Giffgaff discounts unlimited everything plan to £15/month
Looking for a way to cut down your monthly phone bill without giving up unlimited data, calls, and texts? Giffgaff has just rolled out one of its most eye-catching offers yet. For a limited time, the network is slashing the cost of its unlimited “everything” plan to nearly half the usual price—making it one of the cheapest truly unlimited deals you’ll find in the UK right now.
Whether you’re a heavy streamer, a constant hotspot user, or just want the peace of mind that comes with never running out of data, this discount could be a game-changer.
What’s the Deal?
- Standard Monthly Rolling Plan
Get unlimited UK data, calls, and texts for £35/month, with 5G access and no contract. - Special 18‑Month Contract Discount
For a limited time, Giffgaff is offering the same unlimited everything plan for just £15/month (down from £25) when you commit to an 18‑month contract.
This promotional price is valid from 13 August to 4 December 2025, locking you in for the full 18 months at the discounted rate.
Announcing the new ‘unlimited everything’ deal, Ash Schofield, CEO at giffgaff, said:
“We’re always looking for ways to improve our SIM plans to make life a little easier for our members, so we’re proud to launch this absolute steal of a deal. Not only that, but while many other network providers increased their prices this year, we stuck to our commitment to no mid-contract price rises, so our members can rest easy that their mobile bill will stay the same for the length of their contract.”
What’s Included in the Unlimited Plan?
- Unlimited UK Data, Calls & Texts — genuinely unlimited with fair use limits.
- O2 Network Coverage (4G and 5G) — enjoy fast speeds where available.
- EU Roaming — includes up to 5 GB of data per month in the EU at no extra cost.
- Plan Flexibility — whether on contract or rolling, you can upgrade or downgrade your plan anytime without affecting your existing contract length.
- No Mid‑Contract Price Rises for contract plans—your monthly fee remains stable.
- Rewards Program — earn £5 Payback for referring friends and for community contributions.
Unlimited—but Are There Any Limits?
- Fair Usage Policy:
While the data is branded “unlimited,” usage that is considered excessive—like using approximately 650 GB in one month, twice in six months—may trigger a review by Giffgaff. - Tethering:
You may tether or hotspot data to other devices, but repeatedly connecting more than 12 devices could draw scrutiny.
Which Plan Should You Choose?
| Plan Type | Monthly Cost | Commitment | Best For… |
|---|---|---|---|
| Monthly Rolling Plan | £35 | None | Short-term flexibility; ideal if you may switch plans soon. |
| 18‑Month Contract Deal | £15 (promo) | 18 months | Long-term value; excellent if you want stable pricing. |
Why opt for the contract deal?
- It’s currently the UK’s cheapest unlimited data SIM with 5G coverage via O2.
- Fixed pricing prevents annual cost hikes.
- Includes EU roaming and tethering, providing convenient extras.
Downsides?
- 18‑month commitment—if you need to cancel early, expect a fee of about 50% of remaining payments.
- A rolling plan remains more flexible for short-term users.
Final Thoughts
- The £15/month unlimited plan is a remarkable limited-time offer—£10 less than the standard contract price of £25.
- If you can commit to 18 months, it’s a hard-to-beat bargain with full UK coverage, rewards, and roaming perks.
- For maximum flexibility with no commitment, the £35 rolling plan still offers great value—just without the promotional price.
