Sure CI
Sure (Jersey) Limited / Sure (Guernsey) Limited / Sure (Isle of Man) Limited · Companies House Jersey/Guernsey/IoM Registries (not UK CH)
Sure provides broadband and mobile to homes and businesses in Jersey, Guernsey and the Isle of Man, and is owned by Bahrain's Batelco.
About Sure CI
For homes and businesses in Jersey, Guernsey and the Isle of Man, Sure supplies both broadband and mobile. Our records list full fibre broadband alongside 4G and 5G mobile, and its website asks you to choose your island before it shows the deals for that island. The site presents Sure mainly as a mobile network for the Channel Islands.
Each island has its own Sure company, registered on that island's register rather than at UK Companies House. Our records show the group is owned by Batelco of Bahrain through Sure International.
Its services are for island addresses, so Sure will not be an option for homes in Great Britain or Northern Ireland.
