How it works
Three steps, one phone call
There's no online checkout and no forms to fill in — the whole process happens on a call with our team.
Tell us what you need
Roughly how much data you get through each month, whether you make a lot of calls, and if you're happy with your current network coverage.
We compare options
Our team talks through monthly SIM-only deals that match what you've told us, explaining allowances and contract lengths in plain terms.
You choose, or you don't
If something suits you, we help you take the next step. If nothing fits, that's fine too — there's no pressure to proceed.
Monthly package types
Find the usage band closest to yours
These are general usage categories to help the conversation get started, not fixed prices. Actual allowances, prices and contract terms depend on the provider and change regularly — your specialist will confirm current details on the call.
A good starting point if you're mostly connected to Wi-Fi and use mobile data for messaging, maps and occasional browsing.
The most common band for people who use their phone regularly through the day, on and off Wi-Fi.
Suits people who stream video, use their phone as a hotspot, or rely on mobile data while travelling for work.
Worth asking about if you don't have reliable home broadband or simply want to stop watching your data allowance.
Figures above are general industry ranges for orientation only and are not a quote. Providers, allowances, pricing and offers change frequently — call 0330 520 2173 for current options relevant to you.
Before you switch
A few things worth checking
Our team will cover these with you on the call, but it helps to think about them in advance.
Contract length
Monthly SIM-only deals are usually rolling 1-month or fixed 12/24-month terms. Check which suits your circumstances.
Network coverage
Coverage varies by area and by which physical network a SIM runs on. Mention your postcode area so we can flag anything relevant.
Credit check
Pay-monthly SIM contracts typically involve a credit check by the provider. A pay-as-you-go SIM may suit you better if that's a concern.
Switching your number
Keeping your existing number when you switch usually means requesting a PAC code from your current provider first.
Roaming & travel
If you travel abroad often, ask about roaming allowances and charges — these differ a lot between plans.
Cancellation terms
Ask what happens if you need to leave a fixed-term contract early, and whether any exit fee applies.

Is Oakfield SIM a mobile network? +
No. Oakfield SIM is a phone-based comparison service. We are not a mobile network operator and we are not affiliated with, or acting on behalf of, any single network brand. We help you compare monthly SIM options and, where relevant, connect you with a provider.

No. The call is a no-obligation conversation. You're free to ask questions, compare options, and decide not to proceed at any point.
Will I need to give my card details over the phone? +
Any card or payment details are only ever taken if you decide to go ahead with a specific provider's deal, and that is handled as part of that provider's own order process, which will be explained clearly on the call.
Do you compare every provider in the UK market? +
No. We compare a range of monthly SIM options from the providers we work with; we don't claim to cover the whole of the UK market. See our Advertiser Disclosure for more detail.
