What is a SIM-only deal?

Our SIM-only deals give you a chunk of data, minutes and texts for a monthly cost. You can change each month, or stick with what’s working for you. It’s up to you.

Why switch to a giffgaff SIM-only deal?

Great value, great coverage and great service. We provide great mobile coverage for over 80% of the UK population. Plus all of our SIM-only deals include data roaming in the EU, which means no extra charge while you’re on holiday soaking up the sun.

Our SIM-only plans are designed to give you the flexibility and freedom to change your plan month to month. We don't tie you down to a lengthy contract so you can stay because you want to, not because you have to.

Why should you change over to a SIM-only plan?

SIM-only plans are ideal for those who like a little more flexibility. Don’t get stuck signing up for a 24 month contract. With a SIM-only deal you can change every month if you want. Perfect if you’re not sure how much data or how many minutes and texts you’ll be using.

Which SIM size do I need?

There are three SIM sizes to choose from. Standard SIM, micro SIM and nano SIM. Most newer phones take a nano SIM, while the majority of older phones take a micro SIM. Some non-smartphones do still take a standard SIM though. Our awesomely-designed triple SIM means that it will fit any phone, whether you need a standard, micro or nano SIM.

Can I keep my current mobile number?

Of course. Give your old network a ring and ask for a PAC code (Porting Authorisation Code). Then use our transfer form. Submit the code, choose a date for the transfer and bing, bang, boom. Your current number is moved over.
