We’ve got something a bit special for you – our unlimited data plan on an 18-month contract for just £15 a month. That’s a whole tenner off. Every month. For 18 months.
But it’s only around for a limited time, so don’t hang about.
If you grab this plan between 13/8/25 and 4/12/25, you’ll lock in that £15 price for the full 18 months. After that, it goes back to the usual £25.
How do I get it?
Already with us? Nice. Just head to the giffgaff app, log in, tap on ‘Extras’ > ‘Your offers’, and opt in. Boom – sorted.
New around here? Welcome! When you activate your shiny new SIM, just choose the £15 unlimited plan and you’re good to go.
And after the 18 months?
You’ll keep paying just £15 a month for 18 months (as long as you don’t change or cancel your plan). Once the 18 months are up, your plan will roll over to the standard price of £25 a month.
Want to change your plan or cancel after that? No worries – you’re in control.
