Want the best/cheapest deal? To save the most money, we recommend changing from your current supplier.

You can see from the table that you can switch suppliers but still stay with the same underlying network. People often do this if they get good reception at home or work on a particular network.

If you wish to stay with your current supplier, we recommend you call them directly on their "I'm thinking of leaving" customer service line.
