APN Internet SettingsWhat Is the giffgaff Golden £35 Plan?
The giffgaff £35/month SIM only deal is the top-tier plan for heavy data users who want maximum data allowance at a competitive price. At £35/month you choose between two options:
- PAYG: 200 GB data — for users who want a massive one-off monthly bundle with no commitment.
- Rolling Monthly: Unlimited data — the most popular choice, auto-renews every month with no cap on data usage.
Both options include unlimited UK calls, unlimited UK texts, 5G at no extra cost, EU roaming (5 GB), and Wi-Fi hotspot tethering. No credit check required.
Unlimited Data Plan vs 200 GB PAYG
The Rolling Monthly Unlimited plan is the flagship option at £35. If you stream regularly, work from your phone, use your SIM as a mobile hotspot, or simply don't want to worry about data, this is the plan for you.
The PAYG 200 GB option suits users who prefer not to commit to a recurring payment. You buy the 200 GB bundle when you need it and it lasts 30 days. If you don't use it all, the unused data expires — there's no rollover.
Tip: For most heavy users, the Rolling Monthly Unlimited at £35 is the better value — you get unlimited data for the same price as 200 GB PAYG, plus the convenience of auto-renewal.
Who Is the £35 Plan For?
The £35 plan is ideal if you:
- Stream video, music, or podcasts on mobile data regularly.
- Work remotely and use your phone as a Wi-Fi hotspot for your laptop.
- Travel frequently within the UK and rely heavily on mobile data.
- Want complete peace of mind — never worry about data limits again.
- Want the best giffgaff plan without a long-term contract.
5G and Network Coverage
giffgaff runs on the O2 network, which covers 99% of the UK population. 5G is included at no extra cost on all plans, including the £35 plan.
To access 5G, you need a 5G-compatible device and to be in a 5G coverage area. You can check O2's coverage map at o2.co.uk/coveragechecker.
Good to know: Even outside 5G areas, you'll seamlessly fall back to 4G LTE, which is more than enough for HD video streaming and fast browsing.
