Best SIM only deals

A SIM Only deal is a mobile plan that includes data, minutes and texts without a phone, allowing you to use your existing phone without paying for a new one. You use your existing phone with a SIM Only contract, making it a cost-effective way to stay connected, with flexible 30 day rolling or 12 month contracts that let you choose the level of commitment that best suits your needs. 

A SIM Only contract gives you a monthly allowance of data, minutes and texts without including a new phone. You simply use your existing phone and insert the SIM card to start your plan. Options include a 30 day rolling plan or a 12 month SIM Only contract, depending on the level of flexibility required.
You can also keep your existing number when switching. Find out more on our Switching page.

A rolling SIM Only contract is a 30 day mobile plan that automatically renews each month, giving you flexibility without a long-term commitment.
With a rolling SIM Only deal, you can change, upgrade or cancel your plan at any time without early termination fees, as long as you provide 30 days’ notice. This makes it a flexible option if your data needs change or if you don’t want to commit to a longer contract.

You’ll still receive a monthly allowance of data, minutes and texts, just like other SIM Only plans, but with the added benefit of short-term flexibility.

A SIM card is a small chip that connects a phone to a mobile network. It can be moved between unlocked phones and is used to activate a mobile plan, as well as store basic information such as contacts.
SIM cards are available in different sizes, including Standard, Micro and Nano SIM, although most providers supply a multi-size SIM that can be adjusted to fit the phone model.
Some phones also support eSIM, a digital SIM that is built into the phone. With an eSIM, a mobile plan can be downloaded directly without needing a physical SIM card.

Talkmobile offers some of the cheapest SIM Only deals in the UK, with plans starting from under £6 per month on 30 day rolling contracts and under £10 on 12 month options.
These low-cost and affordable SIM Only plans vary based on data allowance and contract length, making it easy to find a deal that suits both light and heavy data users. All plans include unlimited minutes and texts, offering strong value without the cost of a new phone.

Yes, you can easily keep your existing number when moving to a SIM Only deal.

Once you provide this code when joining Talkmobile, your number will be transferred to your SIM Only plan.
