Fiver vs giffgaff
Fiver vs a giffgaff goodybag
giffgaff's goodybags are a fair deal and there's no contract, but they're monthly and they need a physical SIM ordered, posted and activated — which is no use at all when you've run out of data on a Tuesday and payday is Friday. Fiver is the four-day version: an eSIM, live in minutes, gone when your next reset arrives.

giffgaff sells monthly 'goodybags' of data, minutes and texts on O2's network, with no contract and the option to change bag each month. New members order a SIM and activate it; eSIM is available on supported handsets. Prices change with their current bag line-up.
What running out costs
Fiver is one price: £5.00 for 5GB, however long you're short for. Their prices were read off their own site on 2 August 2026.

When giffgaff is the better buy
- You want a proper main SIM with calls and texts, not a bridge. That's what goodybags are for and they do it well.
- You've got time to wait for a SIM and you're switching networks anyway.
- Your data problem is every month, not this month.

Common questions
- Can I get a goodybag today if I've run out of data?
- Only if you're already a giffgaff member, or your phone supports their eSIM. Otherwise there's a SIM to order and wait for — which is the gap Fiver exists to fill.
- Is Fiver a replacement for giffgaff?
- No, and we don't want to be. Fiver is data-only and lasts days. If you need a main line, giffgaff is a better answer than us.
- Do I keep my number with Fiver?
- Yes. Fiver never touches your number — it's a second, data-only line on your phone.
- What does Fiver cost compared to a goodybag?
- Less, for a few days — because you're buying a few days. More per gigabyte over a month, which is why we cap sales at 14 days.
