Discover why thousands of families have already joined Family SIM
Family SIM starts with a 12 month contract on the first SIM, but all subsequent SIMs you add are on flexible 30 day rolling plans.
Meaning family members can join and leave the plan whenever they like.
As the bill payer you can manage the plan yourself, or let others in your plan manage their own SIMs.

Once we have confirmed your claim your card will be dispatched. This could take up to 45 days to arrive.
