Official-page snapshot on 25 August 2026

New members must activate the relevant plan during the offer period. Existing members must opt in through the giffgaff app and set it as their current or next plan. The boosted allowance lasts for 18 months from first activation.

warning
Some members already using an earlier promotion on the same tier are excluded. Check eligibility and the effective date inside your account before relying on the headline allowance.

Who should choose the £10 80GB plan

The plan suits regular video, social and occasional hotspot use. It includes UK calls and texts, runs on O2 and includes 5G on compatible devices. EU roaming is capped at 5GB, so the UK allowance is not an 80GB European travel allowance.

  • check_circleGood fit: you have tested O2 at home, work or campus and expect to stay for 18 months.
  • check_circleBe cautious: you have just arrived and have not tested indoor coverage.
  • check_circleProbably unnecessary: you regularly use less than 20GB and value the ability to leave each month.

Compare rolling and unlimited options

The current £10 monthly rolling plan includes 20GB. The contract buys four times the data for the same monthly price, while the rolling plan buys flexibility.

Heavy hotspot users can also compare the promotional unlimited plans: £14/month on an 18-month contract or £20/month rolling. Paying more only makes sense if 80GB is genuinely not enough.

Four checks before committing

    Check real usage

    Review the last three months of mobile-data use on your phone.
  3. 3

    Check eligibility

    Existing members should confirm the opt-in and effective date in the app.
  4. 4

    Check exit costs

    You can change plan level during the term, but leaving early may trigger a termination charge.
