electrification did over 70 years ago.

SIRO fibre will be delivered using ESB electricity infrastructure in an efficient manner. Some on-the-ground construction work will be involved to deliver the network, however, disruption to the town will be minimal.

SIRO is available soon in Castlebar from Vodafone and Westnet.
