Paying Three Too Much?
Let's Fix That.

Three might offer unlimited data — but their overall value isn't always what it seems. When families audit ALL their bills through SaveFirst, they save an average of £35/month — completely free.

Why Families Are Leaving Three

Three markets itself as the unlimited data network — but unlimited data doesn't mean unlimited value. Three's contract prices have risen significantly, and their mid-contract price increases catch customers off guard every April.

Here's what's happening right now:

  • Three applies annual mid-contract price rises of CPI + 3.9% — your bill goes up every year
  • Their network coverage is the weakest of the four UK mobile operators
  • Three's broadband offering uses 5G/4G which is weather-dependent and inconsistent
  • Out-of-contract customers are paying significantly more than new customer rates

"Three kept putting my contract price up every April. By the time it ended, I was paying £20 more than when I signed up. SaveFirst found me a better mobile deal AND saved me money on energy too."

Common Questions About Switching From Three

Absolutely. You have a legal right to keep your number. We handle the PAC code transfer — you don't call Three or do anything. Your number moves seamlessly and there's no gap in service.

With SaveFirst, you don't have to do anything. Send us your current Three bill (a photo on WhatsApp is fine), and we handle everything. Your number stays the same.

Most people don't actually need unlimited data — the average UK user consumes around 6GB per month. We'll find you a plan that matches your actual usage at a much better price. If you genuinely need unlimited, we'll find a cheaper unlimited deal.

Yes, completely free. We're paid by the provider when you switch — you never pay us anything. If we can't save you money, nobody pays anything and you stay exactly where you are.

The Bottom Line

Three isn't a bad network — but you're almost certainly paying more than you need to, especially after mid-contract price rises. Don't pay for unlimited data if you only use a fraction of it.

A free SaveFirst audit takes 2 minutes and covers all your bills. If we can't save you money, you stay with Three and nothing changes. If we can — and most families save £35/month or more — it's all yours.

There's literally no downside. The only risk is waiting another month.
