What Is a SIM Only No Contract Deal?

A SIM only no contract deal is a monthly rolling plan that provides you with minutes, texts, and data—without the commitment of a long-term contract or the need to buy a new handset. You simply receive a SIM card to use in your existing (unlocked) mobile phone, and pay one straightforward fee each month[2][3].

  • No phone included: You supply the handset.
  • No lengthy lock-in: Cancel or switch with just 30 days’ notice[8].
  • Pay for service only: Costs typically much less than bundled phone contracts.

Why Choose a SIM Only No Contract Deal?

SIM only no contract deals are all about flexibility, value, and ease. These plans are perfect for anyone who:

  • Has a phone they love and don’t want to upgrade.
  • Wants to avoid lengthy financial commitments or credit checks.
  • Prefers to adjust or cancel their plan based on changing needs.

With lower average monthly costs (since you’re not paying off a device), you save money while maintaining the freedom to move providers whenever you wish[1][2].

How Do SIM Only No Contract Deals Work?

Getting started is straightforward and hassle-free:

  1. Choose a plan that matches your usage for minutes, texts, and data.
  2. Order or pick up a compatible SIM card from your chosen provider.
  3. Insert the SIM into your (unlocked) phone—most UK phones sold after 2021 are already unlocked[2][3].
  4. Activate your new plan. You can even keep your existing number by requesting a PAC code (text ‘PAC’ to 65075)[1].
  5. Enjoy monthly rolling terms. Cancel or switch any time with 30 days’ notice—no penalties[8].

FAQs

1. What exactly is a SIM only no contract deal?
A no contract SIM only deal is a monthly plan offering minutes, texts, and data—without requiring a lengthy contract or bundling a new phone. You use your existing unlocked handset and can cancel anytime with short notice[2][3][8].

2. Can I keep my old number with a new SIM only plan?
Yes! Simply request your PAC code from your old provider (text ‘PAC’ to 65075) and give it to your new provider to transfer your number hassle-free[1].

3. Are SIM only no contract deals cheaper than contracts with a phone?
Usually yes. You’re not spreading the cost of a new phone, so you only pay for your allowance of calls, texts, and data—making these plans more affordable[1][2].

4. What if my phone is locked to a network?
Phones sold in the UK after December 2021 must be unlocked. If yours is older, you may need to request an unlock from your current provider before switching SIMs[2][3].

5. Can I get 5G or unlimited data with no contract SIM only plans?
Absolutely—many providers offer 5G coverage and unlimited or high-data plans on rolling monthly terms. Compare available options based on your location and data needs[1][5].

6. Will I have to pass a credit check?
Most one-month rolling SIM only deals don’t require a credit check, as you’re not purchasing a phone or signing a long-term agreement[2][6].

7. Where can I compare and buy the best SIM only no contract deals?
Check Contract Deals’ no contract SIM page for current offers, or use major comparison sites like uSwitch and MoneySuperMarket.
