Your Pay As You Go SIM card gives you the flexibility of not being on a contract. Once you’ve inserted your SIM and downloaded our Three app, you can add a Data Pack which gives you a month’s worth of data, calls and texts. You have the option to renew each month without being tied into a 12, 24 or 36 month contract.
