Superdrug is to launch its own Mobile Virtual Network Operator (MVNO), offering discounted connectivity to members of its loyalty programme.

The service is exclusive to holders of a Superdrug Health and BeautyCard and costs £10 a month for 4GB of data and unlimited calls and texts. Any unused data can be rolled over the following month and if it is used up, then there are top ups on offer.
