What is a SIM only deal?
A SIM only deal gives you a monthly bundle of data, calls and texts without the cost of a new handset. You keep your existing phone and just pay for the plan — which makes it significantly cheaper than a standard pay monthly contract. Most people could save over £200 a year by switching from a handset contract to an equivalent SIM only plan.
One thing many people do not realise is that when a pay-monthly contract ends, most networks automatically move you onto a rolling SIM only plan — often not on the best available rate. It is always worth comparing deals at that point rather than letting your plan roll over unchecked.
How much data do you actually need?
Most people overestimate how much data they need. According to Ofcom, the average UK mobile user consumes around 10GB per month — but the majority of people use considerably less.
| Usage type | Monthly data | What it covers |
|---|---|---|
| Light user | Under 3GB | Browsing and social media mostly on Wi-Fi |
| Average user | 3 to 10GB | Streaming music, occasional video on the go |
| Heavy user | 10 to 30GB | Regular video streaming, working remotely |
| Very heavy user | 30GB+ | Constant streaming, no home broadband |
30-day vs 12-month contracts
The two most common SIM only contract lengths are 30-day rolling plans and 12-month contracts. Here is how they compare:
30-day rolling
- ✓ Cancel anytime
- ✓ No long-term commitment
- ✓ Usually no credit check
- ✗ Slightly higher monthly cost
12-month contract
- ✓ Lower monthly price
- ✓ Good balance of value and flexibility
- ✗ Locked in for 12 months
- ✗ May have annual price rises
Watch out for annual price rises
Many of the major networks apply an annual mid-contract price rise, typically in April. Several networks including Smarty, giffgaff, VOXI, iD Mobile and Lebara currently offer deals with no in-contract price rises.
| Network | Price rise policy |
|---|---|
| O2 | Annual rise each April, currently £2.50/month |
| Vodafone | Annual rise each April, currently £1.50/month |
| Three | Annual rise each April, currently £1.90/month |
| EE | Annual rise each April, linked to CPI + 3.9% |
| Smarty, giffgaff, VOXI, iD Mobile, Lebara | No mid-contract price rises |
What are MVNOs?
Most of the networks on this page are MVNOs — Mobile Virtual Network Operators. They buy capacity from one of the big four (EE, O2, Three or Vodafone) and resell it at a lower price. The signal travels through exactly the same masts — there is no technical difference in coverage.
| Network | Runs on |
|---|---|
| giffgaff | O2 |
| Smarty | Three |
| VOXI | Vodafone |
| iD Mobile | Three |
| Asda Mobile | Vodafone |
| Lebara | Vodafone |

Frequently asked questions
Are SIM only deals cheaper than phone contracts?
Yes. With a SIM only deal, you only pay for your data, calls and texts — not the cost of a handset. Monthly bills are typically much lower as a result. Most people could save over £200 a year by switching from an expiring handset contract to an equivalent SIM only plan.
Do I need to pass a credit check?
For 12-month and 24-month contracts, most networks will run a credit check. For 30-day rolling plans, approval is usually faster with less stringent checks. Smarty, giffgaff and Lebara all offer no-credit-check plans.
Can I keep my phone number when I switch?
Yes. Text PAC to 65075 to get your Porting Authorisation Code. Give this to your new network when signing up and your number will transfer automatically — usually within one working day.
Do SIM only deals include 5G?
Most modern SIM only deals include 5G at no extra cost, provided you have a 5G-compatible handset and live in an area with 5G coverage.
What is an eSIM?
An eSIM is a digital version of a SIM card built into your phone. You activate a plan directly on your device without needing a physical card. Most modern smartphones including iPhone 14 and later support eSIMs.
Do SIM only deals include roaming?
Many networks include EU roaming at no extra cost. Some networks like Lebara and Three also include roaming in a wider range of destinations. Always check the roaming terms before signing up if you travel frequently.
