What happens at the end of a Three 12-month SIM only contract?
Once your 12-month term ends, the plan usually rolls onto a 30-day rolling basis, so you're free to leave with 30 days' notice or move to a newer deal.
It's worth reviewing your plan around the 12-month mark to make sure you're still getting the best value.
Is a Three 12-month SIM only deal cheaper than a 30-day plan?
Generally yes. Committing to 12 months usually unlocks a lower monthly price or a larger data allowance than an equivalent 30-day rolling plan, because you're guaranteeing Three a year of custom.
The trade-off is less flexibility to leave early, so it suits people happy to stay with Three for a year.
