How to choose between giffgaff and SMARTY student plans (2026)

Separate a student promotion from a plan students can buy

On 12 September 2026 SMARTY's homepage listed: unlimited £20, 200GB £17, 150GB £15, 100GB £12, 40GB £10, 20GB £9, 16GB £8 and 5GB £6. The same homepage was also promoting 32GB for £8 as a double-data offer. Those figures change. Use the live plan page at checkout.

Do not treat third-party posts that claim "50GB or 80GB for £8" as a fact. That is not what SMARTY's homepage showed that day. Searches for giffgaff student plans should land on this student-promotion comparison, not the ordinary £10 three-way table.

Choose giffgaff when you can prove student status and need predictable general data

The 100GB on the giffgaff student promotion is all general data. Hotspot, maps, video calls and browsing come from the same allowance, which is easier to budget.

Existing members can join. The student-offer help page says: register with a .ac.uk email if you have one; if you already have an account, change the email there. After you save it, check whether the £10 / 100GB student plan actually appears. The detailed workflow is in the giffgaff student application guide.

The bar is higher. Without a working .ac.uk inbox or a designated student SIM, do not plan around 100GB. The 12-month benefit starts when the plan first goes live. Turn auto-renew off and later months may lose the offer. Indoor O2 signal in your room, lecture theatres and commute matters more than the extra data on paper.

Choose SMARTY when the university email is not ready and you want a one-month trial

SMARTY's student page repeats the same points: one-month rolling, pause or cancel, no credit check, 5G, hotspot allowed. That is the more direct path if you have just arrived, do not have a hall address yet, or the .ac.uk inbox is still closed.

The EU allowance is also wider. Official text allows up to 12GB from the plan, plus calls and texts to UK numbers while in the EU. For weekend trips, that can matter more than 20GB extra in the UK.

It is not a student-only 100GB plan. If you compare against giffgaff's 100GB, use SMARTY's live £10 or £12 tiers, not the marketing sentences. On 12 September 2026 the £10 tier was 40GB and the £12 tier was 100GB. The £8 tier was 16GB as standard, or 32GB during the double-data promotion.

SMARTY also says the service is 4G / 5G and is not compatible with 2G handsets. Check old phones first. Official roaming text says the service may be suspended after 60 days of continuous use outside the UK in a rolling 12-month period.

Decide in four steps, not 100 versus 40

1. 1

   Check eligibility

   Do you have a .ac.uk email or a designated student SIM? If not, do not budget for giffgaff's student 100GB.
2. 2

   Map coverage

   Check O2 and Three coverage for halls, campus and the commute. Test indoors if you can.
3. 3

   Read actual usage

   Use three months of real data. Heavy hotspot or use near 80GB favours the giffgaff student tier. Light or unsettled use favours a SMARTY monthly plan.
4. 4

   Open the live plan pages

   Record price, allowance, renewal date and the cancel path before you pay.

If O2 already works, the email qualifies and you will keep auto-renew on, start with the giffgaff student promotion. If the university inbox is late, you want to test Three, or the 12GB EU cap matters more, start with SMARTY's live public tiers. LarkSIM already has an August £10 three-way comparison for ordinary rolling plans, not this 100GB student promotion.

A physical card is only useful before arrival. A verified giffgaff physical SIM does not grant student eligibility. The VOXI student offer stays on its own giffgaff versus VOXI student comparison.
