Monzo, the UK digital bank, today unveiled details about its move into offering mobile phone contracts, with Monzo Mobile pitching itself as rewarding “staying, not switching” customers.

Built on top of the Virgin O2 network, Monzo Mobile will launch this summer and is offering mobile plans as cheap as £8 a month.

Monzo will hope to be able to cross-sell its mobile proposition to its more than 15m banking customers, as it looks to shake up the mobile industry and offer its banking customers more products.

It will go up against the likes of EE and VodafoneThree while newer entrants like Revolut and Klarna have also made moves into offering mobile services.

Monzo is offering three plans using a digital sim priced £8, £12, and £20 a month, with varying data allowances.
