Keeping your old device?

To use an existing dongle or tablet with our network, you need to make sure that your device is compatible and unlocked.

Check compatibility.: Three SIMs will only work with 3G or 4G phones. To check if your device meets the minimum requirement, text 'Mobile' to 78333. (There is no charge for this service)
Make sure your device is unlocked.: If you bought your device from another network, you may need to get it unlocked before you can use it with a Three SIM. Find out how to get your device unlocked so you can use it with a Three SIM.

Understanding your first bill.

Your first bill will be higher than your usual monthly charge, as you'll be charged for a month and up to nine days. This is so you can get connected as soon as you get your phone or SIM. Check out the video for more info. Don't worry if you don't see your device. The video only shows phones, but it works on everything else too.
