Giffgaff SIM only deals are available for 30-days and 18 months. Find the best Giffgaff SIM only deals for you.
Why choose Giffgaff's 18-month plan over a rolling monthly SIM?
Giffgaff's 18-month goodybags lock in a set allowance and price for the duration, which can work out cheaper per month than its rolling deals and protects you from mid-term price changes.
It suits people who know their usage and want a steady bill, rather than those who like to switch frequently.
Can I leave a Giffgaff 18-month plan early if my needs change?
Giffgaff's 18-month plans are a genuine commitment, so leaving early may mean paying off the remaining months, unlike its no-contract 30-day goodybags.
If you're unsure how long you'll stay, the flexible monthly option may be the safer choice even if the headline price is slightly higher.
