Why no single “winner”? A cheap plan with weak coverage where you live is not a deal. We separate shopping routes by use case, mark every commercial link and never sell placement in the editorial order.

Start with your usage
How much data do you need?
Buying the biggest allowance is not automatically good value. Look at your phone's mobile-data history before choosing.
Up to 10GB
Calls, messaging, maps and light browsing—mostly connected to Wi-Fi.
20–50GB
The sensible range for social media, music and occasional video.
100GB+
Frequent streaming, hotspot use or fewer dependable Wi-Fi connections.
Unlimited
Heavy streaming and tethering where you do not want to monitor usage.
Three numbers to check
What leaves your account each month before considering a promotion or price rise.
Useful for comparison, but only if you understand whether cashback is automatic or must be claimed.
The clearest comparison once scheduled price increases and the full commitment are included.
Frequently asked questions
Which partners are linked on this page?
1pMobile, Mozillion, Mobiles.co.uk and WorldSIM. The detailed five-plan snapshot is specifically from Mobiles.co.uk; the provider cards above are separate shopping routes for different needs.
Can I keep my mobile number?
Yes. Ask your current network for a PAC and give it to the new network during the switch. Do not cancel your old service before the number transfer completes.
Should I choose one month or 12 months?
Choose one month when flexibility matters. A longer agreement can unlock more data or cashback, but check price increases and the full contract cost.
Are these positions paid?
No. Mobiles.co.uk cannot pay to move an option up the shortlist. CompareAMobile may earn commission when a reader uses a shopping link, but this never changes our ordering or guidance.
