Most people pick a phone plan by guessing how much data they need, then either run out before the month is over or pay for gigabytes they never touch. A clear price list makes that choice far easier. When every allowance from a light 5GB to a heavy 120GB sits side by side, with the same 30-day term and no contract, you can match the plan to the way you actually use your phone and change it whenever your habits change.
This guide walks through a full range of SIM only deals on 30-day terms, what each tier includes, and how to work out which one fits you.
The Full Price List at a Glance
| Plan | Data | Standard price | First month | UK calls and texts |
|---|---|---|---|---|
| UK Plan Smart | 5GB | £5 | £3.50 | 1000 |
| National Plus | 30GB | £10 | £5 | Unlimited |
| UK Plan Super Extra | 75GB | £15 | £7.50 | Unlimited |
| UK Plan Mega Plus | 120GB | £20 | £10 | Unlimited |
| UK Plan Unlimited | Unlimited | £25 | £12.50 | Unlimited |
Every plan runs for 30 days and includes 100 international minutes. The first-month price is a one-off discount, so after that the plan renews at its standard price.
What Each Allowance Is Good For
5GB: Light Users and Second Phones
UK Plan Smart costs £5, with the first month at £3.50 (30% off). It comes with 5GB of data, 1000 UK minutes and texts, 100 international minutes and EU roaming up to 5GB. That is plenty for messaging, email, maps and a little social media, and it suits a backup phone, an older relative or anyone who is mostly on Wi-Fi at home and at work.
30GB: The Everyday Middle Ground
National Plus lists at £10 and drops to £5 for the first month. The 30GB allowance covers regular streaming on the commute, video calls and social apps, and you get unlimited UK calls and texts plus EU roaming up to 12GB. For many people this is the sweet spot between price and data.
75GB and 120GB: Streaming and Hotspot Users
UK Plan Super Extra gives 75GB for £15, with £7.50 for the first month, while UK Plan Mega Plus gives 120GB for £20, with £10 for the first month. Both include unlimited UK calls and texts and roaming in the EU and India up to 12GB. These tiers make sense if you watch a lot of video away from home or share your connection with a laptop or tablet.
Unlimited: No More Counting
UK Plan Unlimited costs £25, with £12.50 for the first month. Alongside unlimited data and unlimited UK calls and texts, it has the largest roaming allowance on the list, with up to 35GB in the EU and India. If you never want to check your usage again, this is the plan to look at.
How to Work Out Your Data Needs
The easiest way to choose is to look at your phone’s own data statistics for the last few months. Most phones show mobile data used per billing period in the settings. Add a buffer of around a quarter for busy months, and pick the tier just above that number. As a rough guide, an hour of standard-definition video streaming uses around 1GB, music streaming uses far less, and messaging and browsing use very little.
Because these are 30-day plans with no contract, you can move up or down a tier when your needs change, for example upgrading for a month of travel and dropping back afterwards. That flexibility is one of the main reasons people choose no contract SIM only plans over long fixed deals.
Before You Switch
- Check that your phone is unlocked, or ask your current provider to unlock it.
- Request your PAC code by text if you want to keep your number.
- Decide whether you want a physical SIM or an eSIM, if your phone supports it.
- Remember that the first-month discount applies once, so budget for the standard price from month two.
The Bottom Line
A single price list from 5GB to 120GB and beyond makes it simple to buy only what you use. Light users can stay under £5 a month, everyday users get 30GB for £10, and heavy streamers can step up to 75GB, 120GB or unlimited data without signing a contract. With a 30 day SIM only plan you stay in control of both your data and your spending.
