Pay Monthly SIM Only

SIM Only contracts are a great way to save money on your mobile bill. You can choose a contract length between 30 days and and 2 years.  Generally 12 month contracts hit the "sweet spot" of value and flexibility, but 24 months and the newer 18 month contracts are becoming more competitive.
