How It Works | Thornfield SIM

You call 0330 059 9027

Calls are answered by our UK-facing advisory team during opening hours (Mon–Sat, 9am–7pm). Standard call charges from your provider apply — there's no premium rate.

We ask about your usage, not your budget first

Rather than starting with a price, we ask how you actually use your phone: roughly how much data, whether you roam abroad, and what you're currently paying. This is what lets us point you at a plan that actually fits, instead of the first one on a list.

We compare live options across networks

Using current pricing and availability, our team talks you through two or three SIM-only options that suit your usage and postcode, including the trade-offs of each — data caps, roaming terms, and contract length.

You choose, or you don't

If one of the options works for you, we can help set the switch in motion, including porting your existing number if you want to keep it. If nothing suits you, the call simply ends — there's no obligation and no pressure.

Your new SIM arrives and activates

If you go ahead, your chosen network handles delivery and activation directly, following their own standard process and terms. We remain a comparison and advisory service — the contract for the plan itself is between you and the network or provider you choose.
