Rolling Monthly Business Lines vs 24 Month Carrier Contracts

Rolling monthly business lines let you cancel a line or move it to another plan in any month. Unlike 24 month carrier contracts, there are no fixed annual price rises, which on EE, O2, Vodafone and Three add around £2 a month ex VAT each year.
How do 24 month contracts work?
Lines are locked in for two years, usually with annual price rises built in, and changes mid term are costly.
How do rolling business lines compare?
Cancel or change plan any month. ZIM UK plans range from £4.50 a month for 1 GB to £15 a month for unlimited, all with unlimited UK calls and texts.
