Sign up for Sky Mobile

Perhaps you don’t run short on data every month, just the ones where you’ve been out of the office a lot or got debilitatingly addicted to Clash Royale. Then Sky’s Mobile service is well worth a look. Launching this year, the new 4G Sim-only service will allow you to roll unused data over to the next month and keep it for up to three years. As long as you have some restraint, it’s a great solution.
