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.

The prices on this page are sorted by Price Score

To calculate price score we combine price, data amount and contract term into a single number that is sorted in Ascending order. When the price price is the same we use Price (asc) > data (desc) > term length (asc) > offer age (desc) to determine the sort order.
