"Tesco Mobile has launched a new Family Perks initiative, offering bonus bundles of minutes or data to members of the same family.
Families that have two or more Tesco Mobile subscriptions can choose from 500 extra minutes to Tesco Mobile phones, 150 extra minutes to any network, or 250MB of extra data. The MVNO is also offering families one bill for up to five Tesco Mobile postpay or Sim-only accounts under the same address. Family Perks is open to all pay monthly or Sim-only customers with two or more subscriptions on the same account."
