We offer all the perks of a traditional mobile contract but with none of the hassle that comes with long-term commitments. These packages are designed to replicate the reliability of a contract while giving you the freedom to adjust your plan to suit your needs. Whether you want to switch to a different tariff, cancel your plan, or let it renew automatically, giffgaff ensures you’re always in control.

Unlike traditional contracts, our tariffs are paid upfront, so you’ll always know exactly what you’re spending. This means no hidden fees or surprise bills, making it easier to manage your budget. Each package is valid for 30 days from the activation date, giving you the flexibility to reassess your plan month by month.

Whether you’re a heavy data user, prefer unlimited calls and texts, or want a balanced combination of both, giffgaff has a plan for you. It’s an ideal solution for anyone who values simplicity, reliability, and adaptability. With giffgaff, you get a contract-like experience that you can adjust to your lifestyle, giving you the freedom to enjoy convenience without being tied down.

A monthly plan can be used in the EU and selected destinations in the same way you would in the UK and at no extra cost. This means you will be able to make unlimited calls and send unlimited sms to United Kingdom and also to any other EU country and selected destinations at no extra cost. Although you can only use up to 5GB of your goodybag allowance while roaming. Beyond this, there’ll be a charge of 10p/mb while you are out of the UK borders.

If you choose to use your balance rather than a monthly plan, your data, calls, and text messages will be charged according to our international rates.

However, if you’re travelling outside the EU and to certain destinations, check out our roaming costs. You’ll have to add credit to your account to use your phone as normal. Happy travels.
