giffgaff is highly reputed mobile virtual network operator (MVNO) that runs on the O2 network. It is best known for its low cost SIM only deals that include a generous allowance of minutes with unlimited texts and unlimited data for a minimum monthly top-up.

Its manifesto is to keep things simple and affordable. It does this by involving its own users in the sales, marketing and customer service operations, thus keeping costs down and in turn passing back the savings to you: the customer.

Customer Service

In keeping with its strapline: ‘the mobile network run by you’, GiffGaff’s customer service is operated by its own customers who answer your queries and help you out when you’re stuck. You can do it too and are generously rewarded with GiffGaff points, not to mention the satisfaction of helping others.

Another advantage of this approach is that it removes the hassle you typically face when dealing with a big mobile operator. You’re able to get help a lot quicker, you don’t have to wait in long call centre queues, and by helping others you help yourself too.


GiffGaff provides four main SIM only packages, also known as ‘goodybags’. These involve minimum monthly top-ups of £10, £15, £20 and £25 respectively.

Each comes with monthly allowance of airtime, unlimited texts and mobile internet, plus free GiffGaff-to-GiffGaff calls.

You can also pick up a data only ‘gigabag’ package, which gets you select amounts of monthly data usage for your tablet devices.

There are no lengthy contracts or cancellation fees involved. You simply top-up each month and reap the rewards.


GiffGaff operates on O2’s network. That means you enjoy the same extensive signal coverage with 3G internet access available to more than 80 per cent of the UK population.
