Octopus Group is plotting a move to launch a mobile network service in the UK.

The company, which has had success in the energy sector, is keen to explore opportunities in the telecoms sector, reports The Telegraph.

Such a move would see Octopus create a mobile virtual network operator (MVNO) instead of a mobile network.

An MVNO is a mobile network carrier that offers services without owning its network infrastructure. Uswitch estimates that MVNOs account for more than 10 percent of all mobile users globally.

Its mobile service would instead piggyback off an existing network operator such as EE, O2, Vodafone, and Three, the latter two of which are poised to merge.

The Telegraph reports that Octopus has approached at least one of the major networks through Fern Trading, a subsidiary that owns a handful of telecoms assets.

The newspaper claims the Octopus discussions are believed to be linked to Y Corporation, a mobile company owned by Fern Trading that has a wholesale agreement to use Three’s network.

Y Corp previously launched a beta eSIM MVNO service late last year through its Ymobile service before the company’s website vanished, noted ISP Review.

In January, Octopus appointed Adam Dunlop, the former TalkTalk consumer boss, as a director to explore opportunities in the mobile sector. Dunlop has experience in the MVNO space, previously as managing director at iD Mobile.

Founded in 2000, Octopus Group is best known for Octopus Energy, which it launched in 2015. The company serves around 13 million customers in the UK.

The group has since expanded into a number of different sectors through its investment arm, which manages funds of roughly £10 billion ($13.34bn) for more than 63,000 investors.
