24-month SIM only deals
24-month SIM only deals are a great way to save money if you don't need a new phone. We've found the best 24-month SIM only deals available on the market.
Are 24-month SIM only deals cheaper than shorter contracts?
A 24-month SIM only deal often has the lowest monthly price for a given allowance, because the network locks you in for two years in return for a discount.
If you're confident you won't want to switch networks or change your allowance soon, the longer term can be the cheapest way to get the data and minutes you need.
What happens if I want to leave a 24-month SIM only contract early?
Leaving before the two years are up usually means paying an early exit fee, which is typically the remaining monthly charges added together.
If you're unsure how long you'll stay, a 30-day or 12-month SIM only deal gives you more freedom, while a 24-month deal rewards a longer commitment with a lower price.
