Our 12GB and 24GB pre-loaded data SIM cards offer great coverage and cost effective data. Simply place the SIM card into your Roam and you can immediately begin to use it.
When you have used all the data, just add more using the Three website or replace with another pre-loaded data SIM. These SIM cards can also be used in many other countries at no extra cost but there are limitations. For full details of these limitations, please contact Three.
