Best Sim Only – Data/Internet Plans
The plans listed below are Sim Only. This means no contract but there is a month to month arrangement where your credit card or bank account (if they allow it) will be charged each month that you choose to stay on the program. Sim Only offers in many cases better value than prepaid. The mobile data plans you will see below are very good value, particularly if you have just purchased a smart phone or are looking to use your existing mobile phone to surf the world wide web (or social network services such as Facebook or Twitter). The table below compares what is on offer from each provider, the increments that the data is counted by and how much additional data will cost. “Connection” attempts to show how many times you can access the internet (even if the download/upload is 1KB) with 1GB data.

The key consideration regarding data increments is how the rounding is applied when your data session is closed (by you or the network). Where increments are p/MB, this means that when the data session closes your data for that session will be rounded up to the nearest MB. So if in that session you’ve consumed 8.6MB, this will be counted as 9MB, if you’ve consumed 0.1MB this will count as 1MB. This is where p/KB can make a difference. Where you have consumed 8.6MB, you will actually on be charged for 8.6MB, where you have used 100KB (or 0.1MB) that is all you will be charged.
