Data calculator

Find out exactly how much data you need to purchase with the handy, free day calculator, so you’ll never end up paying more than you need for data. Answer the quick 5 questions and in seconds your recommended plan will appear, listed cheapest first.

Choice a giffgaff goodie bag

Pick the plan that is perfect for you, so you don't have to worry about wasting any money on added extras that you don't need. All plans come with unlimited UK calls and texts, and then from there you can choose how much data you think you'll use and any other added elements you would like to include. There are plans for everyone. If you only use the internet a small amount and go for £6 500MB plan, or if you are always streaming films, the £25 always-on data plan may be right for you, you'll never pay more than you have to.

Check your coverage

Ensure that you'll get great coverage when using a giffgaff service by checking your coverage before you buy using the free coverage checker tool. Enter your town or your postcode and check how good your coverage will be where you live.

Data boost

Once you've bought your third goodie bag with giffgaff, you'll be boosted an extra 1GB of data for free the next time you run out. It's never fun to run out of data, which is why the company has you covered with this handy little perk.
