SIM Only plans provide you with a SIM card along with a monthly allowance of minutes, texts and data, but don’t come with a phone. They are a great option when you don’t need a new mobile, allowing you to save money as there is no upfront cost and the monthly outlay will be lower. SIM Only contracts are also usually shorter term than Pay Monthly phone plans, so you’re not tied in for as long.
