No Contract & No Credit Check

With this student offer, you can benefit from the ‘100GB for £10’ deal for 12 months after activation. However, it’s a one-month rolling plan so there’s no contract and no commitment that forces you to stay for the whole of the 12 months. So if things change and you need to switch to another plan or network, you’re welcome to do it.

Another benefit is that there’s no need to undergo a credit check for this deal (unless you’re also buying a handset on credit from giffgaff at the same time). This makes it super quick and easy to sign up, even if you don’t have much of a credit history in the UK.

4G & 5G Coverage From O2

giffgaff is powered by the O2 network – you’ll get both 4G coverage and 5G coverage included as standard.

If you’d like to check the coverage for your home or for your university campus, you can do this by entering the postcode on giffgaff’s online coverage map:

Keeping your Phone Number

Start by ordering your new student SIM from giffgaff’s website. Once you’ve done that, you can ask your current mobile network to give you a PAC Code. This is available through your mobile network’s website or app, or by texting PAC to 65075.

When you activate your SIM, you’ll need to use your .ac.uk email address to get the student exclusive plan. When you activate it, you’ll also be able to submit your PAC Code. This will schedule the transfer of your phone number (normally for the next working day, as long you submit it before 3pm).
