01

What giffgaff is known for

giffgaff’s core strength is simple, low-cost mobile service: month-to-month “goodybag” bundles, pay-as-you-go credit and a lightweight online account. They also run a modest shop with unlocked and refurbished phones — not a full carrier phone portfolio, but enough if you want an unlocked handset without a long contract. Support is community-driven rather than large phone centres.

How to get the best price

For the cheapest per‑GB cost, match a goodybag to your typical monthly use and change it the next month if needs shift — you’re not tied in. Watch the giffgaff shop around Black Friday and other sale periods for handset drops; compare those flashes with wider-market prices and cashback sites. Also consider PAYG top-ups if you use the phone sporadically.
